Question

what is ?
(a) angular amplitude
(b) pendulum length

Answer 1

a)The angular amplitude is defined by the angle that the string makes vertical. The weight of the pendulum acts downward and it can be resolved into two components. The component Mg is equal in magnitude to the tension in the string.

b)Pendulum clocks should be attached firmly to a sturdy wall. The most common pendulum length in quality clocks, which is always used in grandfather clocks, is the seconds pendulum, about 1 metre (39 inches) long. In mantel clocks, half-second pendulums, 25 cm (9.8 in) long, or shorter, are used.
