a machine displaces a load of 125kgf through a distance 0.30m, when an effort of 12.5 kgf acts through a distance of 4.0m. Calculate a). velocity ratio b). mechanical advantage c).percentage efficiency of the machine.
Please send it fast. It is urgent

Dear student,Given values areL = 125Kgfd=0.30mE=12.5KgfD=4.0mA.VELOCITYRATIO =DdVelocity ratio =4.00.3Velocity ratio=13.3B.MECHANICAL ADVANTAGE=LOADEFFORTMechanical advantage=12512.5Mechanical advantage=10C.EFFICIENCY PERCENTAGE=MECHANICAL ADVANTAGEVELOCITY RATIO×100%Efficiency percentage=1013.33×100%Efficiency percentage=75.01%
