A composite member shown below was formed at 20°C and was made of two materials A & B. If the coefficient of thermal expansion of A is more than that of B and the composite member is heated to 140°C, then
1
A will be in tension and B in compression
2
Both A and B will be in compression
3
A will be in compression and B in tension
4
Both A & B will be in tension
