Answer

The velocity ratio of a single fixed pulley is 1. If the point of application of effort E moves a distance d, then the load L also moves the same distance d upwards.

i.e. if d_E = d_L = d then V.R. = 1

$V.R. = \dfrac{d$

$\eta = 1 - \dfrac{w}{nE}$
$\eta = 1 + \dfrac{w}{nE}$
$\eta = \dfrac{w}{nE}$
$\eta = n - \dfrac{w}{E}$
