Question

what is a practical machine?what is the relation between MA and VR in a practical machine​

Answer 1

Answer:

M.A = V.R x efficiency..

Answer 2

Answer:

Efficiency

Explanation:

Mehanical Advantage / velocity Ratio. For ideal machine efficiency = 1. Hence M.A = V. R. ... R of an ideal machine and the practical machine is a constant or is the same for both.
