EXERCISE 2 A hollow cylinder has length 50.0 cm, internal diameter 5.0 cm and external diameter 6.0 cm. A force of magnitude 1.0 kN acts at each end of cylinder so that the cylinder is being compressed. Determine the compression of cylinder. ( Young's modulus for the material of the Cylinder = 7.0x10'º Nm²² ) Answer: 8.3x106 m
