Degrees Definition and 679 Threads

See: https://www.tamuc.edu/cbe/ The degree people interested in STEM would do is the degree in General Studies with the free 66 electives done in their STEM field eg Math: https://www.tamuc.edu/programs/general-studies-competency-based/#tamuc-section-307935 Because it is so cheap and fast...

I am working on completing my degrees in Physics. Thanks for the platform and I hope to learn from you.

Hi, I am a middle schooler interested in pursuing a computer engineering degree. I may get up to a master's. I am interested in this field because I am interested in robotics, AI and some EE/CS stuff. What should I do this summer and next year (8th grade) to prepare and then what should I do...

Information online claims sun is 200 btu per sq ft in winter only when sun is perpendicular to plastic or glass of a green house. When sun hits glass or plastic at an angle there are losses. The steeper the angle the more losses will be. Is it possible to calculate how warm a green house will...

I just need to know how to find Θ in sin2Θ=0.51 I know I can use Θ = arcsin(0.51) but what about sin2Θ = 0.51

I was asked by an interviewer the number of degrees of freedom (in both translation and rotational senses) this part has with respect to each axis. Indeed I can share what I think of here, but I want to start it fresh and correct. If you were the interviewee, what would have been your answer and...

The other two movements make use of the wrist and can't be done without it so I see why they are considered to be degrees of freedom of the wrist.

I read there are 2 degrees of freedom in GR after boundary conditions specified. Does that mean 2 equations are enough for EFE equivalent? Those two seem like the amplitude and a phase.

Hi, I am not quite sure if I have solved task 2a and 2b correctly. For task 2a I would say, because of the constraints, that the system has only 1 degree of freedom. Since the vectors must always have an angle of Pi/4 to each other, this would mean that if one vector moves up, the other must...

In case of P holonomic constraints and N particles, I have 3N-P degrees of freedom and I have to look for 3N-P generalized coordinates if I want them to vary independently, but what about non-holonomic constraints? I know if I have N particles and P non-holonomic constraints, I still need 3N...

So recently what I've been seeing especially on reddit was that people have been praising CS over other IT degrees. Why is that a trend? Is it because other IT degrees are seen as "obsolete"?

Are dimensions the same thing as degrees of freedom? Would you say that a circle is a one dimensional object embedded in a two dimensional space?

Summary: ##M=3\left(n-1\right)-2j_1-j_2## Hi, I'm trying to get the degrees of freedom of a can crusher. So substituting I get ## \begin{array}{l}M=3\left(n-1\right)-2j_1-j_2\\ n=5\\ j_1=5\\ M=3\left(5-1\right)-2\cdot 5-0\\ M=2\end{array} ## And I would think it would be 1

I've recently learned that "Doctor of Engineering" degrees were a thing. It's seems to be a collaboration between the school and the company they work for. Does anyone here have one? Are these programs meant to be completed while continuing to work in industry full time? I couldn't find this...

I have been doing the resolutions of vectors on x and y-axis with making triangles and reference angles in all quadrants. But I want to calculate now how to find something like ##\sin 235## without the help of reference angles. I know we don’t need to. Calculator and Taylor theorem is handy here...

Why is cos (1)° = 0.9998? cos(60)° = ½? Thanks.

$\tiny{\textbf{7.3.a21 Radford HS}}$ find x in degrees $\quad 3\sin^2 x -\sin x-1=0$ rewrite as $3u^2-u-1=0$ quadradic eq $u=\dfrac{1\pm \sqrt{13}}{6}$ ok this is ?? are we going to have decimal degrees?

Hi, I want calculate the m = slope of a linear line WHEN I already know the angle in degrees of the line. Here is an example: I calculate with Excel the angle with the following function: =+DEGREES(ATAN(0.0874887)) and I get as result the angle of 5%. But how do I calculate the value...

I am a high school graduate planning to enter the Gator Engineering Program at Santa Fe. In the program I'll be transferred from Santa Fe to the University of Florida after 2 years. I am very excited for the program but I am restricted by only being able to major in a select few majors. The...

Hello there, im a physics student from Germany and currently in my second semester of a Bachelor of science. Lately i have become increasingly interested in woking in the Semiconductor Industry and I am currently reading the book "But how do it Know" by J. Clark Scott and i think it is really...

I have a spherical concave mirror with focal length of 65cm, radius of curvature of 130cm. I hold the mirror close to the eye at approximate 45 degrees and I reflect an object below it as shown in the image. The distance between the object and the mirror is 90cm, that is more than the focal...

Hi I thought that a bike could be simply modeled as two wheels attached by a rigid bar. If the wheels move without sliding, then there is one degree of freedom: one of the wheels moves and so does the other one since they are rigidly attached by the bar. Then, if the wheels can turn to the right...

I understand that the Kelvin scale begins at absolute zero and that the Kelvin scale may even be referred to as the absolute scale. As the units begin from a definite zero and increase with equal amounts of energy being added to the particles of the substance being measured (at equal intervals...

The rod itself should have 3 translational+2 rotational DOF. The particle on top of the rod has one additional DOF. So total should be 6. But answer given is 4. What I'm thinking wrong?

When physicists talk about a theory having local degrees of freedom, what is exactly meant by that statement? What are examples of theories with local degrees of freedom and what are examples of theories with no local degrees of freedom?

I have an empirical frequency distribution as for example below: ##f_{2} = \, \, \, 21## ##f_{3} = 111## ##f_{4} = \, \, \, 24## The theoretical distribution is determined by two parameters. So for a chi-square goodness-of-fit test there are actually no degrees of freedom left. Yet the...

The group ##\rm{O(3)}## is the group of orthogonal ##3 \times 3## matrices with nine elements and dimension three which is constrained by the condition, $$a_{ik}a_{kj} = \delta_{ij}$$ where ##a_{ik}## are elements of the matrix ##\rm{A} \in O(3)##. This condition gives six constraints (can be...

I am not understand the solution of the letter b and c given by the author. Since Cv = NfK/2, we have Cv/N = fK/2. Now, the degree of freedom of a N linear molecule is 3(trans) + 2(rot) + x, where x is the degree of freedom due the vibrational motion. I am having trouble to calc x, could you...

How would I go about calculating the time taken for the motor on page 2 to move the attached beam 360 degrees? Things such as the rpm and voltage are given in the attached data sheet for various different motors and you can reference anyone you like. I'm more interested in understanding what's...

Does anyone here have a masters degree in engineering, and then a second one in systems engineering ? I'm considering it because I can get help with the costs. I do systems engineering on electrical systems. So I see some possible advantages to getting both. I already have a masters in...

Suppose the equations of motion coming from GR in Schwarzscild spacetime for constant radius : $$\ddot{\theta}=\cos\theta\sin\theta\dot{\phi}^2$$ $$\ddot{\phi}=-2\cot\theta \dot{\phi}\dot{\theta}$$ $$\dot{\theta}^2+\sin^2\theta \dot{\phi}^2=C(onstant)$$ Could it be that by solving this system...

Lately I stumbled upon Western Governors University and they happen to offer online degrees in computer science and they also offer a degree in cloud computing. I was wondering does this online university seem legit? They seem to be regionally accredited by the Northwest Commission on Colleges...

Well, first of all is really good to say that we don't can appeal to quantum mechanics... So, i can see: Three degree of freedoms in translation on a space xyz +3 degree Three normal modes of vibration, but each normal mode has with it a potential and vibrational kinetic energy, so +6 degree...

(Note: I had this question posted at the intermediate level of difficulty for 11 days, but got only one, cryptic (to me) response that was rather quickly removed. So, I figured perhaps it's actually an advanced question, requiring more than a cursory understanding.) Assuming they've had an...

How is frost possible at 39 degree F

Lets say that a man with a standing height of 185cm bent his knee 30 degrees, how many centimeters will be reduced from his standing height? Assume his femur length is 60cm and his tibia (shin) length is 50cm. Can anyone give me a hint? I've tried to use trigonometry but i don't think i fully...

I'm trying to delve into the reason why this is so. It seems that there are 5 fundamental properties: P - Pressure V - Volume (specific) T - Temperature S - Entropy (specific) U - Internal Energy (Yes, there are other types of energy, but they are fully determinable from these 5 - e.g...

I've learned that for a particle having 3 degrees of freedom, its average energy is 3/2 kT. So for a particle having 'x' degrees of freedom, its energy should be xkT/2. So what is the use of given E = ax6 here? Please help!

In computer science we simplify lots of things down to arrays. Tensor equations just show the symmetries between these multidimensional arrays. And any model of a quark in our ordered world must have N degrees of freedom. The term called Degrees of Freedom is simple enough. For example a XYZ...

Planck states that all perfect crystalline system have the same entropy in limit T approaches zero,so we can put the entropy equal zero.Can we demonstrate that or is it only a presumption?

I can't understand how can we assign values greater than 90 to trigonometric functions as right angle triangle can't exist if one angle is more than 90 degree. For example if I say sin 30 according to me it means that ratio of perpendicular and hypotenuse is 1/2 at 30 degree but how can we say...

Hello, just wanted to know what is recommended after undergrad Physics to get into a career developing electric propulsion systems, or anything to do with Plasmas and future propulsion devices?

Two screws set 180 from each other. They are being used to clamp something between them. The object is able to move freely before clamping but is not able to compress. Tighten one screw (a) until it touches the object. Torgue the other screw (b) to 45 in-lbs. What is the resulting torque to a?

Hi Im current in last year of HND mechanical (100% distinction so far) and have HNC in general engineering (100% distinction). Im better at the research and piratical bad at exams (diffucult reading and writing and slow comperhention skills and expression using writting what i want to...

I delved a bit into the kinetic theory of gases and it got me wondered how it is discovered that the temperature, and thus heat capacity, is dependent on the number of degrees of freedom of a molecule or atom. I know that from the piston experiment a certain constant value can be found for the...

The problem is for us to consider a biconnected decomposition, and that proof for a graph, the degrees of all the vertices in a graph is even iff the degrees of all the vertices in all of its maximal biconnected components is even For solving that if the degrees of all the vertices in the...

Hey Guys/Gals i understand the general premise of this question and can calculate the solution but i am a bit confused. I am supposed to represent a generic state as a linear combination of the |-,x> , |+,x> basis vectors. However i don't know why, is the question actually asking for the...

Solution : the vegetable sector is 30 degrees, then you multiply it by 15 hectors of land, to find out the size of the farm. Correct me, if I'm wrong please. Thanks

What is the image that comes to mind/meaning behind the above statements where an objects is seen/appears 'to be (angle) diameter of the Earth? My interpretation is that if the given angle is drawn with one object as the vertex then the diameter of the second object subtends the given angle.(?)

At the moment, I am accepted to a few universities for statistics and data science programs (I was told there were a fair number of data scientists on this forum and the question applies more generally as well). One of these programs is in Finland at the University of Helsinki. I'm incredibly...
