Office Hours Correction: Max power of a motor (number 1g) is given by: 
TBD Values:L1 = 15cm L2 = 5cm
M_disk = 230g I_disk= 5.26e-4 Kgm^2 Disk 2b is the same as Disk 1
p1 = 10t XL pulley p2 = 42t XL pulley
Part 1 Clarifications:c.i) method 2 alludes to but does not specifically give the formula. Where I and \omega are the no load current and speed.
f.i) Use a time constant of .005s. The suggested constant will bias the data. The "Turn in" section also asks you to use a curve fit function in matlab, which could be suggesting the fit() function?
Part 2 Clarifications:Assumptions: - pulleys and shafts are massless
- Pulleys an disk in 2b are evenly spaced, see below for clarified diagram
- the angle of the timing belt is neglible
- the timing belts have no pre-tension
- there is no viscous friction
2a) Instructions:- Draw a FBD of the single shaft setup.
- List equations of motion
- Model the system in matlab with a disk and without (only motor inertia)
- for both, plot: displacement (radians) and
filtered velocity (rad/s) vs time (on the same plot). Filtered????? This is a numerical simulation, there is nothing to filter! - for both, plot: motor torque (Nm) and Power (W) vs time (on the same plot).
2b) Instructions: - You do not need a FBD. You can derive the equivalent inertia and friction using energy methods.
- Model the system in matlab with a disk and without (only motor inertia)
- for both, plot: displacement (radians) and velocity (rad/s) vs time (on the same plot).
- for both, plot: motor torque (Nm) and Power (W) vs time
