Question

how do I do this?

idku · Answer

A meter stick with mass of $51~{\rm g}$ is balanced at its midpoint ($50~{\rm cm}$, zero point is a left end of stick). Then $m_1$ that weighs $230~{\rm g}$ is hung with a light string from the point $l_1=68.0~{\rm cm}$, and $m_2$ that weighs $115~{\rm g}$ is hung from the point $l_2=14.0~{\rm c m}$ point. Calculate the clockwise and counterclockwise torques acting on the board due to the four forces shown about the following axes: IMAGE: https://www.flipitphysics.com/Content/smartPhysics/Media/UserData/eaf24a0d-5aa7-d4d7-82e3-4f3a9061982b/Freed_CollPhysics1e_Figure8-54.jpg

What I have to determine here is,

The clockwise torque if the axis is the 0-cm point.
The counterclockwise torque if the axis is the 0-cm point.
The clockwise torque if the axis is the 50-cm point.

and a bunch of other stuff....

my teacher hasn't gone through this stuff, so hopefully I can figure out how to do this here:) Anyone knows?
