For the state of stress shown on the element below, Apply the concept of stress transformation to determine: (i) Using analytical method of transformation equations; (a) The orientation of principal planes and the values of max, and min. principal stresses. Also sketch the principal planes on a rotated stress element along-with the max. and min. principal stresses on the respective planes. (b) The orientation of max. in-plane shear stress and the values of max. and min. in plane shear stresses. Also sketch the max./min. in-plane shear stress planes on a rotated stress element labelled with the respective stresses on the planes. (ii) Using graphical method of Mohr's stress circle technique; find the normal and shear stresses on an inclined plane as shown in the figure below. |(R) MPa YA → (1.6R) MPa 350 (1.2R) MPa

Measuring is the comparison of a particular physical quantity with its reference value. A unit is a fixed physical quantity. The length is a physical quantity. A physical quantity is the product of a unit and the numerical value we need to compare with.
