Part AIn order to prevent muscle contraction from misaligning bonesduring healing (which can cause a permanent limp), injured orbroken legs must be supported horizontally and at the same timekept under tension (traction) directed along the leg. One version ofa device to accomplish this aim, the Russell traction apparatus, isshown in (Figure 1). This system allows the apparatus to supportthe full weight of the injured leg and at the same time provide thetraction along the leg.If the leg to be supported weighs 41.0 N, what must be the weight of W?Express your answer in newtons.ΤΕΙ ΑΣΦ?Figure25°25°WW =SubmitPrevious Answers Request Answer× Incorrect; Try Again; 5 attempts remainingPart B1 of 1What traction force does this system produce along the leg?Express your answer in newtons.F =ΜΕ ΑΣΦSubmitPrevious Answers Request Answer?NN

A pile driver lifts a 250 kgkg weight and then lets it fall onto the end of a steel pipe that needs to be driven into the ground. A fall of 1.5 mm before striking the pipe drives the pipe in 40 cmcm. Part A What is the average force that the weight exerts on the pipe? (Hint: Let the weight be the system)
One of the hazards of prolonged weightlessness on long space missions is bone and muscle loss. To combat this problem, NASA is studying a human-powered centrifuge. In this device, one astronaut pedals a suspended, bicycle-like contraption, while a second astronaut rides standing up in a similarly suspended platform. Part A If the standing astronaut moves with a speed of 3.1 m/s at a distance of 3.2 m from the center of the device, what is the astronaut's centripetal acceleration? Give your answer as a multiple of g, the acceleration due to gravity on the surface of the Earth. Express your answer to two significant figures. να ΑΣφ. ? Submit Request Answer

In this assignment, the radius refers to the distance between the location where the force is applied and the axis of rotation. A ruler is initially at rest when a student briefly exerts a downward force on the right end, as shown. The magnitude of the force exerted by the student is less than the weight of the ruler. Assume that the pivot point is frictionless. Answer the following questions based on this description. Part A: 1. While the hand is pushing, but before the ruler begins to move, the tangential acceleration of the ruler is 2. While the hand is pushing, but before the ruler begins to move, the centripetal acceleration of the ruler is 3. While the hand is pushing, but before the ruler begins to move, the angular acceleration of the ruler is 4. At the instant the hand has stopped pushing, the tangential acceleration of the ruler is 5. At the instant the hand has stopped pushing, the centripetal acceleration of the ruler is 6. At the instant the hand has stopped pushing, the…

A 48 kg ice skater spins about a vertical axis through her body with her arms horizontally outstretched, making 2.5 turns each second. The distance from one hand to the other is 1.50 mm. Biometric measurements indicate that each hand typically makes up about 1.25 %% of body weight Part A What horizontal force must her wrist exert on her hand? Express your answer in newtons. Part B Express the force in part (a) as a multiple of the weight of her hand. Express your answer numerically as a multiple of w (weight of her hand).
A narrow uniform rod has length 2a. The linear mass density of the rod is p. so the mass m of a length of the rod is pl. Part A A point mass is located a perpendicular distance from the center of the rod. Calculate the magnitude of the force that the rod exerts on the point mass. (Hint: Let the rod be along the y-axis with the center of the rod at the origin, and divide the rod into infinitesimal segments that have length dy and that are located at coordinate y. The mass of the segment is dm = pdy. Write expressions for the I- and y-components of the force on the point mass, and integrate from a toa to find the components of the total force).
