Use the worked example above to help you solve this problem. A steel strut near a ship's furnace is 1.75
m long, with a mass of 1.46 kg and a cross-sectional area of 1.00 x 10-4 m². During operation of the
furnace, the strut absorbs thermal energy in a net amount of 2.50 x 10³ J.
(a) Find the change in temperature of the strut.
380.52
°C
(b) Find the increase in length of the strut.
0.00741
m
(c) If the strut is not allowed to expand because it's bolted at each end, find the compressional
stress developed in the strut.
8.47e8
Your response is within 10% of the correct value. This may be due to roundoff error, or you could
have a mistake in your calculation. Carry out all intermediate results to at least four-digit accuracy
to minimize roundoff error. Pa
