The edges of an aluminum cube are `10 cm` long. One face of the cube is firmly fixed to a vertical wall. A mass of `100 kg` is then attached to the opposite face of the cube. Shear modulus of aluminum is `25 xx 10^(9) Pa`, the vertical deflection in the face to which mass is attached is

The edge of a cube is 4 cm . Find the ratio of its tota surface area to the area of its vertical faces.

One of the square faces of a metal slab of side 50 cm and thickness 20 cm is rigidly fixed on a horizontal surface. If a tangential force of 30 N is applied to the top face and it is known that the shear modulus of the material is 4 xx 10^(10) N//m^(2) , then the displacement (in m) of the top face is

Two parallel forces of 4000 N are applied tangentially in opposite direction to the opposite faces of a metallic cube of side length 0.25 m. The shear modulus of the material is 80xx10^(9) Pa. Then the displacement of the upper surface relative to the lower surface is

Consider an Indian rubber cube having modulus of rigidity of 2xx10^(7) dyne cm^(-2) and of side 8 cm. If one side of the rubber is fixed, while a tangential force equal to the weight of 300 kg is applied to the opposite face, then find out the shearing strain produced and distance through which the strain side moves .

A uniform nickel wire of length 3.14 m and radius 10^(-3) hangs vertically. If a mass of 20 kg is attached to its free end. The extension in the wire is, (Young's modulus of nickel =20xx10^(10)N//m^(2) )

A lead cube of side 20 cm is subjected under a shearing force of magnitude 5.6 x 10^6 N . If the lower face of the cube is fixed, then the displacement in the upper face is (If shear modulus of lead is 5.6 * 10^6 N/m^2)
