Define mechanical advantage (M.A.) and velocity ratio (V.R.) of machine. |
|
Answer» Mechanical advantage: The ratio between load and effort is called mechanical advantage (M.A.): M.A. = Load(L)/Effort(E) It has no unit. Velocity ratio: The ratio between displacement of effort and displacement of load is called Velocity ratio (V.R.): V. R. = dE/dL Where dE and dL are the displacement of effort and load respectively in time t. |
