Homework Statement
The question is from a lab. The lab used an Atwood Machine with two masses suspended string looped over a pulley. The time for one mass to reach the ground was measured and acceleration of the mass was calculated. The results were plotted on a graph of weight difference (Y) vs acceleration (x).
The question is from the linear fit, slope value, calculate the moment of inertia of the pulley.
Linear Fit equation y=mx+b
m(slope): 6.762 g/m/s^2
Homework Equations
I= 1/2mr^2
The Attempt at a Solution
Many attempts at trying to determine the moment of interia from the slope, however I get lost because the radius of the pulley was not measured in the lab. The assumption is made that pulley it self in frictionless.
Thanks in advance
