Questions
Pushing force making an angle to the horizontal is applied on a block of weight w placed on a horizontal table. If the angle of friction is , the magnitude of force required to move the body is equal to
detailed solution
Correct option is B
N=w+Fsinθ∴ fmax=μN=(tanϕ)(w+Fsinθ)To move the body, Fcosθ=fmax=(tanϕ)(w+Fsinθ)Solving this equation, we getF=wsinϕcos(θ+ϕ)Talk to our academic expert!
