Inverted Pendulum - Reciprocating Saw

Purpose:

To give students an awareness of other non-intuitive solutions to the equation of motion for a driven pendulum.

Procedure:

Reciprocating Saw Driven Setup:
Start out by holding saw in one hand and pendulum ruler stick up with other hand. Get saw running by pressing trigger (variable speed).
