Problem 1 The stresses at a certain point in a cast iron machine part are Ox= 40 MPa, Oy= -50
MPa and Txy = 30 MPa (C. W). Determine analytically the safety factors
guarding against static failure according to the Coulomb-Mohr and
modified Mohr theories. The ultimate tensile and compressive stresses of the cast
iron are 150 MPa and 600 MPa respectively.

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.
