Question

θ^e=\(\frac{E_eA_el_e\alpha\Delta T}{x_2-x_1}\begin{Bmatrix}-1 \\ 1  \end{Bmatrix}\)  is the temperature effect.

(a) True

(b) False

The question was posed to me in unit test.

This interesting question is from One Dimensional Problems topic in portion One Dimensional Problems of Finite Element Method

Answer 1

Right option is (a) True

For explanation: Temperature is the measure of average kinetic energy of the particles in a system. Adding heat to system causes its temperature to rise. Temperature effect describes that how much of temperature is rised in body when load is applied. Temperature effect formula is as shown

θ^e=\(\frac{E_eA_el_e\alpha\Delta T}{x_2-x_1}\begin{Bmatrix}-1 \\ 1  \end{Bmatrix}\).
