91. A tightrope walker is walking between two buildings using a 15.0-m-long, 18.0-kg pole for balance (Figure 9-64). The daredevil grips the pole with each hand 0.600 m from the center of the pole. A 0.540-kg bird lands on the very end of the left-hand side of the pole. Assuming the daredevil applies forces with each hand in a direction perpendicular to the pole, how much force must each hand exert to counteract the torque of the bird? The + axis points in the walking direction, through the center of the pole. What are the directions of the torque vectors due to the bird, the left hand, and the right hand? Example 9-16 >

4. Orin and Ann, two paramedics, rush a 60.0 kg man from the scene of an accident to a waiting ambulance, carrying him on a uniform 3.00 kg stretcher held by the ends. The stretcher is 2.60 m long and the man’s center of mass is 1.00 m from Ann. How much force must Orin and Ann each exert to keep the man horizontal? a. Orin = 230 N, Ann = 388 N b. Orin = 201 N, Ann = 411 N c. Orin = 241 N, Ann = 377 N d. Orin = 141 N, Ann = 477 N e. None of the above
