	To analyze the data we can model this system in adams. The simulation to be run will use a step function to define the velocity of the printer head across the paper. This velocity was calculated from the knowledge of how many pages per minute the printer prints and turns out to be 29 inches per second. With this data we can run a simplified simulation of the printers motion.		To analyze the data we can model this system in adams.

This ~~would improve the printer because the printer would be able~~ to ~~pump out printing more pages per minute~~. ~~Also if you had some sort of lubrication mechanism attatched to the support rod~~ this ~~would make the inkjet able to move quicker across the paper~~.	+	The docking station for this printer model seems to be very efficient. This docking process requires no actuator to function, and takes up very little space. Therefore, no improvement is needed for this design.

	The results of the beam analysis showed that the maximum allowable force that the tab could withstand was '''12.8lb'''. The load that the tab will actually be required to withstand is estimated to be .25lb. This gives us a factor of safety of 51.2. This tells us that the tab will never come close to yielding or fracturing. The minimum thickness of the tab was calculated to be .0215in (still assuming the width is three times the thickness). That would be a very small tab, and would actually be harder to manufacture than a larger tab.

 ====The Beam Analysis====
-The vertical tab of the assembly gets contacted by the printer cartridges at the end of each printing session when the cartridges are docked.  This tab must be able to withstand the force of the cartridges without failing.  The tab was modeled as a simple beam of rectangular cross-seciton and bending moment analysis was done to find the maximum withstandable force.

(Some assumptions were: the width of the cross-section is 3 times the thickness, the yield strength is 10,000psi)
