sl = distance moved by the load (m, ft)
The efficiency of a simple machine is defined as the ratio of the force ratio to the movement ratio and can be expressed as
μ = Fr / Mr (2)
μ = machine efficiency
Fr = force ratio
Motion - velocity and acceleration, forces and torque.
Forces, acceleration, displacement, vectors, motion, momentum, energy of objects and more.
The connecting rod mechanism.
The force ratio is the load force versus the effort force.
Pulley (Sheave) selection charts for motors ranging 850 - 3450 rpm.
