To most efficiently solve this problem, you should divide the rod into pieces of charge that consist of To most efficiently solve this problem, you should divide the rod into pieces of charge that consist of thin lines of charge of length L and a very small cross section. thin "slices" of the rod cut parallel to the axis of the rod. thin "slices" of the rod cut perpendicular to the axis of the rod.

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.
