4β41. the 10-mm-diameter steel bolt is surrounded by a bronze sleeve. the outer diameter of this sleeve is 20 mm, and its inner diameter is 10 mm. if the yield stress for the steel is (sy)st = 640 mpa, and for the bronze (sy)br = 520 mpa, determine the magnitude of the largest elastic load p that can be applied to the assembly. est = 200 gpa, ebr = 100 gpa.

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.
