This is a problem for an intermediate materials class. There is a RIGID beam (does not bend) that is pinned at the top and has a 220 lb force on the bottom. There are two cables holding it in place (See diagram below). we are supposed to find the deflection of the beam at the bottom, and...

My statics text says the following: The relationship between axial stress and strain can be represented by the equation \sigma = E\epsilon "At higher levels of stress, the following nonlinear equation may be a better fit to describe the correlation between axial stress and strain: \sigma...

I need to understand how to work this type of problem before my final exam. How do you find the Maximum shear force and Maximum bending moment? Thanks

Ive been working on this problem for a little while now and basically, I don't know where to go. I have found the friction angle of 7 degrees but I really have no idea where to go next. My book doesn't have any examples like the problem. The problem looks a lot like a basic physics problem so I...

I am studying the statics of cable systems and I find it to be very interesting. :approve: I REALLY like statics. :biggrin: Such an interesting subject, anyways. My first question is this: When we have a system of cables supporting weights, say like traffic lights, we can assume the cables...

Ok this problem seems way too simple. I have worked it out without using any of the dimensions given. The problem is http://www.engr.colostate.edu/~elblunto/problem.jpg" My work is http://www.engr.colostate.edu/~elblunto/jonwork.jpg" I don't think the solution could be that easy...

I need to take Engineering Statics next semester, but the only time the class is offered conflicts with another class I have to take. There is no other class that I can take for my major next semester becasue every other class I need requires these classes I am taking next semester as...

Hi everyone, I have a statics question I am having a bit of trouble on. I don't know how I will put the diagram in here that it comes with but the question is "Determing the resultant of the coplanar concurrent force system shown. Compute the magnitude, sense, and angle of...

The problem is stated in the picture. And I drew the FBDs of the top half of the bolt cutter, as shown in the second page: Setting moment about A to be 0, I obtain -Q(1 in)-FBy*4 in=0 And By= -Q/4 lb Then setting moment about C to be zero. I obtain FBy(0.5 in)-20 in(75 lb)=0 Substitute in By...

Hello, I'm having trouble with a truss analysis problem. We are supposed to use the method of joints & the method of sections. We have to find all the external reaction forces and internal member forces. The method of joints is not problem, and I THINK I'm doing the method of sections...

I need some help in this problem to see if my game plan is right. My answer doesn't make sense, well to me it doesn't. A weight of 200 lb hangs from a frame of negligible weight, as shown. If the frame is in equilibrium, determine the loads acting on the frame at A and D. Use the fact that...

I have this assignment to hand in and I've been having problems remembering how to do these problems. I am not sure if my answers are correct. I have no idea how to do the third one if anyone can walk me through the solution. My answers are: #1: -59.8 #2: Tension=14715N Mechanical...

Q. The base of the freeway sign is attached to its foundation with four bolts.The four bolts must be able to resist the twisiting of the pole that is caused by the wind. Assume each bolt carries the same force. If the diameter of the bolt circle is 0.9m, calculate the horizontal (shear) force on...

I need urgent help in Statics I'm taking a Statics course in college right now. However, I wasn't able to get a book due to financial issues early on. Naturally I feel behind. Anyways, I have a test coming up and the teacher gave us four problems to solve as a study guide, saying similar...

Q. A Man, is pushing a copier machine, up an incline, which weighs 600 N. I need to find the frictional force, and the normal force. The free body diagram, I shall describe that to you. Weight of the machine acting downards. and if we resolve this weight we get mg sin theta along the...

First, on an unrelated note, I would like to share an anwser I think I found to be correct on a question I posted here a while back. I asked about how a smooth collar that was Not Pinned could prevent a moment. The problem I was faceing was the fact that in order to have "play" so that the...

Statics: Magnitude of vectors HELP! Could someone just tell me how to start this problem. I can't seem to think of anything right now.

Im reviewing statics and came across this problem. There is a beam pin connected at one end and roller connected on the other. There is a moment at the pin and a force somewhere along the beam. Then they section it to find the internal normal shear and moment. One of the things i found slightly...

now on question 8 of my homework, and i am starting to wonder if i;ve been getting these question right. It's to do with friction. Relativally simple question: When an object is stationary, would the formula to find the resolved friction be: F = (mew, u) R or F (is...

I am a newbie to fluid mechanics, and I am confused about the "hydrostatic paradox". To begin with, consider three containers. All three have the same base area (all circular), but the angle between the base and the "wall" are all different: Container 1: obtuse angle Container 2: right angle...

I would like to know if anyone could help me with the attached statics problems. I've worked on these for quite sometime and haven't been able to figure them out. Thanks

Hey, I'm having a lot of trouble with this physics homework problem: The cords BCA and CD can each support a max load of 100 lbs. Determine the max weight of the crate that can be hoisted at constant velocity, and the angle theta for equilibrium. The picture shows B attached to a pulley on...

In the problem: A horizontal boom supporting the sign is of uniform construction and weighs 50 N. If the sign weighs 150 N, the tension in the supporting cable is? Could I use the cross product and if so how? The answer is 350 N.

Hi I have a Physics re-test tomorrow on Statics. Since everyone failed the 1st statics test he is going to let us take another one (he's really nice :smile: ). It is not going to be like the 1st one. Where can I get some statics practice problems?? I'm doing ALL of the problems in the book...

1.) A uniform rod AB is 1.2 m long and weighs 16 N. It is suspended by vertical strings AC and BD. A block P weighing 96 N is attached at E, .3 m from A. The tension in the string BD is? http://img116.exs.cx/img116/2822/STATICS1.jpg I did: (.3m)(96N)+ (.9m)(16N) - (1.2 m)(x) = 0 x=36N...

A nonuniform bar is suspended at rest in a horizontal position by two massless cords as shown. One cord makes the angle theta1 = 36.9 with the vertical; the other makes the angle theta2 = 53.1 with the vertical. If the length L of the bar is 6.10m, compute the distance x from the left-hand end...

The question is stated below. I found out an answer but it doesn't seems to be correct to me. I made a few sketches to clear things up a bit, sorry for bad quality, too much compression. The simple truss of Prob. 4/2 is modified as shown in the figure, in that the angle of the support surface...

Argh! Statics is a pain. Argh, this problem is killing me. I've tried a couple of approaches to this proble. First approach was to break it into 4 'Y' shaped vectors with with points A,B,C,D as the centers of the 'Y'. No avail. The next approach was to couple the forces to the origin but the...

I've yet to taken a statics class yet, only physics one, but I'm having a hard time trying to define what an extension is on one of my home work problems. The problem is kind of long(about a page long), hopefully I will be giving a enough info on my problem. Here goes You have a pin jointed...
