A) Calculate about point C, the center of mass (CM)
B)Calculate about point P at one end.
Homework Equations
[itex]\tau=F*\theta[/itex]
The Attempt at a Solution
In this case I have the answers for the values with the same figure, so I know the summation of forces along this pole must be equal to 8.5 N. From there I multiply the length of my bar to get 38 Nm, which is correct. However, I don't know how to get this from the figure. From there, I have no idea how to get the torque around point p.
