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?

To find the strain in the brass rod, we can follow these steps: ### Step 1: Understand the given information - The original length of the brass rod (L) = 1 meter = 100 cm (since we will convert everything to centimeters for consistency). - The change in length (ΔL) = 3 cm. - The change in temperature (ΔT) = 120 °C (not directly needed for strain calculation but relevant for understanding thermal expansion). ### Step 2: Recall the formula for strain ...

Two rods of equal cross sections, one of copper and the other of steel, are joined to form a composite rod of length 2.0 m at 20^@C , the length of the copper rod is 0.5 m. When the temperature is raised to 120^@C , the length of composite rod increases to 2.002m. If the composite rod is fixed between two rigid walls and thus not allowed to expand, it is found that the lengths of the component rods also do not change with increase in temperature. Calculate Young's moulus of steel. (The coefficient of linear expansion of copper, alpha_c=1.6xx10^(-5@)C and Young's modulus of copper is 1.3xx10^(13)N//m^(2) ).
