A machine with a velocity ratio of30 moves a load of 3000 n when an effort of 200 n is applied.the efficiency of machine is 30%,50%,60%25%,75%
Answered by Damon
3,000 Newtons / 30 = 100 Newtons required for a PERFECT machine
we needed twice as much
so efficiency is 0.50 or 50%

The efficiency of the machine is 25%.
