		+	From this graph, the maximum gear force was found to be about 0.3 N. This value is much less than the force at which the plastic gear would deform (1e5 N), verifying that the design is a safe for operation. This also verifies that this design meets the user requirement that the gear set up would not fail due to deformation.

	Analysis will have to be performed on the operating conditions of the printer. The coefficient of the rubber wheels on the paper will have to be found along with all of the geometric parameters of the system. For example, the radii of the wheels, their thickness, and their density will all have to be found in order perform the analysis in ADAMS. All geometric parameters, moments of inertia and yield strengths will be have to be found to perform the analysis. Finally, the force that is necessary to slide the paper (adding to the resistance of the motion) will also need to be found. This will be found by using the coefficient of friction mentioned earlier.		Analysis will have to be performed on the operating conditions of the printer.

	From this analysis, it is clear that the smaller plastic gear is more robust than is necessary. The amount of force that is applied to the gear is no where near a force that would cause any significant deformation. However, it is important to remember that this analysis is only of one aspect of the forces that are applied to this gear. It is possible that cyclic loading forces the gear to be as large as it is. Also, it is possible that this gear size is either easily manufactured or readily available. Therefore, it would be less expensive to use this gear rather than manufacture a gear that is of a different size.
