The figure shows a rigid bar A B C pinned at A and supported at B by a wire labeled 1 of length 600 millimeters. The separation between A and B is 400 millimeters and the separation between B and C is 800 millimeters. A weight W is shown attached to the bar at C. The parameters listed on the top left are A subscript 1 which equals 2 square millimeters, E subscript 1 which equals 200 giga pascals and alpha subscript 1 which equals 12 times 10 to the negative 6 per degree Celsius.

A rigid bar $ABC$ is pinned at $A$ and supported by a steel wire at $B$ . Before weight $W$ is attached to the rigid bar at $C$ , the rigid bar is horizontal.
