A bolt is passed through a pipe and a nut is just tightened. Coefficients of linear expansion for bolt and pipe material are `alpha_(b)` and `alpha_(p)` respectively. If the assembly is heated then:

A

A tensile stress will be induced in the bolt if `alpha_(b)ltalpha_(p)`

B

A compresive stress will be induced in the bolt if `alpha_(b)ltalpha_(p)`

C

A compressive stress will be induced in the bolt is `alpha_(b)=alpha_(p)`

D

No stress will be iduced in the bolt if `alpha_(b)gt alpha_(p)`
