Q1:

A body of weight W is required to move up the rough inclined plane whose angle of inclination with the horizontal is α. The effort applied parallel to the plane is given by (where μ = tan φ = Coefficient of friction between the plane and the body)

A P = W tan α

B P = W tan (α + φ)

C P = W (sin α + μ cos α)

D P = W (cos α + μ sin α)

ANS:C - P = W (sin α + μ cos α)
