2. The force (not just its magnitude) due to a solid body being compressed/stretched in the direction is given by Fe = EA L AL where E is the object's Young's modulus, A is its cross-sectional area, L is its resting length, and AL is the resulting change in the the object's length due to the force Fe. From the similarities between Fe and Hooke's law, write down the expression for the potential energy stored in a stressed solid body.

Q#4: A shaft having length equal to 10 m and diameter equal to (57) mm is simply supported at both ends. The shaft carries four masses (157) kg, (207) kg, (257) kg and (307) kg. These masses are located at a distance of 1.5 m, 2.5 m, 5.5 m and 7.5 m from the left hand side support, respectively. The modulus of elasticity, E, for the material of the shaft is 200 GN/m2 and mass density for the shaft material is 7500 kg/m3. Determine critical speed of the shaft in revolutions per minute for the following two cases: Effect of the mass of the shaft is neglected. Effect of the mass of the shaft is considered.
