The velocity ratio of an inclined plane where angle of inclination in θ is
A.
Sinθ
B.
Cosθ
C.
Tanθ
D.
1sinθ
Correct answer is D
Consider an inclined plane shown below, as the effort moves along OB, the load moves is lifted up through a vertical height AB
V.R = distance moved by effortdistance moved by load = OBAB
But Sinθ = opphyp = ABOB
therefore; = OBAB = 1sinθ
