Please use all the given information and solve the question by using a mechanical properties.

The structure shown in Fig. la is subjected to loading P and T. A set of strain rosette is positioned at point A for strain measurement. The orientation of the strain rosette is shown in Fig. 1b. The material properties are given as E = 200 GPa, G = 77 GPa and v = 0.3. If P = 10 kN and T= 250 Nm, find the following: i. The state of stress at point A and sketch the stress element. ii. The principal stress at point A and sketch the stress element. iii. The principal strain at point A and sketch the strain element. iv. The values of each strain gauge (Ea, Eb and ɛc). V. Name one change that can be done to lower the strain value at point A. 50mm 75mm 120 120° T Ø 50mm Ø35mm Fig. la Fig. 1b -----

In the state of loading as made of brittle material tensile and compression fracture values ​​of the exposed arm, respectively. σUT=200 MPa and σUC=800 MPa and factor of safety n=4 as it is; a) First reduce the applied forces to point B, b) By determining the critical point of the critical section and stresses Calculate it and show it on the stress element. c) Calculate the diameter of the AB part according to the Coulomb criterion. Note: Neglect the effect of cutting forces.
