Keenerpult by Isaac Sinton-Remes
On the way back from the Gatineau, Stephen tasked me with the project of making the Keenerpult a catapult that could launch the average keener halfway to Corner wave. After careful consideration despite Keenerpult sounding much better than Keenerchet, a trebuchet is a much more effective design for launching keeners (and other object I guess). This blog is the initial calculator to determine the viability of such a device and weight of the counterweight needed. Using Google Earth I measured the distance from Keenerville to Corner wave at about 1400 feet. So, the Keenerpult needs to launch the average Keener, which I estimate as 150 pounds, 700 feet. For the purposes of making the math easier during operation of the Keenerpult the atmosphere will be removed so that air resistance can be ignored. The max distance that a trebuchet can launch something is 2 times the mass of the counterweight divided by the mass of the projectile times the height of the trebuchet. If we use a 12 foot tall trebuchet the mass of the counterweight needed is 4375 pounds. Unfortunately this seems to not be particularly viable as it would require seven full Rockstar Vs filled completely with water and the pivot would likely not be able to support that weight. In conclusion, the Keenerpult as currently imagined will likely never exist.
