Finding a position vector of a pivot on a lever from its torque
Hi guys, I have a problem here which I'm really stumped on.
I have a rigid rod of 3.1m length, with two equal masses at either end. The pivot is placed so that the total torque is 25k N.m about the pivot, and I need to find it's location.
I've drawn a diagram, a basis, calculated that the Torque, 25k, will be given by A1F1A2F2 where the forces are the weights of the masses and A1 and A2 are the position vectors in the i direction.
Any advice on how to approach it? I tried to define the A1 and A2 as x and 3.1x but this isnt working as far as I can tell.
Any advice would be appreciated, cheers!
