Clock pendulums are made of invar
Did you know?
WebInvar is an alloy which has a small coefficient of linear expansion. The length of a pendulum made of invar does not change with temperature and hence the time period of oscillation remains the same. Hence the time shown by the clock is accurate. Suggest Corrections. 4. WebBeginning around 1900, some of the highest precision scientific clocks had pendulums made of ultra-low-expansion materials such as the nickel steel alloy Invar or fused silica, which required very little compensation for the effects of temperature.
