1. The problem statement, all variables and given/known data Suppose a steel strut with cross-sectional area 7.00x10^-4 m2 and length 2.50 m is bolted between two rigid bulkheads in the engine room of a submarine. (a) Calculate the change in temperature of the strut if it absorbs an energy of 3.00x10^5 J. °C 2. Relevant equations Q = mcDeltaT DeltaT = Q/mc 3. The attempt at a solution I tried using the formula DeltaT = Q/mc Delta T = 3.00 x 10^5/ m(448 J/kg *C) the problem im having is how do i find the mass?
