A meter stick has a mass of 0.12 kg and balances at its center. When a small chain is suspended from one end, the balance point moves 12.0 cm toward the end with the chain. Determine the mass of the chain.
Homework Answers
considering equilibrium of moment
mg * d = M g ( 1/2 - d)
0.12* 0.12 = M ( 0.5 - 0.12)
M = 0.0379 kg
M = 37.9 gram

A uniform meter stick (a ruler 100 cm long) is supported by a fulcrum at its 20 cm mark balances when a 200 g mass is suspended at the 0 cm end. Assume that the center of mass of the meter stick is exactly at its middle, the 50 cm mark. Determine the mass of the meter stick, in grams. Please show your work.

A uniform meter stick of mass $M$ has a half-filled can of fruit juice of mass $m$ attached to one end. The meter stick and the can balance at a point 19.6 cm from the end of the stick where the can is attached. When the balanced stick-can system is suspended from a scale, the reading on the scale is 2.59 N. A.)Calculate the mass of the meter stick. B.)Calculate the mass of the can of juice.

4) A 1 meter-long, funny-shaped meter stick has an unknown mass but a center of gravity located at 0.75 m from the left end. When a metal wedge is placed at the middle of the bar and a .50-kg mass is hung from the left end, the bar balances perfectly on the metal wedge. a) Determine the mass of the funny-shaped meter stick (10 pts). b) Calculate the amount of upward force provided by the metal wedge (10 pts).

Torques and Center of Mass. The
Experiment:
In this experiment, you balance a meter stick, to balance the
meter stick, attach masses at positions until the system is in
equilibrium.
The meter stick acts as if all its mass was concentrated at its
center of mass. With the fulcrum at the center of mass, r (the
distance from the axis of rotation to the place where the force is
applied) is 0, so there’s no torque due to the meter...
