Use the worked example above to help you solve this problem. A steel strut near a ship's furnace is 1.80 m long, with a mass of 1.59 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 105 j. (a) Find the change in temperature of the strut. ос (b) Find the increase in length of the strut. 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.
