Hi! First off, I'm just an upcoming junior in Civil Engineering, and I have little teaching experience. I have done well in engineering classes so far though, and I've thought about ways to improve how classes are taught. While there are some widgets for engineering, like those in MATHTAB and...

As a systems engineer I have thought a lot about entropy in trying to get a better intuitive sense for what it is, at a more macro level than it is usually discussed. I have some ideas and am looking for a forum to present and explore them with others. I wish to discuss more from an...

Further given: - every beam is infinite stiff - pulleys are massless - cables don't stretch, no slip, and frictionless. -Every pulley has a diameter D except pulley Q. Pulley Q has diameter 0.5*D So what I don't understand is how to calculate/determine the velocity at R and S. Can someone help...

I couldn't do it

Im unsure if I am on the correct track or have gone off on a tangent. Any help or guidance would be appreciated. CMRR=20log10(Adiff/Acm) 120=20log10(10^5/Acm) 120/20=log10(100,000/Acm) 6=log10(100,000/Acm) taking antilogs 1,000,000=100,000/Acm Acm=100,000/1,000,000 Acm=0.1Max amplified...

Summary:: I was wondering if there was a map of electronics engineering much like this does for physics (https://www.youtube.com/watch?v=ZihywtixUYo). I realize that looking at undergrad course outlines should give a decent picture of the field. However I am looking for a more comprehensive...

How did you find PF?: Google Hi, I am very undecided and confused about what engineering path(I don't know if I should say path or field) I should follow, so I am here to get some information about each engineering path. At first, I was interested in biomedical engineering, but then I changed...

Hi everyone, I hope I can articulate what I'm thinking, as I'm unsure if this is specifically an "engineering job" problem or a job in general problem. I graduated with a BSEE, got an MS right after, and have worked in two companies so far. I had a pretty good gpa for both, over 3.6, so I...

Please help me A certain steel tape is known to be 100000 feet long when the temperature of 70°F . When the tape is at a temperature of 10°F, what reading corresponds to a distance of 90000 ft? Coefficient of linear expansion of the tape is 5.833 x 10-6 per °F.

The landing speed of an airplane is 360 kph. When it touches down, it puts on its brakes and reverses its engines. The retardation in its speed is 0.2 times the square root of its speed. Determine the time elapsed in seconds from the point of touchdown until the plane comes to a complete stop.

A car starting from rest picks up at a uniform rate and passes three electric post in succession. The post are spaced 360 m apart along a straight rod. The car takes 10 seconds to travel from the first post to the 2nd post and tales 6 seconds to go from the 2nd post to the 3rd post. Determine...

The depth of the crater of the Taal volcano was calculated in the following manner: From a helicopter flying vertically upward at 6m/s. A small bomb was released at the instant the helicopter was 20m above the crater surface. The sound of explosion was heard 9sec later. If the speed of sound is...

Hi, I was reading about Euler-Bernoulli beam theory on Wikipedia and couldn't understand few points under the history section. Source: https://en.wikipedia.org/wiki/Euler–Bernoulli_beam_theory How were they making bridges and buildings back then if they were not 'trusting' science? Isn't...

Long times have been that I've decided changing my job from engineering to theoretical physics. Because I don't want to learn the rules that have been discovered by any scientists and make a situation about getting it real :]. I want to learn how the rules of nature is being discovered and what...

Summary:: Having the following dates:

So, a website in which I just enter an element or an Isotope and it just lists all the relevant experimental data like mass, mass-defect binding energy etc. Also resources for the absorption data, resources to explore Monte-Carlo simulations, and other calculation tools would be awesome. Just a...

I have calculated V3 to be 294.62sin(1800 pi t + -0.56)V I am confident this is correct but I now need to work out the frequency of the waveform, I believe it may be 900 but I am not too sure if my calculations are correct and I can't find anywhere on line that aids me in this particular instance.

Please can you help with a question I am struggling with. I have done as much working out as I could until I was completely stumped: Calculate the concrete volume that is required to keep the sluice gate AB closed, assuming that the only resisting force is the friction between the concrete...
