Homework Help: Pendulum force

  1. Sep 25, 2007 #1
    I'm having trouble with the idea of tension in a pendulum. I've reasoned out my answers, but they're wrong. Am I missing a concept completely or am I overlooking a detail?
    The problem statement, all variables and given/known data

    The following questions deal with a pendulum in motion with angle not being its extreme end where v = 0 m/s

    1. T is smallest when angle= ± angle not

    False at the extremes the Tension is at a maximum

    2. The vertical component of tension is constant.

    False the vertical component is always changing due to the change of position

    3. T = Mg at some angle between zero and angle not.

    True this should occur at 0 degrees

    4. T is greater than Mg when angle=angle not

    True T = T + mg

    5. T is largest at the bottom (angle=0)

    False T is largest at the pendulums extremes

    6. T equals Mg when angle = angle not

    False T = T +mg
