Points awarding system
For this assignment, points for chosen and calculated values will be based on a scoring system that assigns the highest marks for values closest to the correct answers and zero for values with an error of 50% or more. Each question's score is also weighted based on an engineering approach which will only be revealed during the feedback session.
Information
TUT Test Setup 2018-08-21: In this image below, the ruler 0 (mm) was held as close as possible to the tip of the beam. Take some error due to parallax into account.
The TUT volunteers took these measurements:
UP Test Setup 2018-08-22: In this image below, the ruler 0 (mm) was held as close as possible to the tip of the beam. Take some error due to parallax into account.
The UP volunteers took these measurements:
Chosen dimensions:
PLEASE insure you provide the values in the REQUIRED UNITS indicated below, NOT in the units of your choice!

DO NOT enter the units or any other text, only the values required.

Please use a decimal point when supplying real values, NOT a comma, otherwise your values won't be processed.

Also note that choosing the correct dimensions is your responsibility. You need to apply engineering judgement. There was only 1 physical setup, therefor simply using any set of measured values are irresponsible. Consider your test and hand calculation results as well.

Your answer
Under a 3kg load, Deflection [mm] at distance b:
Please note: NOT the tip deflection. Provide the deflection at the point where it was measured.
Only submit POSITIVE values throughout this assignment.

Your answer
Which input value do you believe had the biggest impact on the calculated deflection? *
Which input value do you believe had the least impact on the calculated deflection? *
Which input value do you believe had the biggest impact on the calculated stress? *
Which input value do you believe had the least impact on the calculated stress? *
If this material yields at 300MPa, under what mass (when loaded at the same location as in this experiment) will the material start to yield at the highest theoretical stress location? [kg]
Your answer
For the above case (when the material start to yield), what will the tip deflection be? [mm]
Your answer
For bonus points: Why (if so) was noting down the strain and deflection values for the lower applied masses useful if we were only interested in the values under the 3kg load?

Your answer
Not for marks: Please list any questions you have which you would like answered in the feedback session.
Your answer
Not for marks: Which FEA software did you use to complete the assignment? *
Just out of interest
Not for marks: Any comments about the software you used? *
E.g. why you used it?, was it easy to use?, what should be improved about it? etc.
