Physics, asked by bijitdeka353, 10 hours ago

The law of a machine is given by the relation :P = 0.04 W + 7.5where (P) is the effort required to lift a load (W), both expressed in newtons. What is the mechanical advantage and efficiency of the machine, when the load is 2 kN and velocity ratio is 40 ? What is the maximum efficiency of the machine ?If (F) is the effort lost in friction, find the relation between F and W. Also find the value of F,when W is 2 kN
