Chapter 9, Problem 5PE
Repeat the seesaw problem in Example 9.1 with the center of mass of the seesaw 0.160 m to the left of the pivot (on the side of the lighter child) and assuming a mass of 12.0 kg for the seesaw. The other data given in the example remain unchanged. Explicitly show how you follow the steps in the Problem-Solving Strategy for static equilibrium.

- In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?arrow_forwardTwo children of mass 21 kg and 26 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw. If the children are separated by a distance of 2 m, at what distance from the pivot point is the small child sitting in order to maintain the balance? marrow_forwardModeled after problem 5 in the Problems_Torque_Statics: A 13.98-m-high and 12.18-m-long wall under construction and its bracing are shown in the figure. The wall is in stable equilibrium without the bracing but can pivot at its base. Calculate the force exerted by each of the 10 braces if a strong wind exerts a horizontal force of 586.31 N on each square meter of the wall. Assume that the net force from the wind acts at a height halfway up the wall and that all braces exert equal forces parallel to their lengths. Neglect the thickness of the wall. The angle between the braces and the wall is as shown in the figure as 35 degrees.arrow_forward

- Answer using 3 Significant FIgures.arrow_forwardBart ( whose mass is 31.1 kg) and Milhouse (whose mass is 20.4 kg) sit balanced on a teeter -totter that has its pivot point at its exact center . If the two boys are separated by a distance of 2.52 m, at what distance (in m) from the pivot point must Milhouse be sitting at in order to maintain the balance? Explain how you solved the problem involving children balancing on a teeter-totter. Be sure to state what your known and unknown quantities are, what concepts were applied, and what equations were used!arrow_forwardA seesaw consisting of a 1-kg board and length of 4 m balances Tony and Steve, as shown below. The support is under the center of gravity of the board, and Tony, with a mass of 30 kg, is seated 2 m from the support. a) Determine the distance from the support at which Steve (m = 35 kg) must sit to balance the system at rest. b) Find the magnitude of the upward force exerted by the support on the board.

- 9.4arrow_forwardA uniform beam of weight 58 N and length 6.0 m is mounted by a small hinge on a wall at it left end. The beam is held in a horizontal position by a vertical rope at the location as shown. What is the magnitude of the tension force in the rope, in Newtons? Your answer needs to have 2 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement.arrow_forwardIn exercise physiology it is sometimes important to determine the location of a person's center of gravity with respect to the plantar area. This can be done with the arrangement shown in the figure. A lightweight plank is supported by two scales that indicate Fg1 = 380.0 N and Fg2 = 320.0 N. The scales are separated by a distance of 2.00 m. At what distance from the woman's feet is her center of gravity? If a) the weight of the plank is neglected. b) if the plank has a weight of 55.0 N.arrow_forward
