Homework Statement
Well i have a lab practical due for physics and I am having trouble with it. we have to assemble a tri level mobile. that wasn't that hard. the difficult part is doing the math to support my answers. i need to use translational and rotational equilibrium. i looked through my books but i couldn't find anything past a single help problem that doesn't apply to me and a brief explanation
Homework Equations
i don't have any equations because i have no idea how to set it up. can anyone walk me through a practice problem? i would really appreciate it.
The Attempt at a Solution
sorry. i understand that it needs to equal out so the net force equals zero so that it is in balance (equilibrium) I am just not sure how to back it up with my numbers.
