This force is labeled Ff v in the picture. FN Assume that the ladder's weight is evenly distributed, so it can be treated as a single force through the middle. If the ladder is at a 70° angle from the ground, what is the torque exerted by the weight (using the floor as the pivot point)? N.m The torque from the ladder must be balanced by the torque caused by the normal force on the wall, labeled Fw in the picture. Calculate this force.
