Report: Analyze a Dynamics System with a Pulley
Materials: Experimental Set-up as seen in Figure 4.1 and Figure 4.5.
Tasks:
1) Theoretical Analysis of System
a. Use Newton’s second law to prepare an equation that would allow us to solve for tension force and
acceleration. No numbers should be involved.
b. A system FBD and FBDs for each individual object should be the starting point.
2) Experimental Analysis of System
a. Use Capstone graphical analysis software and your experimental set-up to determine the tension force
in the string and the acceleration of the system.
b. Prepare and analyze: Force vs time and velocity vs time graphs for the motion.
c. Complete at least three trials and use the average of your trials for all analysis.
3) Comparison of theoretical and experimental results
a. Use your equations to determine the theoretical values of tension force and acceleration.
b. Compare your theoretical and actual values by performing a percent error calculation. Identify sources
of error in the experimental set-up.
c. The mass of the pulley and the friction in the bearings of the pulley and cart are small. Is your data
consistent with the pulley or cart having a small but nonzero effect on the motion? Explain using your
data.
4) Real Life Application
a. Provide a theoretical analysis of this dumb waiter system. No numbers necessary.
