Calculate the net torque about O at P, assuming that a 50-kg mass is attached at P, F = 35 N and θ = 30° (see figure below). The force  Fg due to gravity on a mass m has magnitude 9.8m m/s2 in the downward direction. (Round your answer to two decimal places.)

The torque about the origin O due to a force F acting on an object with position vector r is the vector quantity t = rx F. If several forces F; act at positions ri, then the net torque (units: N-m or Ib-ft) is the sum Torque measures how much the force causes the object to rotate. By Newton's Laws, T is equal to the rate of change of angular momentum. The torque about the origin O due to a force F acting on an object with position vector r is the vector quantity t = rx F.
