A seesaw is a flat board that is balanced on a fulcrum (point of balance). When the weight at either end is equal, the seesaw is balanced and both ends are at the same height. When weight is added to either side, the balance will tilt in that direction. To prevent the balance from tipping, the location of the fulcrum must be moved to accommodate the difference in weights placed on each end. A playground equipment company wants to produce a seesaw that will be perfectly balanced when an adult and a child are on either end. The company estimates that an adult, on average, weighs four times as much as a child. The length of the seesaw is 10 feet.

You have been hired to design a family-friendly see-saw. Your design will feature a uniform board (mass M = 5 kg, length L = 2.4 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 = 11 cm from the end of the board when seated as shown.You have selected a child of mass m1 = 21 kg (shown on the right), and an adult of mass m2 = 65 kg (shown on the left) to test out your prototype. a) Determine the distance d in meters. b) Determine the magnitude of the force exerted on the pivot point by the see-saw while in use in newtons.
A rigid beam of length 1.8 m is in equilibrium, with one end attached to a wall by a hinge, and the other end held in place by a thin, massless wire as shown in the figure on Zoom. The wire will break if tension exceeds 1300 N. What is the maximum mass of the beam that can still be supported by the wire?
A L=4 m long ladder with mass m=10 kg is leaning against a frictionless wall and on a floor with a friction coefficient of 0.5. The ladder's center of mass is in the middle of the ladder. Calculate the largest opening angle between the ladder and the frictionless wall for which a person of mass 75 kg can climb all the way up the ladder without it slipping.
The diagram above shows a 3.00 m long uniform beam. The left end of the beam is attached to a wall by a frictionless pivot. The beam is supported by a string that keeps the beam horizontal. The string makes an angle of 35.0° relative to vertical. The beam has a mass of 7.00 kg. A 2.00 kg mass is located at the end of the beam. A 6.00 kg mass is located 1.00 m from the 2.00 kg mass, as shown in the diagram. a. What is the tension in the string? b. What is the y-component of force applied to the beam by the pivot?
Two children are trying to balance on a seesaw, which includes a fulcrum and a board that is 10m long. Boy A has a mass of 50kg, and boy B has a mass of 35kg. How far from the pivot point should boy B be to maintain stable equilibrium?
A 5.2-m ladder rests against a wall as shown. The ladder has a mass of 27.6 kg. A 56.3-kg person stands on the ladder at a distance of 3.6 m from the bottom of the ladder. The foot of the ladder is 1.9 m from the bottom of the wall. Assume there is no friction between the ladder and the wall so that the force of the wall on the ladder is acting only in the horizontal direction. However, there is a friction force between the ladder and the ground. 1.) What is the force, in N, exerted by the wall on the ladder?
Review Conceptual Example 7 before starting this problem. A uniform plank of length 5.0 m and weight 225 N rests horizontally on two supports, with 1.1 m of the plank hanging over the right support (see the drawing). To what distance x can a person who weighs 375 N walk on the overhanging part of the plank before it just begins to tip? X = i 41.1 m²
A horizontal 8 kg plank is 3.0 m in length and has its center of mass at the geometrical center. A 2 kg mass is placed 1.0 m from one end and the plank is supported from the ends. Calculate the forces of support. 1.0 m 2 kg 3.0 m
Bob and Anna sit on opposite ends of a uniform see-saw which is 12.0 m in length. The see-saw is balanced by a fulcrum which is located 4.00 m from Bob. Bob has a mass of 85.0 kg, and the see-saw itself has a mass of 100 kg. Anna’s mass is unknown. NOTE THAT THE FULCRUM IS NOT PLACED AT THE CENTER OF MASS OF THE SEE- SAW!!! a) What is the net torque on the see-saw? Explain clearly and briefly how you know. b) Draw a properly labeled extended force diagram of the see-saw c) Solve for Anna’s mass. Show your work clearly!
Three children are trying to balance on a seesaw. The seesaw is 3.7 m long and pivots about a rock at its center. Louie and Laura are already sitting on opposite ends. If Martha weighs 29 kg, where should she sit so as to balance the seesaw?
