A simple machine raises a load of 120 kg120 \mathrm {~kg} through a distance of 1.2 m1.2 \mathrm {~m} . The effort applied to the machine is 150 N150 \mathrm {~N} and moves through a distance of 12 m12 \mathrm {~m} . Taking g as 10 m/s210 \mathrm {~m} / \mathrm { s } ^ { 2 } , determine the force ratio, movement ratio and efficiency of the machine.
