Turnstile and Elevator

November 2, 2010

While the rest of the class worked on the turnstile learning about pawls and ratchets and gear ratios

these two tried out the new energy lab crane.

It could be operated by hand generating electricity.

Or it could be operated through the capacitor.

We could see the amount of volts, amps, and watts.

The elevator could go up and down about 22 times with a full charge.
