Suppose a steel strut having a cross-sectional of area 4.00 10-4 m2 and length 2.80 m is bolted between two rigid bulkheads in theengine room of a submarine. Assume the density of steel is the sameas that of iron.
(a) Calculate the change in temperature of thestrut if it absorbs an energy of 3.00 105 J.
°C
(b) Calculate the compressional stress in the strut.
