1. The state of plane stress at a point is shown on an elelement Fig (a) Fig (a) 4 30ksi 20ksi X o'15ksi (a) Using Mohr's Circle i. Represent this state of stress o, and o, ii. Draw an element showing the maximum shear stress (show the angle with respect to the x- axis) iii. If a crack is going through the element as shown, Fig b, at 60° clockwise.

1. The state of plane stress at a point is shown on an elelement Fig (a) Fig (a) 4 30ksi 20ksi X D'15ksi (a) Using Mohr's Circle i. Represent this state of stress o, and o2 ii. Draw an element showing the maximum shear stress (show the angle with respect to the x- axis) iii. If a crack is going through the element as shown, Fig b, at 60° clockwise.
