What should be the lengths of steel and copper rods so that the length of copper?

The lengths of steel and copper rods are so that the length of the steel rod is 5 cm longer than that of the copper rod at all temperatures, then length of each rod, are. (α for copper =1. 7×10−5per∘C and α for steel =1. 1×10−5per∘C).

What is the length of brass and iron at 0 degrees Celsius?

The value of a for brass and iron are 18×10″/C and 12×10″/C” respectively.

What should be the length of steel and copper rod at 0 C?

A steel tape measures the length of a copper rod as 90.0 cm, when both are at 100C, the calibration temperature, for the tape.

What should be the sum of lengths of an Aluminium and steel rod at 0 degree Celsius?

According to the question the change in length at all temperatures is the same. Therefore, the sum of length of both rods at \[{0^ \circ }C\] is \[0.75m\].

What is the length of brass?

Pitch of brass instruments

What is the long copper rod called?

Explanation:the long copper rod is called lightning rod. Lightning rods are designed to protect a building from the damage that a direct lightning strike can cause. Unprotected buildings can experience electrical fires as the current travels across any conductive materials that exist.

What is coefficient of linear expansion?

The coefficient of linear expansion is the change in length of a specimen one unit long when its temperature is changed by one degree (see linear expansion). Different materials expand by different amounts. If these forces are strong, the material can only expand slightly for a given rise in temperature.

How do you calculate the average coefficient of linear expansion?

Linear thermal expansion is ΔL = αLΔT, where ΔL is the change in length L, ΔT is the change in temperature, and α is the coefficient of linear expansion, which varies slightly with temperature.

What is the difference between copper and brass?

Copper is a base metal, while brass is an alloy. As a base metal, copper holds a place on the periodic table of elements. Copper is found naturally in the state that it is in, while brass is not. It is a combination of copper and zinc.

What is the difference between alpha brass rod and steel rod?

A brass rod and a steel rod are both measured at 0^∘ C. Their lengths are found to be 150 cm and 150.2 cm respectively. At what common temperature will their lengths be equal? ( alpha steel = 12 × 10^-6 /^∘ C, alpha brass = 18 × 10^-6 /^∘ C)

What is the correct length of a brass rod at 30^∘C?

A brass rod at 30^∘C is observed to be 100 cm long when measured by a steel scale which is correct at 0^∘ C . alpha for steel is 12 × 10^-6/^∘C and alpha for brass is 19 × 10^-6/^∘C . The correct length of brass rod at 0^∘C is : > A brass rod at 30^∘C is obs…

What is the length of a copper rod at all temperatures?

A copper rod and a steel rod maintain a difference in their lengths constant= 10 cm at all temperatures. If their coefficients of expansion are 1.6×10 −5K −1 and 1.2×10 −5K −1, then the length of the Cu rod is

What is the coefficient of expansion for a copper rod?

A copper rod and a steel rod maintain a difference in their lengths constant = 10 cm at all temperatures. If their coefficients of expansion are 1.6 × 10^-5 K^-1 and 1.2 × 10^-5 K^-1, then the length of the Cu rod is Class 11
