Foosball Table (Lever, Screw)

The metal rods that run horizontally across the table work as rotating levers (wheel and axle) to spin the undaunted foosball kickers. With the help of large screws through their backs to keep them firmly fastened to the rods, the acrobatic foosball kickers are able to perform endless backflips with high rotational velocities to send the foosball flying.

Cabinet Locking Setup (Screw + Wedge + Wheel and Axle + Gear)

• A picture of the locking setup for the cabinet in my dorm. Wedges are found behind the door and within the hook of the combination lock. Wheels and axles can be found in the combo lock and where the wedge behind the door can be rotated 360 degrees. Screws attach most of the setup to the door. Gears within the combination lock finish the setup by activating the lock/unlock feature.

Pencil Sharpener, Gears, Wheel and Axle, Wedge

This is a pencil sharpener.  The battery turns a set of gears.  One of the gears has a rod attached to it, making it a wheel and axle.  The rod turns the sharpener, whose blade acts as the wedge.
