3. The window washers A and B support themselves and the horizontal, uniform platform CD (i.e. the weight of the platform acts at its centre) by pulling down on the two ropes. The pulling force on the rope by the washer B is 567 N. The mass of washer A is 77 kg. Determine the tension in the rope connected at C, the mass of the washer B and the force that each man exerts on the platform. 13.5 kg 3 m 77 kg A 0.6 m B 1.2 m D
