Homework Statement
I am given the equation (m1 – m2)g = (m1 + m2 + I/R2)a and the experiment is to validate this equation.
Homework Equations
The Attempt at a Solution
After following the lab guide, it tells you to plot the weight difference (m1– m2)g against acceleration and determine the slope and y-intercept.
If my graph is correct, than my equation is: y = 34.3x + 56.409
And from here we are asked to solve for I (moment of inertia of the pulley). It also tells us that the equation predicted a zero y-intercept, however a non-zero is expected. why?
I have no idea what to do with the slope or y-intercept in this situation. I was hoping for the radius of the pulley, but that is not given to us, nor is the mass of the pulley.
Please Help.
