The figure shows a bar in equilibrium position resting on the floor at point A and on the wall at point B. If the mass of the bar is m and the angle it makes with the floor is θ = π/6, find the magnitudes of the frictional and normal forces at points A and B.

The uniform box shown in next figure, has a mass of 40 Kg. If the two forces T 60 N and F 30 N are applied on the box, determine if it remains in equilibrium. The coefficient of static friction (u) = 0.24 F=30N T=60N 30 40 Kg
