Checking Verticals and Finding a Centre of Gravity
Hang the line beside a retort stand rod, a pendulum support or the wires of Searle’s apparatus and sight along both from two directions at right angles: the part is vertical when it runs parallel to the line each time. To find the centre of gravity of a flat lamina, hang the lamina and the plumb line from the same pin and mark the line on the lamina; repeat from a second hole, and the centre of gravity is where the two lines cross.
