A meter stick is balanced on a fulcrum located at 0.50 m. A spring scale is hung from the meter stick at 0.90 m and a counterbalance is hung at 0.10 m so that the meter stick is level. If a mass of 125 grams is hung at the 0.35 m position on the meter stick, what force do you have pull on the spring scale in order to make the meter stick level? ANSWER: 0.46N. Please explain/show work.

Two movers are carrying a 4.0 m long sofa with a uniform distribution of mass along its entire length. One of them is standing all the way at one end, and provides a 350 N upward vertical force F1. The other is standing halfway between the midpoint and the other end. Fg is in the center! a. What is the force F2 needed at this location to prevent the sofa from rotating? b. What is the mass of the sofa?

An 88 kg person stands on a uniform 5.6 kg ladder that is 4.0 m long, as shown in the figure(Figure 1). The floor is rough; hence, it exerts both a normal force, f1, and a frictional force, f2, on the ladder. The wall, on the other hand, is frictionless; it exerts only a normal force, f3. Using the dimensions given in the figure, find the magnitudes of f1, f2, and f3.

A uniform, 254-N rod that is 1.89 m long carries a 225-N weight at its right end and an unknown weight W toward the left end (see the figure (Figure 1)). When W is placed 42.0 cm from the left end of the rod, the system just balances horizontally when the fulcrum is located 69.2 cm from the right end. A) Find W. B) If W is now moved 29.3 cm to the right, how far must the fulcrum be...
