An old wooden telephone pole with a single cross member was blown off center during a recent storm. To temporarily stabilize the telephone pole, a repair crew has attached a cable from the end of the cross member to an eye-ring stake anchored in the ground. (Figure 3) If the origin O of a coordinate system is placed where the pole meets the ground, the point where the cross member is attached to the pole is A(?1.00,1.35,11.5)m and the point...

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...
