Question
A block of mass m lying on a rough horizontal plane is acted upon by a horizontal force P and another force Q inclined an at an angle θ to the vertical. The minimum value of coefficient of friction between the block and the surface for which the block will remain in equilibrium is:
Options
A.
B.
C.
D.
Solution
N = mg + Q cos θ
P + Q sin θ ≤ μN
⇒ μ ≥
