Polar modulus , Mechanical Engineering

Assignment Help:

Polar Modulus(Zp): 

It is the ratio of polar moment of the inertia to outer radius.

Zp = J/R

Polar Modulus of solid body (Zp) =[  ?/32.D4]/D/2 =  ? .D3/16

Polar modulus of hollow body (Zp) =[?   /32. (Do - Di  )]/D/2 = [  .(Do - Di  )/Do]/16
