The free body diagram shows the normal force and the force of static friction acting on the ladder at the ground. The last diagram shows the lever arms for the forces. Solve using only variables. How long can you climb the ladder before the ladder slips? Do you think the ladder starts to slip immediately? (Solve for x assuming the formula μs = 1/2 * tangent θ)
