7. Joe, a pole-vaulter, is holding a vaulting pole parallel to the ground. The pole is 5 m long. Joe grips the pole with his right hand 10 cm from the top end of the pole and with his left hand 1 m from the top end of the pole. Although the pole is light (its mass is only 2.5 kg), the forces that Joe must exert on the pole to maintain it in this position are large. How large...

Torque question: An essentially weightless shovel is 120 cm long. Someone holds it horizontally, supporting it with his left hand at the shovel's center of gravity and his right hand 80.0 cm to the right of the c.g. The shovel contains a 20 N rock whose cg is 8 cm to the right of the edge of the shovel. How much force does the person exert down on the handle? Answer is supposed to be 8 N but I'm having...
