Question

A machine with velocity ratio 5 requires 1000J of work o raise a load of 600N through a vertical distance of 1.25m
find i.work output
ii.the efficiency of the machine
iii.the mechanical advantage of the machine

Answer 1

output: 600*1.5 joules
efficience= output/input
MA= efficiency*velociyt ratio

Answer 2
