Q. A massless scaffold (beam) is held up by a wire at each end. The scaffold is 12 m long. A 300-N box sits 4.0 m from the left end. What is the tension in each wire?
Q. A wrench 0.3 meters long lies along the positive y-axis, and grips a bolt at the origin. A force is applied in the direction of langle 0, 1, 2rangle at the end of the wrench. Find the magnitude of the force in newtons needed to supply 100 newton-meters of torque to the bolt.
