Chapter 7, Problem 36P
Figure P7.36 shows two thin beams joined at right angles. The vertical beam is 15.0 kg and 1.00 m long and the horizontal beam is 25.0 kg and 2.00 m long.
Figure P7.36
a. Find the center of gravity of the two joined beams. Express your answer in the form (x, y), taking the origin at the corner where the beams join.
b. Calculate the gravitational torque on the joined beams about an axis through the corner. The beams are seen from the side.
