SSC SSC JE Mechanical 2025 Mock Test Series (Paper 1 & Paper 2) Engineering Mechanics Equilibrium and Friction Friction
A body of weight 100 N is placed on a rough horizontal plane as in Figure, requires a pull of 40 N inclined at 30 degrees to the horizontal, just to move it. Determine the co-efficient of friction between the block and horizontal plane. (take cos 30 = \({\sqrt3\over 2}\); sin 30 = 0.5)
