A wood plank (length 4.4 m and mass 13.0 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 d1 = 3.4 m away. A child (mass 25 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.

- A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 3.74 g coins stacked over the 26.6 cm mark, the stick is found to balance at the 45.8 cm mark. What is the mass of the meter stick?A meter stick balances horizontally on a knife-edge at the 50.0 cm mark.

What is the mass of the meter stick?Jackey is standing terrified and trembling at the end of a diving board, which is high above the water. If Jackey has a mass of 114 kg and is standing 2.9 m from the board's pivot point, what torque (in N-m) is Jackey exerting on the board?
- The meterstick shown is 100 cm long. It is free to pivot around its center of gravity (CG), which is at the 50 cm mark. There is a 24.0 N block hanging from the 80 cm mark. Decide where each of the other blocks should be placed, one at a time, to balance out the 24.0 N block. At what mark on the meter stick would you place a 19.0 N block to balance the 24.0 N block? mark: At what mark on the meter stick would you place a 44.0 N block to balance the 24.0 N block? mark:The angular momentum of a spinning wheel is 218 kg·m2/s. After application of a constant braking torque for 2.30 s, it slows and has a new angular momentum of 115 kg·m2/s. What is the torque applied? If the applied torque is in the direction of the rotation of the wheel, enter a positive value and if the applied torque is opposite to the rotation of the wheel, enter a negative value.A gymnast with mass 55.0 kg stands on the end of a uniform balance beam as shown in the figure below. The beam is 5.00 m long and has a mass of 250 kg (excluding the mass of the two supports). Each support is 0.700 m from its end of the beam. In unit-vector notation, what are the forces on the beam due to support 1 and support 2? L. (a) F1 = N (b) F2 = 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 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?
- Three children are trying to balance on a seesaw, which consists of a fulcrum rock, acting as a pivot at the center, and a very light board 3.4 m long (Figure 1). Two playmates are already on either end. Boy A has a mass of 45 kg, and boy B a mass of 35 kg. ▼ Part A Where should girl C, whose mass is 25 kg, place herself so as to balance the seesaw?

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?A meter stick balances horizontally on a knife-edge at the 50.0 cm mark.
