If you only learn to design with one mechanism, make it an over centre mechanism. In my opinion, this is one of the most versatile and effective mechanical systems you can utilise. In this video, we look at real world examples, and then break down the characteristics across a series of different designed examples. The final example is a CO2 dragster launcher, and stores enough energy to puncture a canister despite only needing the smallest nudge to activate.
