You have been hired to design a family-friendly see-saw. Your design will feature a uniform board (mass M = 10 kg, length L = 3.4 m) that can be moved so that the pivot is a distance d from the center of the board. This will allow riders to achieve static equilibrium even if they are of different mass, as most people are. You have decided that each rider will be positioned so that his/her center of mass will be a distance xoffset = 14 cm from the end of the board when seated as shown.You have selected a child of mass m1 = 29 kg (shown on the right), and an adult of mass m2 = 71 kg (shown on the left) to test out your prototype. Determine the distance d in meters. Determine the magnitude of the force exerted on the pivot point by the see-saw while in use in newtons.
A board of mass 3.0Kg serves as a seesaw for two children. Child A has a mass of 40Kg and sits 2.5m from the pivot point. At what distance x should a child B of mass 25Kg sit from the pivot point so as to balance the seesaw? What is the normal force at the pivot point? Assume the board is uniform and centered over the pivot.
To get up on the roof, a person (mass 70.0 kg) places a 6.00-m aluminum ladder (mass 10.0 kg) against the house on a concrete pad with the base of the ladder 2.00 m from the house. The ladder rests against a plastic rain gutter, which we can assume to be frictionless. The center of mass of the ladder is 2.00 m from the bottom. The person is standing 3.00 m from the bottom. Find the normal reaction and friction forces on the ladder at its base.
Chapter 12, Problem 037 GO In the figure, a uniform plank, with a length L of 6.83 m and a weight of 386 N, rests on the ground and against a frictionless roller at the top of a wall of height h = 2.78 m. The plank remains in equilibrium for any value of e = 70.0° or more, but slips if e < 70.0°. Find the coefficient of static friction between the plank and the ground.

A ladder leans against a wall 5 meters above the ground so a homeowner can clear his gutters of leaves from last fall. The bottom of the ladder just begins to slip when it is 7.1 meters from the wall. What is the coefficient of static friction between the bottom of the ladder and the ground?
An object can rotate but not exhibit no angular acceleration and no linear or translational acceleration. Such an object is in both translational and rotational equilibrium. What are the conditions for the object to be in static equilibrium? A vaulter holds a 29.4 -N pole in equilibrium by exerting an upward force U with her leading hand and a downward force D with her trailing hand as shown. Point C is the center of gravity of the pole where the 29.4 N acts. Determine: The magnitude of U The magnitude of D
A uniform ladder 5.0 m long rests against a frictionless, vertical wall with its lower end 3.0 m from the wall. The ladder weighs 140 N. A man weighing 620 N climbs slowly up the ladder. Start by drawing a free-body diagram of the ladder. What is the actual frictional force when the man has climbed 1.0 m along the ladder? [Hint: Draw a free body diagram to determine what forces are at play. Then use the torque formula (T = Fxrx sine) to find the net torque.]
A 2.00-m-long, 500 kg steel uniform beam extends horizontally from the point where it has been bolted to the framework of a new building under construction. A 70 kg construction worker stands at the far end of the beam. What is the magnitude of the torque about the bolt due to the worker and the weight of the beam?
A hungry bear weighing 700 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (Fig. P8.22). The beam is uniform, weighs 200 N, and is 6.00 m long, and it is supported by a wire at an angle of 0 = 60.0°. The basket weighs 80.0 N. (a) Draw a force diagram for the beam. (b) When the bear is at x = 1.00 m, find the tension in the wire supporting the beam and the components of the force exerted by the wall on the left end of the beam. (c) If the wire can withstand a maximum tension of 900 N, what is the maximum distance the bear can walk before the wire breaks?
To a light beam (of negligible mass), two antiparallel forces are applied, as shown in the figure. These forces cause a net torque equal to 8.9 Nm (and with the same direction as that caused by F2) at the left end of the beam. If F1 = 9.8 N and F2 = 5.7 N, determine the distance "l" that separates them.
When a gymnast weighing 740 N executes the iron cross as in figure (a), the primary muscles involved in supporting this position are the latissimus dorsi ("lats") and the pectoralis major ("pecs"). The rings exert an upward force on the arms and support the weight of the gymnast. The force exerted by the shoulder joint on the arm is labeled F while the two muscles exert a total force F on the arm. Determine the magnitude of the force F Note that one ring supports half the weight of the gymnast, which is w 370 N as indicated in figure (b). Assume that the force F acts at an angle of 45° below the horizontal at a distance of 4.0 cm from the shoulder joint. In your estimate, take the distance from the shoulder joint to the hand to be L = 75 cm and ignore the weight of the arm. m kN Shoulder joint 4.0 cm- 45.00 Ed Bock/CORBIS
