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.

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?when one boy is sitting 1.2 m from the center of a see-saw, another boy must sit on the other side 1.5 m from the center to maintain an even balance. However, when the first boy carries an additional weight of 14 kg and sit 1.8 m from the center, the second boy must move to 3 m from the center to balance. Neglecting the weight of the see-saw, find the weight of the heavier boy.
- A meter stick balances horizontally on a knife-edge at the 50.0 cm mark. With two 5.85 g coins stacked over the 14.5 cm mark, the stick is found to balance at the 20.6 cm mark. What is the mass of the meter stick?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.
