    Motion of simple pendulum.

    The diagram shows a simple pendulum consisting of a mass M = 1.25 kg suspended by a thin string with a length of l = 0.910 m. The mass swings back and forth between ±q0. T is the magnitude of the tension in the string.

    1) True or false
    T depends only on q. {q is for theta}
    The vertical component of tension is constant.
    T=Mg at some angle between zero and q0.
    T is greater than Mg for q = q0.
    T is largest at the bottom (q = 0).
    T equals Mg when q = q0.
    T is smallest when q = ±q0.

    2) If q0 = 52.3°, find the maximum kinetic energy of the mass during an oscillation.

    3) Find the magnitude of the tension when the angle q = q0 = 52.3°.

    4) Find the magnitude of the tension when the angle q = 0.0°.

    Please show me how to solve such a problems. Having hard time understanding harmonic motion

    Solution Summary

    A pendulum swings with large angles. Some true false, and then problems with tension in the string in different situations are solved.
