The maximum stress occurs where shear load is maximum and maximum stress is at the center of the beam cross section if loaded in shear due to bending. It drops to zero at the top and bottom surfaces. The average stress is load divided by area ; maximum stress is dependent on shape of cross section and is 1.5 times load divided by area at the cross section center for rectangular cross section.
For shear due to twist, max shear stress in the outer surface.

What are called principle planes and principle stress?
The principle stress is a maximum tension stress in a body where shear stress is zero and it acts on the principle plane. If a body is under both tension and shear then the principle stress is higher than the initial tension stress. You can calculate this and find the principle plane angle using Mohr Circle analysis or equations.
What is the tensile strength of .375 bolt?
Tensile strength is a material propery, it does not depend on size. Look at a material chart to find its yield and tensile strenghts. Then use the stress equation, Stress = Force / Area to determine if your .375 bolt can handle the force on it. If your bolt is in shear, you need to find Shear strenghts.
Why are shear pins made from high carbon steel?
High carbon steel is stronger than low carbon steel with proper heat treatment. Thus, it will fail at a much higher load. ------------------------------------------------------------- Note: not all shear pins are high carbon heat treated steel. The pin needs to be nearly as strong, but not stronger than the material in which it is used, so that it shears off before the material it protects is damaged. thus a shear pin for a bronze shaft may actually be made of copper. Obviously the stronger the material, or larger the diameter of the pin, the more load it can handle, but it needs to shear off before the material it protects is crushed. I'd assume that a high carbon steel shear pin is being used on a machine made of some high tensile strength stainless alloy.
Find the yield strength from a stress-strain graph?
Follow the graph's positive slope (across the first quadrant) until the graph is no longer linear. The yield strength is determined to be the last point (with concern given to the stress value) on the linear section. After this point the graph is irregular because the material has failed to a point of no return and can no longer handle the load (stress).
How do you calculate the Youngs modulus of a material?
To find the Young's modulus of steel or any other material you require a plot of it's deformation response to loading. Specifically it's axial stress vs axial strain. From this you need to find the gradient of the straight line portion of the curve where the material is behaving elastically and obeying Hooke's law. This is essentially stress / strain and gives you Young's modulus.
What are called principle planes and principle stress?
The principle stress is a maximum tension stress in a body where shear stress is zero and it acts on the principle plane. If a body is under both tension and shear then the principle stress is higher than the initial tension stress. You can calculate this and find the principle plane angle using Mohr Circle analysis or equations.
What is the shear strength of five different papers?
to find the shear strength of five different papers you use the formula shear stress equals major principal stress minus minor principal stress divided by two. Shear strength of paper depends on what they paper is made from.
How do you find ultimate bending moment of steel beams?
Assuming linear elastic bending with small deformations and planes perpendicular to the neutral axis remain plane after bending, then for a rectangular beam: Moment = (Yield Stress)*(Second Moment of Area)/(Distance of surface to Neutral Axis) For Ultimate Bending Moment, assume stress is uniform throughout the beam, and acting through half the distance from surface to neutral axis, then: Moment = Stress * (Area/2)*(h/4 + h/4) For a better visualization check out Popov's textbook, Engineering Mechanics of Solids, Chapter 6, Section 6.10
What is the significance of shear center?
It is very important to find the shear center for the beams or sections that are undergoing majority of the load under torsion or twisting then the material will not fail under torsion as at shear centre there will be no effect of torsion or twisting. It will fail only by bending or any other force.
What is the tensile strength of .375 bolt?
Tensile strength is a material propery, it does not depend on size. Look at a material chart to find its yield and tensile strenghts. Then use the stress equation, Stress = Force / Area to determine if your .375 bolt can handle the force on it. If your bolt is in shear, you need to find Shear strenghts.
If a beam has a total volume of 60ft Find the maximum horizontal gap that the beam can span?
The Formula Would Look Like This...Volume/Height *Width...60Ft3in divided By 2Ft times 3Ft. I'm Prob In Your Class.
What is absolute maximum bending moment?
bending moment varies with the distance & the load carried by the beam. And also there is a hogging behavior and a sagging behavior occurs in the beam. According to the sign convention hogging and sagging bears opposite signs.(- & +). So if we are asked to find the maximum bending moment whether it is sagging or hogging we should consider the maximum value without considering the sign. That value is called maximum absolute bending moment.
How could you find out whether the shear strength depends on direction in which the paper is torn?
bcause shear stength measure in mass
How do you draw shear force and bending moment diagram for frames and arches?
There are two ways to draw the shear and moment diagrams. First is by writing the shear and moment equations and the other which is more rapid is by using the relationship between load, shear, and moment. For any of the two methods, the first step is to find the reactions at the support(s).Shear and moment diagram by writing the shear and moment equationsCut the beam in every segment where there is a change of load. Draw the free body diagram to the left of each exploratory section. Write the shear and moment equations and with these equations, you can easily draw the shear and moment diagrams. For examples and the detailed step by step step instruction on how to do this can be found by the link below:Using the relationship of load, shear, and momentDrawing the shear and moment diagrams by using the relationship between load, shear, and moment is more rapid than writing the shear and moment equations. The relationship are as follows:The slope of shear = LoadSlope of Moment = ShearArea of load = shear of a segmentArea of shear = moment of a segmentFor more in depth discussion of this subject with illustrations and solved problems, consider to visit the link provided below:

How does Tensile strength differ from Shear strength?
Shear strength measures the ability of a fastener to withstand a load at right angles to the axis of the fixing connection . Tensile strength measures the ability of a fastener to withstand a force along its axis
Can you tell me a good website to find high shear mixers?
A website like www.fluko.com is a great website to find a good quality high shear mixer. Same with www.ikausa.com and www.highshearmixers.com. Hopefully this helps!
