Homework Statement
The four highlighted questions are the ones that I am having trouble with. Unfortunately, the second question in both sections builds upon the first so its hard to go any further but I would know how to solve the second part if I could create the equation. In the first procedure it asks to create an equation for the total torque. I understand it must be equal to zero but not the values that must go on the right side of it. I do know though how to solve for the values (which should be R and W), after the equation is created.
The question was stated as "Use the forces of torque acting on the ruler about point B (when center of gravity is equal 4.) Then create an equation using Στ = 0 this should be labeled equation 3.
The second question requests that the equation originally created (W*x=.1*(m*g)) be converted into y=mx.
The question was stated as, "write the equation in y=mx."
I attached 3 .jpg to show the work I have already done, as well as to provide a background of the nature of the question.

The Attempt at a Solution
In the first procedure it asks to create an equation for the total torque. I understand it must be equal to zero but not the values that must go on the right side of it. I do know though how to solve for the values (which should be R and W), after the equation is created.
The second set of directions in procedure two ask to make the equation I had made in part one (W*x=.1*(m*g)) into y=mx. In the equation previously sated, I thought the x was the dependent variable and m was the independent variable, leaving W to be the part of the slope. I rearranged the equation several times and got the value of .42 as the answer which doesn't seem right according to the graph that corresponds to it. If I can get help on the equation portion the second two questions will be much easier to solve. Thank you for your time.
