12.23. Model: The beam is a solid rigid body. Visualize:The steel beam experiences a torque due to the gravitational force on the construction worker()GCFGand the gravitational force on the beam ()GB.FGThe normal force exerts no torque since the net torque is calculated about the point where the beam is bolted into place. Solve:The net torque on the steel beam about point O is the sum of the torque due to ()G
