Construct and Test Prototype
For most of my constraints I made a peg on one object and a hole on another object. Then I just used the insert constraint so that the pieces could spin in a direction in the object like it is screwed in. The only other constraint I used is symmetrical on my antlers so that they looked good.
The only degree of freedom is the objects ability to spin in its insert. I don't know why the antlers have all of the arrows because when I checked they didn't move except spin. So 5 of the 6 Degrees of Freedom were removed.
Evaluate the Solution
My final design before modifications fit all the constraints except the withstanding 50 pounds. So I had to make minor length and width changes to the body and the legs. The Body was made longer to make more weight since the legs were shortened and the deer originally only weighed 109 pounds
In the process of trying to get within the 50 pounds of force constraint I had to make the legs of the deer wider.
After these minor changes I was able to fit all the criteria and still be within the weight and was 3 pounds over the minimum of 50 pounds of tipping force required.
Present the Solution
This model is efficient because it is a solid piece of wood that is close to 125 pounds and withstands 53 pounds of tipping force. Through this project there was flaws in this model but I feel that they were all correctly fixed and modified to the correct standard they needed to be. The construction of it on the grid was correct from the start so there was no calculation error or weight errors because of an incorrect center of gravity. The economic and environmental condition for this object is fine because there is plenty of wood that is not recycled and is cheap so that is economically good and environmentally so that there is no unneeded burning of wood happening or it going to dumps. In all the other consideration this model will not have a huge impact, but I can say it is safe, easy to manufacture and feasible and sustainable for anybody. Through the project I used 2 new constraints in Inventor and that's it. I figured out how to use the insert and symmetrical constraints.
