A ladder of length 2L and mass M is positioned on level ground leaning against a wall such that the angle between the ladder and the horizontal is @. The coefficient of static friction between the ladder and the wall and between the ladder and the ground is jistatic = 0.66. The centre of mass of the ladder is halfway along it. For the ladder to be in mechanical equilibrium: Consider torques about the centre of the ladder. In which direction (into or out of the page) does the torque due to each of the 5 forces force act?Write down an equation for the sum of the torques about the centre or mass of the ladder and then use your equation for the torques to derive an expression for tan o in terms of the magnitudes of the forces acting
