Homework Answers
The meter stick is in static equilibrium so the net force on it is zero.
T1 + T2 = Mg ==> 627+455 = M x 9.81 ==> M=110.29 kg
(b) Equating the torque
about point A
Ta=Mgx-T2 x l =0
l=38-12=26 cm = 0.26 m
110.29 x 9.81 x ? = 455 x 0.26 ==> ? = 0.109 m = 10.9 cm
so the position of mass = 10.9 + 12 = 22.9 cm
Hope you will find the answers useful. Please rate. Cheers.

55) A 0.15-N meter stick is suspended from a spring scale at its 25-cm mark. When an object of unknown mass is hung from the meter stick on the 10-cm mark, the meter stick is in equilibrium. Draw an extended-body force diagram for the meter stick and (a) determine the mass of the object and (b) the reading on the spring scale.

the fulcrum is positioned at the 50cm mark on the meter stick. A 50g mass is hung from 67 m mark on the stick. Also a 200g mass is suspended from the 89 cm mark. A. Calculate the total clockwise torque due to these masses B. assuming that the total counterclockwise torque is equal to the answer in (A) above, calculate the position on the meter stick where 315g mass must be suspended in order to balance the stick.

A meter stick is mounted to a vertical post such that it is free to rotate in the vertical plane. The rotation axis and center of mass of the meter stick are at the same location. Two masses are attached to the meter stick as shown. M2 is 2.5 kg and is attached to the right end of the stick, i.e 50 cm from the rotation axis. M1 is attached to the left side of the meter stick a distance...

A 0.104 kg meter stick is supported at its 40 cm mark by a string attached to the ceiling. A 0.644 kg object hangs vertically from the 7.09 cm mark. A second mass is attached at another mark to keep it horizontal and in rotational and translational equilibrium. If the tension in the string attached to the ceiling is 17.4 N, find the value of the second mass. The acceleration due to gravity is 9.8 m/s 2 . Answer in...
