Question

A foroe of 730 N, applied parallel to the inclined plane
is required to move up a load of 900 N on the inclined
plane. If coefficient of friction is 0.25, determine the
inclination of the plane with horizontal

Answer 1

Step-by-step explanation:

Coefficient of friction is given as μ=0.25

Frictional force acting on the block f=μmg cosθ

Gravitational force acting along the inclined plane is mg sinθ

For no sliding, f=mg sinθ

∴ μmg cosθ =mg sinθ

⟹ tanθ=μ=0.25=
