A simple supported steel beam when loaded with a force of 100 kg at A is found to deflect 10 mm at B. What force at B would cause a deflection of 2.5 mm at A
Sand drops from the bottom of a hopper into a horizontally moving belt conveyor. If the conveyor is travelling at 2000 fpm and the sand is fed at the rate of 1500 1b/min, the force necessary to drive the conveyor would be
