Two rods of different materials with coefficients of thermal expansion
α1 and
α2 respectively; Young's moduli
Y1 and
Y2 respectively; of initial lengths
l1 and
l2 respectively of equal cross-sectional areas are joined at one end. The free ends are fixed to two vertical walls as shown in figure.
Temperature of the surrounding is then increased by
T∘C. Find out the displacement of the joint of the rods.
