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 29.0 cm toward the end with the chain. Determine the mass of the chain.

Expert Solution

Initially the balancing point is at center of the meterstick.i.e., at 50 cm point
mass of the meter stick m = 0.12 kg
weight of the stick W = m g
                                = 0.12*9.8 = 1.176 N
After suspended neckalce balancing point is moves 29 cmtoward that end.
So, moment of force of stick = moment of force ofneckalce
                              W* 29 = W ' * ( 50 -29 )
                         1.176* 29 = 21 * W '
from this weight of the necklace   W '= 1.624 N
So, mass of the necklace m ' = W ' / g
                                            = 0.1657 kg
                                            = 165.7 g

1) A meter stick is placed in a support stand and balanced at its center of gravity. A 50 gram mass is placed at the 25.00 cm mark.

1) A meter stick is placed in a support stand and balanced at its center of gravity. A 50 gram mass is placed at the 25.00 cm mark. An unknown mass is placed on the other side of the meter stick and moved until the entire system is balanced. If the unknown mass is placed at the 75.00 cm mark, then what is the value of the unknown mass? Ignore the mass of the knife-edge clamps and assume that...

A uniform disk with mass 8.5 kg and radius 8 m is pivoted at its center about a horizontal, frictionless axle that is stationary. The disk is initially at rest, and then a constant force 31.5N is applied to the rim of the disk. The force direction makes an angle of 35 degrees with the tangent to the rim. What is the magnitude v of the tangential velocity of a point on the rim of the disk after the disk...
