A brass rod and a lead rod each 80 cm long at 0^@C are clamped together at one end with their free ends coinciding. The separatioin of free ends of the rods if the system is placed in a steam bath is ( alpha_("brass")=18xx10^(-6)//^(@)C and alpha_("lead")=28xx10^(-6)//^(@)C )

A brass rod and a lead rod each 80 cm long at 0^@C are clamped together at one end with their free ends coinciding. The separatioin of free ends of the rods if the system is placed in a steam bath is ( alpha_("brass")=18xx10^(-6)//^(@)C and alpha_("lead")=28xx10^(-6)//^(@)C )

A brass rod and a lead rod each 80 cm long at 0^@C are clamped together at one end with their free ends coinciding. The separatioin of free ends of the rods if the system is placed in a steam bath is ( alpha_("brass")=18xx10^(-6)//^(@)C and alpha_("lead")=28xx10^(-6)//^(@)C )

A brass rod and a lead rod each 80.00 cm long at 0^@C are clamped together at one end with their free ends coinciding. The separation of the free ends of the rods it the system is placed in steam bath is (coefficients of linear expansions of brass and lead are 2xx10^(-5)//^@C and 1.0 xx 10^(-5)//^@C respectively)

Due to rise in temperature of a brass rod by 100^(@)C , its length increases by 0.5 cm. What was the initial length of the rod? alpha for brass =19 times 10^(-6@)C^(-1) .

A brass rod of length 1 m is fixed to a vertical wall at one end, with the other end keeping free to expand. When the temperature of the rod is increased by 120^@C , the length increases by 3 cm . What is the strain?

A brass rod of length 1 m is fixed to a vertical wall at one end, with the other end keeping free to expand. When the temperature of the rod is increased by 120^@C , the length increases by 3 cm . What is the strain?

The temperature gradient in a rod of 0.5 m long is 80° C/m. IF the temperature of hotter end of the rod is 30°C, then the temperature of the cooler end is

A steel rod when measured with a zinc scale (alpha = 26 xx 10^(-6)//^@C) appears to be 1 m long when both rods are at 20^@C . If the zinc scale was graduated at 0^@C , what is the true length of the steel rod at 0^@C ? alpha for steel = 12 xx 10^(-6)//^@C .
