What is the formula for velocity ratio of a simple wheel and axle?
Besides, what is the formula of velocity ratio?
Velocity Ratio=d'÷d. A measure of the force amplification available with the system is the velocity ratio, or the ratio of the velocity (VF) with which the operator pulls the rope at F to the velocity at which the weight W is raised (V^W).
Then, what is velocity ratio of a simple machine?
Velocity ratio of simple machine is the ratio of distance travelled by effort to the distance travelled by load in the machine. The efficiency of a simple machine is defined as the ratio of useful work done by machine (output work) to the total work put into the machine (input work).
A simple mechanical lever with fulcrum is nothing but the simple machine. Another term is involved in the simple machine that is velocity ratio which is simply the ratio of the distance by which effort moves to the distance by which load moves.
