Should I multiply
elasticity of copper (N/m^2) by
cross-sectional area of the copper in the pipe (3 x 10-5 m^2)
multiple by the distance each tick the pipe moves
and divide by the distance of the pipe (5m)?
Well I have found that the typical value for the elastic modulus of copper is 1.1 x 10^11 Pa. Now I have length of the pipe which is 5 meters, Cross-sectional area of the copper in the pipe in m^2, how much it moves with each tick (18 ticks as well) and typical value of elasticity of copper in...
[b]1. When the hot water in a certain upstairs bathroom is turned on, a series of 18 "ticks" is heard as the copper hot-water pipe slowly heats up and increases in length. The pipe runs vertically from the hot-water heater in the basement, through a hole in the floor 5 m above the water heater...
