a rod of length 0.5m is fixed in a wall horizontally a body of mass 20kg is attached at its pre-end which hit by10cm if area of cross section of the rod is 5mm^2..Find the shear modulus of rod material??

shear  stress =  force /area = 20 * 10 N / 5 * 10^-6 m&2
         = 40 * 10^6 N/m^2

Shear strain = theta in radians 
    tan theta  =  10 cm / 50 cm = 0.2
     theta = 0.197 radians or nearly  0.2  radians

 shear modulus = G =  shear stress / shear strain = 200 * 10^6 N/m^2
