Figure Q5 shows few loadings applied on bar ABD. Suppose the diameter of the bar is 120 mm, and knowing that P1, P2 and P2 are 10.a kN, 5.b kN and 15.c kN, respectively. Parameter a, b, and e are given by: a = last digit of your matrix number b = fifth digit of your matrix number c = fourth digit of your matrix number For example, a student with the matrix number CD200187 will have the values of 10.a = 10.7, 5.b = 5.8 and 15.c = 15.1. (a) Calculate the state of plane stress at point H (b) Sketch the element for the state of plane stress in (a) Using Mohr's circle, determine the principal planes, the principal stresses, and sketch the corresponding element at point H (c)

For the First name and Surame please use the N - Z option   First name w(ab) and a(AB) are counter-clockwise   Surname: r(AB) = 500mm and angle = 30 Degrees

Question 8 Let z = g(x, y) = x³ + xy³ + y² - 6x - 2y + 4, where x = r cos (0) and y = r sin(0). Use the chain rule to find at (r, 0) =(√2, Z). Enter an integer or a fully reduced fraction such as -2, 7, -3/4, 41/7 etc.
