Mechanical advantage (M. A), load (L) and effort (E) are related as :
(a) M.A = L × E (b) M.A. × E = L
(c) E= M.A. × L (d) none of these.
The correct relationship betwen the mechanical advantage (M.A.), the velocity ratio (V. R.) and the efficiency η is :
(a) M.A=η×V.R. (b) V.R=η×M.A
(c)η=M.A×V.R (d) none of these.
