Question: bla a rectangular steel plate of sides 150 mm ...

Question details

BL(a) A rectangular steel plate of sides 150 mm × 100 mm is stretched as shown in Figure QBla. Caleulate the change in the area of the plate as a result of the applied stresses (Take Youngs Modulus, E-200 GN/m2 and Poissons ratio, v-0.3) (8 marks) 30 MN/m 45 MN/ 45 MN/m 30 MN/m2 Figure QBla (b) At a point in a strained material the stresses acting on planes are shown in Figure QBlb. By using either direct calculation or Mohrs circle method, determie: ơ,--10 MN/m2 y 20 MN/m2 = 32 MN/m2 o, 32 MN/m2 a,- -10 MN/m EigureOBİb 0 the maximum and minimum principal stress (4 marks) (the angles of the principal planes relative to the plane carrying the 32 MN/m (3 marks) stress measured in counter-clockwise direction; (iii) the maximum shear stress; (2 marks) (iv) the angles of the maximun shear stress planes relative to the plane carrying the 32 MN/m stress in (3 marks) ss measured in counter-clockwise direction.
