A wood plank (length 4.8 m and mass 9.4 kg) is balanced between two saw horses, as shown in the figure below. One saw horse is positioned directly under one end of the plank, and the other is located a distance di = 3.1 m away. A child (mass 20 kg) walks along the plank, as if it were a balance beam. What is the furthest distance d2 (in meters) from the end of the plank that the child can walk before the plank tips and falls? Hint: When the plank starts to tip, one of the forces becomes zero. d2 d1

00000 The two children sit at opposite ends of a seesaw of negligible mass. The seesaw has a length of 4.0 m and the pivot of the seesaw is at its center. The child on the left end has a mass of 25.0 kg and the child on the right end has a mass of 32.0 kg. Where should an adult of mass 60.0 kg sit to balance the seesaw about its pivot? 20.0 kg 32.0 kg 4.0 m 170 cm left of the pivot 23 cm left of the pivot 87 cm left of the pivot 107 cm left of the pivot 40 cm left of the pivot Next Previous
A cat of mass M and a bowl of tuna fish of mass 2M/5 are at opposite ends of a seesaw of length L = 4 meters. The cat is a distance d from the pivot as indicated on the figure. How far to the left of the pivot must a cat of mass 4M/5 stand to keep the seesaw balance?
Three children are playing on a seesaw. The largest child has a mass of 50 kg and sits on the right side of the seesaw 0.9 m from the fulcrum. The middle child has a mass of 40 kg and sits on the left side of the seesaw 2.5 m from the fulcrum. Where does the smallest child, who has a mass of 25 kg, need to sit in order to balance the seesaw?
Two masses are attached to a uniform meter stick as shown in the figure below. The masses of m1 and m2 are as given and the meter stick weighs 150 g. A force F with unknown magnitude is applied on one end of the stick at an angle of 30° to balance the system. (a) What is the magnitude of F? (Ans: 6.21 N) (b) What are the reaction forces on the support? (Ans: Rx = 5.38 N; Ry = 5.80 N)
Consider a teeter-totter that is made out of pine, shown below. A pineapple sits on one side of the teeter-totter, a distance 1.09 m from the pivot point, while an apple (non-pine) sits on the other side, a distance of 2.63 m from the pivot. If the pineapple has a mass 132 g, what must the mass of the apple be in order to balance the teeter-totter (i.e. to maintain rotational equilibrium)?

You’re carrying a 3.6-m-long, 25 kg pole to a construction site when you decide to stop for a rest. You place one end of the pole on a fence post and hold the other end of the pole 35 cm from its tip. How much force must you exert to keep the pole motionless in a horizontal position?

Ant-Man is walking around on top of a wooden plank that rests atop two thin, vertical steel pillars, which are bolted into the ground. Ant-Man's mass is m₁ = 80.0 kg, but he is small enough to be treated as a point particle. The plank (m₂ = 11.7 kg) has a length of L = 2.44 m, with the left end flush against the edge of the left pillar. The separation distance between the pillars is d 1.50 m. T Suppose that Ant-Man walks far enough out from the right pillar so that the plank is just about to start rotating. What will be the magnitude of the force from each of the pillars on the plank at this time? (Hint: begin your analysis by thinking about the torques acting on the plank, and note that the forces from the two pillars are not the same.) How far out from the right pillar could Ant-Man walk before the plank starts to rotate?

A 7.1 N weight is attached 5.0 cm from the fulcrum of a balance beam. What weight should be placed 1.4 cm away from the fulcrum on the other side of the beam in order to balance the system?
A beam resting on two pivots has a length of L = 6.00 m and mass M = 77.0 kg. The pivot under the left end exerts a normal force n1 on the beam, and the second pivot placed a distance ℓ = 4.00 m from the left end exerts a normal force n2. A woman of mass m = 61.5 kg steps onto the left end of the beam and begins walking to the right as in the figure below. The goal is to find the woman's position when the beam begins to tip. (a) Use the force equation of equilibrium to find the value of n2 when the beam is about to tip. (b) Using the result of part (c) and the torque equilibrium equation, with torques computed around the second pivot point, find the woman's position when the beam is about to tip.x = (c) Check the answer to part (e) by computing torques around the first pivot point.x = (d)Except for possible slight differences due to rounding, is the answer the same for F and E?
