For my 3d print project, I created an elevator problem, I used question #4 from page 173 on energy and efficiency.

Description:

I printed out an elevator, a little person to go inside and a pulley machine to represent how the elevator moves. I used a painted bottle cap to represent the electric motor. I then used a string to attach everything together and allow for the elevator to move. I glued my project onto a piece of wood with the question and solution written on the extra space.

Why I chose this question?

I choose this question because I wanted something fairly complex but also easy/simple to print. For me, Elevator questions were always difficult so I choose that to challenge myself.

Question:

Question: An 8.5 x 10^2 elevator is pulled up at a constant velocity of 1.00m/s  by a 10.0kw electric motor

What is the efficiently?

Answer: 83,3%

(Work on physical copy of project)

Design process / Progression

I first created a cube on Tinkercad, I used the hollow tool to make it more elevator like.

I then created a pulley machine, which I separated into different pieces to allow it to print correctly.

I printed the project and glued it together.

I attached it to a piece of wood creating my final design.

Things I found difficult

At first I did not realize how small my project would print as, I still managed to make it work even though it was a little smaller then expected.

Because my pulley machine was separated into multiple parts, gluing them together was difficult because they wouldn’t stick.
