What models/theory were these moduli used to analyse and how do these models apply to the available experimental equipment?

. With reference to the theory covered in your unit and the available experimental equipment, select suitable models/formulas and develop an experimental method to determine Young’s Modulus and the shear modulus.

Notes:

Theory

•   Where have you studied Young’s modulus and the shear modulus in this unit? Recall beam bending and the torsion of shafts.
•   What models/theory were these moduli used to analyse and how do these models apply to the available experimental equipment?

  Method

•   Refer back to the labs that you have already completed for examples of methods
•   How many measurements will you need to take for a thorough analysis?

2. Carry out your experiments in the allotted lab time and gather the required data.

Notes:

 Remember time is limited ensure you have a clear idea of what you need to record and how many times.

3. Analyse the data and determine the two moduli using the selected models/formulas in objective 1

Notes:

•   What type of analysis will give you the information required to meet the objective?
•   What types of analysis have you used in other lab sessions? Think about tabulated data and

  graphical analysis of your measured data.

4. Compare your findings with published data/standards for the given material
