Question: An initially straight beam of length L = 3 m and constant bending stiffness of EI = 10 000 Nm2 is heated on the top

An initially straight beam of length L = 3 m and constant bending stiffness of EI = 10 000 Nm2 is heated on the top to 30 C above and cooled on its bottom by 30 C below its reference temperature. We shall assume a linear distribution of temperature over the height of the beam, as well as a known constant linear coefficient of thermal expansion, = 1.0105 K1. The cross section is rectangular with a width of B = 10 cm and height of H = 25 cm
