A Foucault pendulum to show the rotation of the earth
A G-clamp with a ball bearing soldered to the inside of the jaw makes a excellent support for a Foucault Pendulum. It is top hung indoors with the ball bearing resting on a stout razor blade or some other hard surface. When this type of pendulum is set in motion, the plane of swing is changed after a few hours, as will be noticed if a mark is made on the ground at the time of release. It is, of course, the earth rotating underneath the 'bob' which gives this effect.
Calculating unknown resistances The current through the galvanometer (G) - a very sensitive ammeter, is reduced to zero by adjusting R 4 . The bridge is then said to be balanc
