A counter-rotating eccentric mass exciter consisting of two rotating 400-g masses describing circles of 150-mm radius at the same speed but in opposite senses is placed on a machine element to induce a steady-state vibration of the element and to determine some of the dynamic characteristics of the element. At a speed of 1200 rpm a stroboscope shows the eccentric masses to be exactly under their respective axes of rotation and the element to be passing through its position of static equilibrium. Knowing that the amplitude of the motion of the element at that speed is 15 mm and that the total mass of the system is 140 kg, determine
(a) the combined spring constant k,
(b) the damping factor c/cc
Some rear view mirrors produce images of cars behind you that are smaller than they would be if the mirror were flat. What is the mirrors radius of curvature if cars 25.0 m away appear 0.33 times their normal size?
A 400kg baby grand piano is raised to the roof of a 100m building. If the cable breaks as it reaches this height, what will its velocity be the instant prior to impact
Does the time required for the charge on a capacitor in an RC circuit to build up to a given fraction of its final value depend on the value of the applied potential? Why or why not.
