A steel beam being used in the construction of a skyscraper has
a length of 39.000 m when delivered on a cold day at a temperature
of 11.000°F. What is the length of the beam when it is being
installed later on a warm day when the temperature is 89.000°F?
(Give your answer to at least five significant figures.)

A crane at a construction site is used to lift and move steel
beams and place them on the building under construction as needed.
The motion of the beam is measured tension in the cable and the
time intervals the tension is applied.
For example, consider the following situation:
The beam is initially suspended, stationary, above the ground.
The tension in the cable is T0 = 2580 N.
Next, the tension in the cable is T1 = 2660 N for...
