A tangential force (F) is applied on the surface of the cuboidal box as shown in figure. Find out the shearing strain.
Body shown in figure is square aluminium plate of side 0.2 m. When a tangential force of 1×106 N is applied to the top face, the resulting shear strain is 0.01. If modulus of rigidity is η=0.3×1011 N/m2 then thickness of plate is x3 cm. Here x is
