Figure 5-53 shows a man sitting in a bosun's chair that danglesfrom a massless rope, which runs over a massless, frictionlesspulley and back down to the man's hand. The combined mass of manand chair is 83.9 kg. With what force magnitude must the man pullon the rope if he is to rise (a) with a constant velocity and (b)with an upward acceleration of 1.40 m/s2? (Hint: A free-bodydiagram can really help.) Problem continues below.

A man in a bosun chair dangles from a massless rope, which runsover a massless, frictionless pulley and back down to the man'shand. Combined mass of the man and chair is 95.0 kg. What forcemust the man pull on the rope if he is to rise (a) with constantvelocity and (b) with an upward acceleration of 1.3m/s2? The same man in the bosun chair dangles from amassless rope, which runs over a massless, frictionless pulley andback down to a man standing on the ground, pulling therope. What force magnitude must the man on the groundpull for the man in the bosun chair to rise (c) with a constantvelocity and (d) with an upward acceleration of 1.3m/s2? What is the magnitude of the force on the ceilingfrom the pulley system in (e) part a, (f) part b, (g) part c, and(h) part d.

I would appreciate help with any of the following problems. Thankyou.

22. In an isometric exercise a person places a hand on a scale andpushes vertically downward, keeping the forearm horizontal. This ispossible because the triceps muscle applies an upward forceperpendicular to the arm, as the figure indicates. The forearmweighs 22.1 N and has a center of gravity as indicated. The scaleregisters 113 N. Determine the magnitude of .
Distance between the force applied by the muscle and the elbowjoint 0.025 m. The distance between the elbow joint and the armscenter of gravity is 0.15 m. Distance between the arms center ofgravity and the center of the scale is 0.15 m. I was not able tofind the answer to this problem using the solution posted on thewebsite.

26.A wrecking ball (weight = 4310 N) is supported by a boom, whichmay be assumed to be uniform and has a weight of 2550 N. As thedrawing shows, a support cable runs from the top of the boom to thetractor. The angle between the support cable and the horizontal is32°, and the angle between the boom and the horizontal is 48°. Find(a) the tension in the support cable and (b) the magnitude of theforce exerted on the lower end of the boom by the hinge at pointP.

56. Two identical wheels are moving on horizontal surfaces. Thecenter of mass of each has the same linear speed. However, onewheel is rolling, while the other is sliding on a frictionlesssurface without rolling. Each wheel then encounters an inclineplane. One continues to roll up the incline, while the othercontinues to slide up. Eventually they come to a momentary halt,because the gravitational force slows them down. Each wheel is adisk of mass 3.64 kg. On the horizontal surfaces the center of massof each wheel moves with a linear speed of 5.26 m/s. (a),(b) Whatis the total kinetic energy of each wheel? (c), (d) Determine themaximum height reached by each wheel as it moves up the incline. Iwas able to solve for the rolling wheel but couldn't find the rightanswers for the sliding wheel.

66. A thin uniform rod is rotating at an angular velocity of 1.89rad/s about an axis that is perpendicular to the rod at its center.As the figure indicates, the rod is hinged at two places,one-quarter of the length from each end. Without the aid ofexternal torques, the rod suddenly assumes a "u" shape, with thearms of the "u" parallel to the rotation axis. What is the angularvelocity of the rotating "u"?

76. A woman who weighs 501 N is leaning against a smooth verticalwall, as the drawing shows. Find (a) the magnitude of the force N(directed perpendicular to the wall) exerted on her shoulders bythe wall and the (b) horizontal and (c) vertical components of theforce exerted on her shoes by the ground.
