(a) The velocity ratio of the screw is 1570.8.

(b) The mechanical advantage of the screw is 785.39.

Velocity ratio of the screw

The velocity ratio of the screw is calculated as follows;

V.R = 2πr/P

where;

  • P is the pitch = 1/10 cm = 0.1 cm = 0.001 m
  • r is radius = 25 cm = 0.25 m

V.R = (2π x 0.25)/(0.001)

V.R = 1570.8

Mechanical advantage of the screw

E = MA/VR x 100%

0.5 = MA/1570.8

MA = 785.39
