Homework Statement


A horizontal meter stick has a mass of 217 g. Three weights ride on the meter stick: 265 g at 40.7 cm, 191 g at 75.9 cm, and 195 g at 99.3 cm. At what location on the meter stick would the system be in balance if it were suspended there?

Homework Equations


ƩF=0
Ʃτ=0
Center of mass (x-dimension) = (M1X1 +M2X2...)/(M1+M2...)

The Attempt at a Solution


I know that in order for the system to balance the torque on the system as well as the net force must both equal zero. I have just begun this section and I am not really sure how to approach this problem. Thank you for your time.
