Subtitle: Report on the failure of hope as a fuel in powering mechanisms
The assignment for Mechanisms was to build a car that quickly travels 10 feet, powered only by a single mousetrap.
Mike and I set out with what I might call an inspired optimism. We located what we thought was the ideal mechanism for this assignment, despite the fact that all our helpful hints suggested completely different designs. We found a toy car that utilized a pull cord with teeth and a wheel. We designed the car so the mousetrap would pull the cord straight out of the wheel-mechanism. But, we didn’t take into account the fact that this design depends on the counterweight of (usually) a child’s hand pulling the car in the other direction, and then placing the car on the ground. This is not allowed. For the assignment, the car must begin stationary.
Consequently, despite 4 or 5 variations on our design, all of which involved whittling away and reducing the car to the image you see above, it never went further than 8 inches. So, we’ll spend this evening working on PLAN B, which involves a design along the lines of every other successful mousetrap car we’ve seen, all of which have similar attributes.
The 5 hours that resulted in failure yesterday resulted in a great deal of frustration (for me anyway) both during the session and also in the hour or two after. However, the more I thought about, the more I realized the be
nefits of the experience. There were a few things I knew prior to the FAIL process, but I ignored those things. It was as if I was convinced that my own positive thinking about the design idea would propel the car 10 feet, with swift, crisp efficiency. But no amount of awesome thought energy could make the car go. I thought, for example, that perhaps adding some flags to the masts would be all it needed. Of course this was a joke, but it represents my own ability to block logic and math with hopefulness, however unrealistic the idea may be.
And so, again, we’ll head into this evening with a more successful mechanistic approach. You know, hopefully.
