Joints Definition and 67 Threads

I'm joining a flange and a cap using 9 bolts with a steel gasket placed in a 'o' ring. To ensure that the joint is leak proof, I need to calculate the load distribution in the area between two bolts for a given torque in the bolt[please refer to the figure, where the lines indicate the area...

The problem is attached. I have to solve for the force in the member BC. The thing I need help with is solving for the two attachments. I already broke it down into the forces and directions, but what do I do with the lower attachment? How do I find the x displacement of point G from E if I'm...

I have the truss shown, I'm supposed to find the internal force for each of the vertical members...I understand method of joints and method of sections, but can you use both method of joints and sections in the same problem...for example I found Ly=52.5 and Ry=32.5 using moments and summing in...

http://s44.photobucket.com/albums/f46/maximus11373/?action=view&current=w-1.jpg&newest=1 An inclined member is braced with a glued block, as shown. The ultimate shear stress in the glued joint is 1050 psi. Determine the dimension X at which the glued joint will fail. I know that...

Hello, I have a rod of two different diameters and I'm trying to find the stress concentration at the chamfer between the two diameters. I understand how to find the stress concentration factor, K, if the joint was a fillet (using r/d and D/d to find K in the appropriate table). However I can't...

There's a common belief that for any given bolted joint, the higher the preload, the longer the fatigue life. I’d like to challenge that preconception and suggest that increasing preload above that needed to keep the joint together and acting as a pair is generally a bad thing and results in...

SOLVED Homework Statement A bridge is made with segments of concrete 80 m long (at the original temperature). If the linear expansion coefficient is 1.2 x 10^-5 (1/degrees C), how much spacing is needed to allow for expansion for an increase in temperature of 50 degrees F? Answer in units of...

While solving for problems involving trusses using method of joints, how do i know which member is in compression and which is in tension? any help would be appreciated, this stuff's been bugging me for quite some time thanks and god bless

Hi there! Can anyone take me through the method of joints procedure for this truss? I am having trouble working out the reaction forces at the pin at joint A. Is there supposed to be a vertical component to the reaction force as well a a horizontal (seeing as it is a pin)? And if so where...

Hi, I am really stuck here. My problem is with determining the support reactions. I understand that this needs to be done first before working on each truss member. But I don't understand how to determine them. I have read and re-read all my available text and still stuck. The question I...

I have a case where I am trying to find the optimal place to put 3 rivet points (I will maybe even test with 4). The rivet points r subject to a force according to the picture, which vary 360. What I am seeking here is mathematical methods to find the optimal place to put the 3 riverts, so that...

Why is it that cold wet weather makes joints stiff and ache, the actual temperature of the joint can not change much can it?

Hey guys... i need help with method of joints... could some one explain to me how to do this. In my projects in engineering class we are constructing bridges and i want to understand what's going on. Any help would be aprreaciated. Excuse my spelling errors pls.

Hi, I was just wondering in what directions the reaction forces go in ball and socket joints? Are there reactions in the x, y, and z plane or just in 2 of those planes.

Hi, I have a question. I know this is way too impossible, but just curious, what could a person do with 360 degree joints (all joints)?

This seems like it should be easy but I am not sure what to do. Heres the problem: The picture to the problem is here: http://www.webassign.net/giancoli/9-65alt.gif "(a) Calculate the magnitude of the force FM required of the "deltoid" muscle to hold up the outstretched arm shown in Fig. 9-65...

I am struggleing here. Can anyone explain this concept to me? I don't understand how to first find the forces the supports exort and even if I did I don't know I I could proceed. Does anyone know a website that has a non-symetrical triangle that I can re-learn the basics off of. Or if some one...
