An iron cylinder and a silver cylinder have the same length, l = 10cm, and different cross-sectional areas, are = 4 cm 2 , and aag = 5.0cm2 . the cylinders are connected to each other by a string which passes over a pulley. initially they are held in place so that each is half submerged in mercury. when the cylinders are released, the iron cylinder moves upward through a distance x and the silver cylinder moves downward through a distance x, allowing the system to come to equilibrium. find x. you will need the densities of iron, silver, and mercury, which can be found in your textbook.

An electric motor is used to drive a power press which makes steel turning moment diagrams 323 pressings from a metal sheet. the motor runs at a mean speed of 50 rev/s. the torque required is 10.0nm for 0.2s, followed by 1.0nm for0.3 s with this sequence then being repeated. what is the minimum power required of the motor and the moment of incrtia required for the t1ywhcel if the speed fluctuations are to be restricted to 1.5%?
