A bar of bronze and a bar of steel are placed between two immovable supports, A & B as shown in the figure. The physical constants are: (where L= length of bars, A = cross-sectional area, $$\alpha =$$ linear co-efficient of thermal expansion, E= Young’s modulus)

The stresses in the steel & bronze, when temperature drops by $$50^\circ C$$ is

A

Tension

B

Compression

C

Shear

D

None of these
