A 22.0-m-long bar of steel expands due to a temperature
increase. A 11.0-m-long bar of copper also gets longer due to the
same temperature rise. The two bars were originally separated by a
gap of 1.6 cm. Assume the steel and copper bars are fixed on the
ends, as shown in the following figure.
1)
Calculate the change in temperature if the gap is exactly
"closed" by the expanding bars. (Express your answer to two
significant figures.)

A lamp of mass M is hung off of a steel bar of mass m and length / (treat as known). The bar makes a M450 60° angle with the vertical wall. In order to prevent the steel bar from bending or snapping, a cable is hung off of the wall that connects at the end of the bar. The cable creates a 45° angle with the vertical wall. 60° a) Draw an extended free body diagram (not for a...
