In a pulley system, can the force of friction equal the tension in the rope? Let's say there is a mass on a table connected to a pulley system (placed at the corner of the table), while the other mass hangs from the table ... can the force of friction equal the tension? Because I need to find the mass of the object hanging.

if the mass of the object on the table is m = 15 kg, the static friction coefficient is 0.75 and g= 9.8

  • Physics -

    Is the system moving?

    If it is not moving, then yes, the force of friction is exactly equal to the weight of the hanging object.

    But it makes no sense to give this type of question.

    forcefriction (max)= mg*mu.

    so, if it is stationary, then the hanging mass weight is equal or Less than this.
