The document contains 8 multiple choice questions related to engineering concepts. Question 1 asks about the definition of a skew symmetric matrix. Question 2 asks about calculating the gradient of a scalar function. Question 3 asks about the singularities of an analytic function. Question 4 asks about calculating hoop stress in a cylindrical pressure vessel. Question 5 asks about the modulus of rupture of concrete related to its compressive strength. Question 6 asks about the term used for the ratio of plastic moment to yield moment in plastic bending theory. Question 7 asks about partial safety factors for design strength of concrete and reinforcing steel. Question 8 asks about the point through which the resultant of external loading must pass to ensure pure bending without twisting.
