A cylindrical part of diameter d is loaded by an axial force P. This causes a stress of PyA, where A 5 pd2y4. If the load is known with an uncertainty of 610 percent, the diameter is known within 65 percent (tolerances), and the stress that causes failure (strength) is known within 615 percent, determine the minimum design factor that will guarantee that the part will not fail.

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.
