Teaching HPSC Lecturer (Technical) Mock Test 2024 Engineering Mechanics Equilibrium and Friction Equilibrium
A wooden block of weight 50√2 rests on a horizontal plane. If a push force (P) at an angle of 45° to the horizontal (as shown in Figure) is enough to cause the impending motion of the block. Determine the magnitude of force. [Coefficient of friction between the surfaces = 0.4]
