- An object is in equilibrium. There are three forces & three torques acting on it. Complete the table below. FB (N) 700 right Magnitude Direction (N) 900 left FC (N) -Select-v TB (N-m) (N-m) 100 200 clockwise clockwise -Select- TC (N-m)A child with a mass of 11 kg sits at a distance of 1 m from the pivot point of a seesaw. Where should a 15 kg child sit to balance the seesaw?m (from the pivot point)A tightrope walker is walking between two buildings holding a pole with length ?=15.5 m, and mass ??=19.5 kg. The daredevil grips the pole with each hand a distance ?=0.575 m from the center of the pole. A bird of mass ??=525 g lands on the very end of the left‑hand side of the pole. Assuming the daredevil applies upward forces with the left and right hands in a direction perpendicular to the pole, what magnitude of force ?left and ?right must the left and right hand exert to counteract the torque of the bird?
- Two kids are on a uniform seesaw supported at its center. The kid is on the right side of the seesaw has a mass m kg and is at a distance 1.59 from the center of the seesaw. The kid is on the left side of the seesaw has a mass 30.8 kg and is at a distance 1.49 from the center of the seesaw. The seesaw is in static equilibrium. What is the mass m in kg? Give your answer to three significant figures.A 50 N weight is located 20 cm from the fulcrum of a balance beam. At what distance from the fulcrum should a 20 N weight be placed to balance the system?When opening a door, you push on it perpendicularly with a force of 52.5 N at a distance of 0.825m from the hinges. a) What torque are you exerting relative to the hinges?
- A tower crane (Figure 1) must always be carefully balanced so that there is no net torque tending to tip it. A particular crane at a building site is about to lift a m = 2700-kg air-conditioning unit. The crane's dimensions are shown in (Figure 2). The crane's counterweight has a mass of M = 10000 kg . Ignore the mass of the beam. Where must the crane's counterweight be placed when the load is lifted from the ground? (The counterweight is usually moved automatically via sensors and motors to precisely compensate for the load.)Express your answer to two significant figures and include the appropriate units. Determine the maximum load that can be lifted with this counterweight when it is placed at its full extent.Express your answer to two significant figures and include the appropriate units.13. Freddy who weights 20kg, sits on one side of the seesaw which is 3.5m away from the center. His father sits on the other side and balances the seesaw. If his Father weights 70kg, how far away from the center is he sitting? 14.
