Here is our Introduction to Engineering Final Project created by Michael Donohue, Daniel Lechuga, Jonathan Zambrano, Kory Seaton, Cameron Sunshine-Longway, and Leonardo Arenas.




We release the fork allowing the cup to roll down the inclined surface.
The cup strikes a set of dominoes which split off into two processes.
Process one of the dominoes knocked over a weight made of a baseball and nut off the table.
When the weight would fall it was looped through two different points of direction change with a string and would tension said string.
The string being tensioned was attached to our envelope with a paperclip, the weight tensioning the string pulled the envelope
When the envelope was pulled it was rolled through a dampened paint roller and put into place for sealing and stamping.
Process two of the dominoes knocked a water bottle attached to a weight by a string off of the table.
The release of the weight from the water bottle let a string attached to a pendulum loose.
The pendulum is released and stikes a jenga block which topples into the marble, setting it in motion.
The marble moves through a tube and drops down onto a balance beam with a cup on each side.
The marble’s weight pulls its cup down and releases a ball on the other side of the cup “seesaw.”
The released ball rolls down an incline and strikes a block.
The block topples a larger sized block to gain energy and the largest one knocks over a toppling weight.
The toppling weight is made of a box of golfballs which pulls on two items. The string first tensions through a pulley, making it’s downward falling force actually pull upward, we attached that string to the handle side of a hammer to topple it off the table adjacent to our envelope.
Also attached to the head of the hammer was another string which would pull a block of wood attached by a hinge over the flap of the envelope to seal it when the hammer fell off the table and was suspending/tensioning the string to pull the wood block over.
The string attached to the falling golfball box was also attached to a stopper on a metal track, when the box fell it allowed a new ball to roll.
The heavy ball then rolls down a track and falls into a bucket attached to a rolling pulley.
When the ball hits the bottom of the bucket it breaks a fishook that is suspending the pulley, which was necessary because of  we couldn’t have any counter weight on the pulley so we could utilize the falling power of the bucket and ball.
When the hook did break the bucket was attached to a wooden arm on a rotating hinge by a string that first looped through a frictionless axis point that was higher than the bucket, then one that was lower than the arm so we could pull one side of the lever down with the bucket even though the bucket is higher in elevation.
The bucket fell and tenionsed the string attached to arm and punched the stamp on the opposite side of the lever arm upward onto our envelope
