The diagram above represents an object held in static equilibrium by three cables. If F1 = 460 Newtons and F2 = 580 Newtons, what should the magnitude of F3 be? number unit F1 is at a height 2.7 meters above the center of mass, while F2 goes directly through the center of mass. How far up should F3 be from the middle of the object in order to balance the torque?

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 uniform 10.0 m ladder of weight WL=375 N leans against a frictionless wall. There is a force of static friction between the floor and the bottom of the ladder. A person weighing Wp stands 7.4 m between the bottom of the ladder. Draw a free body diagram for the ladder. Draw a torque diagram for the ladder.

The uniform seesaw shown below is balanced on a fulcrum located d1 = 3.5m from the left end. The bigger boy on the left end has a mass m1 =75 kg. The smaller boy on the right end has a mass of m2 = 55 kg and is a distance d2 = 4.5 m from the fulcrum. The mass of the board is mb. Draw all forces acting on the seesaw board showing their directions and locations. Where would you draw the weight of the board? Identify and show the direction of rotations caused by the torques provided by all forces about the fulcrum. If the seesaw is in static equilibrium, write down the two conditions of static equilibrium symbolically using the forces and distances in the figure. Solve for the mass of the board. Calculate the force of fulcrum on the board.
