P1: Build a mechanical car launcher #

Design, prototype, and refine a mechanism that can reliably hold and release a toy car with enough force to launch a toy car through a hoop.

The goal here is threefold:

1. design a means to control a large force from a rubber band with a small force from your finger
2. validate your design with mathematical estimates
3. practice building a smooth mechanism

You will be given: #

• 1 ball bearing, 8 mm OD, 3 mm ID, 4 mm width, part number 693ZZ
• 1 piece of steel rod, 3 mm in diameter
• A pile of rubber bands, size 64
• 1 toy car for propulsion

You will need to obtain: #

• Probably some cardboard for prototyping
• Probably some plywood from the Nolop store for laser cutting
