Word Problem #3 Two people want to sit on a see-saw (made of a plank balanced on a fulcrum in the middle) so that it remains horizontal. Persor A has a mass of 50.0 kg and sits on the far left end of the 4.00 m long plank. The 19.0 kg plank has even mass distribution. Person B has a mass of 70.0 kg. a) Where should person B sit to ensure the plank remains horizontal (measured relative to the fulcrum at the middle of the plank)? b) How much force pushes up on the plank at the fulcrum to keep the plank in translational equilibrium vertically?

An 900 N billboard worker stands on a 3 m scaffold supported by vertical ropes at each end. If the scaffold weighs 400 N and the worker stands 1 m from one end, what is the tension in the two ropes that support the scaffold at either end?
Concept Simulation 9.1 illustrates how the forces can vary in problems of this type. A hiker, who weighs 935 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 4500 N, and rests on two concrete supports, one on each end. He stops 1/4 of the way along the bridge. What is the magnitude of the force that a concrete support exerts on the bridge (a) at the near end and (b) at the far end?

A person is pushing a fully loaded 25.40 kg wheelbarrow at constant velocity along a plank that makes an angle a = 32.0° with the horizontal. The load is distributed such that the center of mass of the wheelbarrow is exactly halfway along its length L. What is the magnitude of the total force F, the person must apply so that the wheelbarrow is parallel to that plank? You may neglect the radius of the wheel in your analysis. The F. gravitational acceleration is g = 9.81 m/s². F = N

Consider the woman doing push-ups in the figure. She has a mass of 49.2 kg, and the distance from her feet to her center of mass is 0.96 m, while the distance from her feet to her hands is 1.75m. a. What force in newtons should the woman in the figure exert on the floor with each hand to do a push-up? Assume that she moves up at a constant speed. b. The triceps muscle at the back of her upper arm has an effective lever arm of 1.95 cm, and she exerts force on the floor at a horizontal distance of 15.5 cm from the elbow joint. Calculate the magnitude of the force in newtons for each triceps muscle. c. How much work in joules does she do if her center of mass rises 0.27 m? d. What is her useful power output, in watts, if she does 25 pushups in one minute? For the sake of simplicity, ignore any power used by her muscles lowering her body during each pushup.
