You have been hired to design a family-friendly see-saw. Your design will feature a uniform board (mass M= 8 kg, length L = 7 m) that can be moved so that the pivot is a distance d from the center of the board.
You have been hired to design a family-friendly see-saw. Your design will feature a uniform board (mass M= 8 kg, length L = 7 m) that can be moved so that the pivot is a distance d from the center of the board. This will allow riders to achieve static equilibrium even if they are of different mass, as most people are. You have decided that each rider will be positioned so that his/her center of mass will be a...

A uniform beam (mass M = 64.0 kg and length L = 4.90 m) is supported by two triangular supports that are placed a distance D = 2.94 m apart, as shown below. The left-most support is at the very end of the beam. A person (mass m = 22.0 kg) starts walking at constant speed v along the beam, beginning from some point between the two supports. How close can the person get to the right-most end of the...
