The state of plane stress at a point is shown in Figure 1. By using Stress Transformation Formula, calculate: i) The principal stresses and their locations. ii) The maximum in-plane shearing stresses and their locations. iii) The normal and shear stresses on a plane making an angle of *5A°. *A is sum (total) of your ID No. (until become a single digit) Example: 20093 = 2+0+0+9+3 = 14 = 1+4 = 5 (Final digit) *If odd numbers (assume the angle is clockwise) *If even numbers (assume the angle is counter-clockwise) (**) If sum of X value is zero (0), use A value. iv) Check your answers in (i), (ii) and (iii) by using Mohr's Circle Method. Show all the values on the graph paper. All the principal values must be clearly written on graph paper.

Transcribed Image Text:The state of plane stress at a point is shown in Figure 1. By using Stress Transformation
Formula, calculate:
i) The principal stresses and their locations.
ii) The maximum in-plane shearing stresses and their locations.
iii) The normal and shear stresses on a plane making an angle of *5A°.
*A is sum (total) of your ID No. (until become a single digit)
Example: 20093 = 2+0+0+9+3 = 14 = 1+4 = 5 (Final digit)
*If odd numbers (assume the angle is clockwise)
*If even numbers (assume the angle is counter-clockwise)
(**) If sum of X value is zero (0), use A value.
iv) Check your answers in (i), (ii) and (iii) by using Mohr's Circle Method. Show all the
values on the graph paper. All the principal values must be clearly written on graph paper.

NOTE:
Enter the values X and Y. Do not multiple the values.
No. (i) to (iii), solution must be written using ball pen.
No. (iv), write you answer on graph paper using ball pen.
