Shear Definition and 575 Threads

So as you can see, the drawing I've attached shows two bolts through those 3 plates. There are the shown forces acting on the plates, and the maximum allowed shear stress is given to be 110 MPa. You're supposed to determine the minimum diameter required for the bolts. Also, the forces are...

shear force diagrams simple stuff hey!? hey guys this is probably very straight forward stuff for u but i have an example question on a loaded beam. there is a UDL, 2 pure couples and 2 fixed points. now how do i do the shear force and bendin moment diagram for this really lookin forward...

A child slides across a floor in a pair of rubber-soled shoes. The friction force acting on each foot is 25 N, the cross-sectional area of each foot is 20 cm2, and the height of the soles is 5.0 mm. Find the horizontal distance traveled by the sheared face of the sole. The shear modulus of the...

A large sponge has forces of magnitude 17 N applied in opposite directions to two opposite faces of area 43 cm2 (see the figure below ). The thickness of the sponge (L is ")3 cm. The deformation angle (g is ")8.4°. (a) What is delta x? (b) What is the shear modulus of the sponge? delta x =...

I have a rectangular block (propellar) with known width, thickness, legth, and uniform density. It is spinning at a constant angular velocity around its centroid. Then it is decelerated at a constant rate to rest. I want to find the relation between the radial distance from the centroid and...

I have heard the term moment being used quite often in physics (like a moment in the distributions of mass within closed systems, moments of inerta, as well as torque), but it has never been offically explained to me. I was attempting to do a problem about the bending of a pliabile beam to one...

Can anyone draw me a correct Bending moment diagram and shear force diagram for this beam? i have drawn the shear force diagram for this case but I do not know how to draw the bending moment disgram for this case because this question involve a constant moment. Normally the rule for bending...

http://www.savefiles.net/d/ieiwoixnjfw.html Can anybody pls write for me the shear stress eqn using singularities or heaviside function in which i have attach the in the file above pls help thanx

http://www.sendspace.com/file/czhuhx http://www.sendspace.com/file/gviky7 pls have and look at the link above and kindly tell me how to draw the bending moment and shear force diagrams.this is in the chapter of statics mechanics thanx

does anybody has any websites or relevant material on how to draw the shear force and bending moment diagram?? pls help... thanx

Hi guys, For a Engineering Project, we will be suspending a bridge using a cantilever system. We have to draw the shear force diagram (SFD) and bending moment diagram (BMD) for the horizontal and vertical members. The arrows on the diagram represent the loading from the bridge itself. I...

I need help getting started on this. Question: An iron bolt is used to connect two iron plates together. The bolt must withstand shear forces up to about 3200 N. Calculate the minimum diameter for the bolt, based on a saftey factor of 6.0. Here is what I know so far. Shear Strength is 170...

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

In mechanics of materials we often look at elemental cubes or planar squares, and we write the normal stress and shear stress acting on the faces. Why are the internal moments acting on each face omited? When we cut a frame-machine, we include a shear, normal and moment, why not for the...

On a homework assignment where a device contains three pin connections, we are asked to find the shear stress on two of the pins ( single shear) and a third which is experiencing double shear. For the single shear, I just took the force being applied at the pin connection and divided it by the...

Where can I found an expressionfor the shear stress tensor in GR with some explanation about it? Thanks blue

So I've got this velocity distribution for laminar flow between parallel plates. \frac{u}{u_{max}} = 1 - (\frac{2y}{h})^2 h is the distance between the plates with the origin placed midway between the plates. I'm assuming this is for water flowing at 15 deg C with u_{max} = 0.10 m/s and h...

Imagine a moderately long beam fixed at one end to a wall. Near the end of the beam, a very heavy weight is kept on top of the beam. At the same spot, two small beams are fixed under the main beam in a V shaped configuration such that the two beams form a sort of "press fit" i.e. they exert a...

I have a problem that I'm not sure how to approach. "If the shear stress in steel exceeds about 4.00 x 10^8 N/m^2, the steel ruptures. Determine the shearing force necessary to (a) shear a steel bolt 1.00 cm in diameter and (b) punch a 1.00 cm diameter hole in a steel plate .500 cm thick. I...

I am stuck on some homework - I see many options, but not which is the correct set. A simple 2D shear velocity field: v (x-direction) = v (x-dir)(y,t), v (y-dir) = 0, a barotropic flow with uniform density. Does this flow involve expansion, contraction, rotation and or deformation? How does...

Please, say me what are shear forces. I've been looking for it because I was studying a phenomenon called hydraulic jump. In this example, are these forces caused by the cohesion forces?

(i guess this should be easy, but I'm struggling with this section...) I'd appreciate help! I'm not quite sure how to do this. I posted the diagram at my web site...the question is also there, but I typed it here just to give you an idea of what it is about. Thanks! The website...

A force of 500 N is applied at an angle of 37 degrees to the surface of the end of a square bar. that surface is 4.0 cm on a side. what are the compressional & shear stress on the bar? material processing class and i don't know the equation or where to start someone help please

A 1260kg freight elevator is supported by a steel cable of diameter 34.9mm. It is loaded with a crowd of people collectively having a mass of 2850kg and it is descending. a) What is the strain on the cable while the elevator is descending at the constant speed of 2.30 m/s? b) What is the...

Hello, I have problems with the "Engineering Shear Strain" formulas from the following website : http://www.efunda.com/formulae/solid_mechanics/mat_mechanics/strain.cfm I agree with the formulas and the graph on the left, but I don't with it on the right. On the left graph du/dy and...
