Three people are balanced on a uniform seesaw -- Torque
Three people are balanced on a uniform seesaw which has a weight of 150 N as shown in the figure.
Find the mass of person B and the normal force acting on the fulcrum.
Tcw=Tccw
There was a problem that involved mass and a fulcrum in my notes, it doesn't have a force or weight of the fulcrum, but I tried to set it up like the example to find the mass of person B
(mC)(5.4)=(mA)(0)+(mB)(1.2). I then solved for mass B. I am not sure if I have to also put the weight of the fulcrum in there or not.
