Finish kinetic

HW:

We accidentally had one more week to work on our zoetrope. For this week, we iterate on the 3D printed pedestal, handle, and support to the point that they worked perfectly without adding the cylinder on top. When we tried to attach a paper plate to the support, however, did the whole system require much more force to actuate. We speculated that this could due to either the increase of air friction, or of angular momentum.

Measurement Project Ideas:

• Potentially reusable energy in the gym:

Unlike working out outdoor, people usually use equipments like elliptical machine indoor, which could potentially be turned into power reserving gateway

Gyms are going ‘green,’ but are they actually eco-friendly? Here’s what to look for.

• Solar energy waste in the apartment household environment

Class Note:

Capacitor vs battery: significantly more charge/discharge cycles, no chemical reaction, charge/discharge fast, high efficiency, higher power (energy/time).
