Paper Airplane Building Machine

 

This project is a group project that involves three parts:

 

1-  Paper Loading, Power Source, and Machine Frame.

2-  Paper Forming.

3-  paper launching.

​

​

Analysis of the the first portion of the project:

 

For the thickness of the material used in designing the frame has to be considered. To calculate the proper thickness first the forces exerted on the frame had to be calculated by using shear and moment diagram. Also, assume that the frame had a contributed load of 8 lb/in. The formula of bending stress then is used to find the section modules. Finally, the section modules equation is used to find the thickness.

 

S = M/S

 

S = h(t^2)/6

​

The thickness is found to be (0.106 in)

​

For the loading device two choices are available rollers and belts. Rollers are going to be use in this project because they are cheap, easy to handle, flexible and they don’t take much space. 

 

The equations of rotational motion were used to calculate the time for the loading process: 

​

ωf^2 = ωo^2 + 2 α θ

ω = ωo + α t

​

The calculated time found to be 56 seconds.
