THANKS, I ONLY NEED HELP #2 NOW, PLEASE
10/31/12 @ 9:10 pm bump
1)If the fulcrum of a 0.1 kg meter stick was placed at the 40 cm mark and a 200 g mass at the 0 cm mark, would it be possible to balance the meter stick with a 200 g mass on the long side of the meter stick? What would the position of the mass have to be to balance the meter stick?
2) What is the torque acting on the pulley system below
LA1=LA2
Torque net= radius x force
FROM DIAGRAM
#2, this is my first time working on this type of problem. how should I combine the other "counterclockwise" 2 pulleys? value correct? 10N x radius #2 of 1m= 10Nm
and the other T1=15N x radius#1 of 2m= 30Nm??
How do i combine these 2 forces? Are they negative?I understand 60Nm is correct from the clockwise but not the other. Please help!
Please help -- Greatly Needed
