QUESTION 2 / VRAAG 2 [4] The drawing shows box 1 resting on a table, with box 2 resting on top of box 1. A massless rope passes over a massless, frictionless pulley. One end of the rope is connected to box 2, and the other end is connected to box 3, which is hanging from the rope. The weights of the three boxes are Wi = 55 N, W2 = 35 N, and W3 = 28 N. Calculate the magnitude of the 3 normal force that the table exerts on box 1. Die tekening dui boks I can wat op'n tafel rus, met'n boks 2 bo -op boks 1. 'n Massalose, wrywinglose tou loop oor'n wrywinglose katrol: die tou se een eindpunt is aan boks 2 vasgemaak, en die ander aan boks 3, wat van die tou hang. Die bokse se gewigte is soos volg: W1 = 55 N, W2 = 35 N, en W3 = 28 N. Bepaal die normaalkrag wat die tafel op boks 1 vitoefen. /4)
