Asked by Lynn
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?

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