Thank you! so the normal force of the ground on the ladder(Ng) is equal to the gravitational force (Fg). so Fg= Ng and the friction force(Ff) is equal to the normal force of the wall on the ladder Nw. so Ff = Nw to get the torque, knowing that τ= 1/2 r F and solving about the point...

Homework Statement A uniform 7.7 m tall aluminum ladder is leaning against a friction-less vertical wall. The ladder has a weight of 291 N. The ladder slips when it makes a 59.0◦ angle with the horizontal floor. Determine the coefficient of static friction between the ladder and the floor...
