At 20 c, a steel rod of length 40.000 cm and a brass rod
oflength 30.000 cm, both of the same diameter, are placed end to
endbetween two rigid supports 70.000 cm apart, with no initial
stressin the rods. the temperature of the rods is now raised to
60c. (a) what is the stress (the same in both rods) at 60 c. (b)
howfar from its old positioin is the new junction between
therods?
