I went online and researched sterling engines

-A sterling engine is a heat operated engine that converts heat energy to mechanical work. The cyclic compression and expansion changes the pressure of the gas which creates a series of events that converts the energy into mechanical work.

Basic parts of sterling engine:


Piston

Heat Source

Cylinder


Unfortunately I did not email the teacher on the parts I would like to buy. However, I did accomplish one of my tasks which was to find youtube videos that provide a video guide on how to create a sterling engine at low cost.

I went to team QSM's page (http://en.wikiversity.org/wiki/Engines/Howard_Community_College/Fall2011/550_QSM) to understand where they went wrong or what went right. I know they followed a video guide from http://www.youtube.com/user/muddymuddymuddmann.

I saw the video and it was very helpful I want to follow muddymuddymuddmans video guide to create my sterling engine


Materials:

Tin can

Hot glue gun

2 CD's

Metal Coat Hanger

Sealant

Made a rough sketch of the sterling engine in google sketch up.


Total time spent in Week 2: 2 hours

Week2 Narrative

[edit | edit source]

Upload photos to wikimedia. Upload video to youtube. Convert all spreadsheets, documents, and presentations to wiki format and create wiki subpage of your page for each of them. Link to them here in a narrative that tells a story. High light the problems (engineering problems) you had and how you solved them.

Week2 Peer Review

Make a google sketch-up design of the sterling engine. Email teacher about parts,materials

Week3 Activities

Compare actual work done to Task3

[edit | edit source]

• Designed a sketch of a sterling engine I want to resemble on Google Sketch Up. I wanted to make a simple design. Had difficulty modeling the metal rod that runs horizontally from one end of the displacer to the other. The metal rod should be bent in 90° angles but sketch up can not extend objects on a smooth surface.

•Total Time Spent: 1.5 hours

Week 4 Narrative

[edit | edit source]

Designed a rough mock up of the sterling engine I want to create. The rough draft includes the displacer, the fly wheels and the cylander. The materials used were a mango juice bottle, tooth picks, cardboard paper, electrical tape, and two CD's. I could not model the crankshaft because of its 90 degree curves. This is goIng to be a problem for when I attempt to make the real crank shaft. The two cylanders are 6cm and 4 cm in length. Total time spent: 45 minutes. I also learned how to use Picasa 3, a google app that stores pictures and documentation so it can be stored online.
