Member warned to use the homework template for posts in the homework sections of PF.

I have a long question in my assignment with many part answers and I would just like to know if I have answered them correctly as I have spend a lot of time on it. can anyone help?

My Question is:

The component shown in Fig 1 is made from a material with the following properties and is subjected to a compressive force of 5kN.

Material Properties

Young’s Modulus of -200 GN m^-2

Elasticity Modulus of Rigidity -90 GN m^-2

Poisons ratio - 0.32

Q1a. Calculate the stress in:

(i) the circular section

(ii) the square section

My Solution:

Does This Look Correct?

Q1b. Calculate the strain in:

(i) The circular section

(ii) The square section

Does This Look ok?

Q1c. The change in length of the component

Q1d. The change in diameter of the circular section

Q1e. The change in the 40mm dimension on the square section

Q1f. If the same component were subjected to as shown in FIG 2, calculate the shear strain in:

(i) The Circular section

(ii) The Square section

Any help or advice would be much appreciated. Thanks
