My teacher never really taught how to draw one but I asked a friend and they showed me how. For B since both of the forces and going downward I just subtracted it then multiplied to find the force.
For A, I had multiplied 65 and 9.8 since that’s the force of gravity.
For B, I again multiplied 65 and 2.5 (that’s what the scale says it reads.
*I believe you multiply them for c and d, but I’m not positive for it.
C- I think you multiply then subtract
D- I think you multiply and I’m not sure...
