DETERMINATION OF THE RESULTED LENGTH OF PHYSICAL PENDULUM

Purpose of work: study of laws of oscillation physical and mathematical pendulums.

Task: experimentally and theoretically to find resulted length of physical pendulum.

Devices and equipments: physical pendulum, mathematical pendulum, straightedge, stop-watch. The experimental setting (fig.10.1) consists of physical 1 and mathematical 2 pendulums.

Figure 10.1

Length of mathematical pendulum can be fluently changed, reeling it in 5 and to fix spirally 6.
