A 15 in diameter rod is subjected to an axial tensile load of 45 kips. Compute. a. The normal stress developed on an inclined plane at an angle of 60° with the cross section of the rod. b. The maximum normal stress developed in the rod.

A picce of wire 10-in long is tied vertically. The wire has a diameter of 0.1-in and is used to support a load of 100-lb. What is the stress developed within the wire? 1.

Hertz contact theory can be used to determine the stresses due to contact between two spheres, which can be used approximate frictionless contact between the patellar and femoral components of a total knee replacement. Part a) Show on a sketch how the stresses at the surface vary from the centre of contact to the edge of contact. Part b) Make a sketch of an infinitesimal element of material at the centre of contact that shows the stress components. Identify the maximum principal stress, and write an expression for the maximum shear stress. Part c) Sketch a graph that shows how the maximum contact pressure varies with load and in a sentence explain why the curve has the shape it does.

Complete solution, please. Thanks!
