A pulley is holding two masses-0.5 kg and 2.0 kg. The system is in static equilibrium; the pulley is frictionless; the string is massless.

What is the tension of the string holding the pulley?

  • Physics -

    If the system is in static equilibrium, there is no motion for any of the items.

    So the tension of the string holding the pulley is
    Σmass*acceleration due to gravity
    =(0.5kg+2.0kg+0kg(string)+mass of pulley)*g
    =(2.5kg+mass of pulley)*g
