A rod of length l and area of cross-section A is heated from `0^(@)C` to `100^(@)C`. The rod is so placed that it is not allowed to increase in length, then the force developed is proportional to

The temperature of a wire length 1 m and area of cross-section 1 cm^(2) is increased from 0^(@)C to 100^(@)C . If the rod is not allowed to increase in length, then the force, required will be (alpha = 10^(-5) .^(@)C^(-1) and Y = 10^(11) Nm^(-2) )

An iron bar of length and having a cross section A is heated from 0 to 100^@C . If this bar is so held that it is not permitted to expand or bend, the force that is developed, is

An iron of length l and having cross-section A is heated form 0^(@)C to 100^(@) C. IF his bar is held so that it is not permitted to expand or bend, the gigantic force that is developed is

An iron bar of length I and having a cross-section area A is heated from 0^(@) to 100^(@)C . If this bar is so held that it is not permitted to expand or bend, the force that is developed, is

The temperature of a rod of length 1 meter and area of cross-section 1 cm^(2) is increased from 0^(@)C to 100^(@)C . If the rod is ot allowed to increase in length, the force required will be: (alpha=10^(-6)//""^(@)C and Y=10^(11)N//m^(2))

The temperature of a wire of length 1 metre and area of cross-section 1 cm^(2) is increased from 0^(@)C to 100^(@)C . If the rod is not allowed to increased in length, the force required will be (alpha=10^(-5)//.^(@)C and Y =10^(11) N//m^(2))

The temperature of a wire of length 1 metre and area of cross-section 1 cm^(2) is increased from 0^(@)C to 100^(@)C . If the rod is not allowed to increased in length, the force required will be (alpha=10^(-5)//.^(@)C and Y =10^(11) N//m^(2))

A steel rod (Y = 2.0xx10^(11) N//m^(2) and alpha = 10^(-50) .^(0)C^(-1) ) of length 1m and area of cross-section 1cm^(2) is heated from 0^(@)C to 200^(@)C without being allowed to extended or bend. Then the tension produced in the rod is

An iron bar of length L . Cross section A and Young's modulus Y is heated from o^(o)C to 100^(0)C . If this bar is held so that it is not permitted to bend and to expand, the force F that is develop, is proportional to
