The figure shows a vertical bar A B C D pinned at end A which is at the bottom. The vertical bar is supported by horizontal bars at B and D labeled 1 and 2 of lengths 550 millimeters and 750 millimeters respectively. The separation between A and B is 830 millimeters. The separation between B and C is 500 millimeters and the separation between C and D is 580 millimeters. A box at the bottom right of the figure lists the following bar properties. A subscript 1 equals 720 square millimeters, E subscript 1 equals 80 giga pascals, A subscript 2 equals 300 square millimeters and E subscript 2 equals 140 giga pascals.
