Suppose a steel strut with cross-sectional 5.00 x 10^-4m^2 and length 2.50m is bolted between two rigid?
REST OF THE PROBLEM...
Suppose a steel strut with cross-sectional 5.00 x 10^-4m^2 and length 2.50m 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 3.00 x 10^5j. (b) Calculate the compressional stress in the strut.
The book has an answer of (a) 68.2C and (b) 1.50 x 10^8.
PLEASE HELP ME I HAVE DONE THIS PROBLEM THREE TIME AND STILL DON'T UNDERSTAND HOW THIS ANSWER CAME ABOUT, PLEASE SHOW ME THANK YOU

You are missing a piece of information, and that is the specific heat density of the steel, i.e. the joules/m^3/kelvin. With this information, you would simply calculate the volume of steel you have in the beam, then divide the number of joules by the volume and joules*m^3/kelvin and it should give you the degrees change
