Question

Q18. Efficiency of a machine in terms of mechanical advantage(
MA) and velocity ratio(VR) is given by
(A) V.R/
MA
(B) 1/VR)X(M.A)
(C) M.A÷V.R
(D) MA+VR​

Answer 1

Answer:

The Correct Relationship Between the Mechanical Advantage (M.A), the Velocity Ratio (V.R) and the Efficiency (N) Is: (A) M.A. ... (B) V.R. = η × M.A.
