Question

An aluminum sphere 20 mm in diameter, is pressed with a load of 300 N against a hard-plastic sphere 40 mm in diameter. The elastic modulus of aluminum is 69 GPa and that of the plastic is 82 GPa. The Poisson’s ratios for aluminum and plastic are respectively 0.33 and 0.206; Determine

A) The contact circle diameter, B) Maximum contact pressure, C) Maximum shear stress in the wheel using stress curves for contacting spheres

Answer 1

ANSWER:--

SHEAR STRESS:---Shear Stress. Shear Stress (t) is a measure of the force of friction from a fluid acting on a body in the path of that fluid.
