1. Weights of 2, 4, 6 and 8 N are fastened to the corners of a 2 m x 2 m frame. If it weighs 10 N, where would the fulcrum (the support point) be placed to balance the frame and the weights? 2. A ladder 12 m long leans against a vertical frictionless wall with its lower end 3 m from the wall. The ladder weighs 40 N. Find the magnitude and direction of the force exerted on the lower end of the ladder
