Draw a block and tackle system of pulleys with a velocity ratio of 5 is used to raise a mass of a 25kg through a vertical distance of 40cm at a steady rate.
Draw a block and tackle system of pulley with a velocity ratio of 5. A block tackle, with a velocity ration of 5 used to raise a mass of 25k. through a vertical distance of 40CM a stead by rate if the effort is equal to 60N determine
A= the distance moved by the effort
B= the work done by the effort in lifting the load
C= the loss in energy involved in operating the machine.
