1. A rod, a right triangle and a square are located in the x-y coordinate system. Their exact positions and masses are shown. Determine the exact (x,y) position for the center of gravity for this three- object system. y(m) 6.00 kg (9,7) (2,7) (-5,5) (8,5) 5.00 kg 5.00 kg (-2,2) (4,1) tm) 2. A uniform, horizontal beam of length 8.00m and weigl 200.0 N is attached to a wall by a pin connection. The far end of the beam is supported by a cable that makes an angle of 53.0 to the beam. A 600.ON person stands 2.00 m from the wall. Find: a) The tension in the cable b) The magnitude and direction of the total reaction force at the pin. 53.07 8.00 m
