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

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 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

A metal rod has length of 100 cm and cross-section of 1.0 cm^(2) . By raising its temperture from 0^(@)C to 100^(@)C and holding it so that it is not permitted to expand or bend, the force developed is (Given Y=10^(12) dyne cm^(-2) and alpha=10^(-5) .^(@)C^(-1) )

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

An iron bar of length L and area of cross section A is heated from 10^circ C to 90^circ C , The bar is so held between supports that it is neither allowed to extend nor allowed to bend If the stress developed in the bar be S, then

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

When a metallic bar is heated from 0^(@)C to 100^(@)C its length increases by 0.05%. What is the coefficient of linear expansion of the metal?
