Document Summary
Students must count the number of pages in this examination question paper before beginning to write, and report any discrepancy immediately to a proctor. The aluminiumf supported at b, d has a taut stainless steel wire connected at a and c. using the unit load method, det loy frame abc shown in figure q 1 is pin-jointed at a, simply. //111~ ine the horizontal deflection of point c when f = looon and. The mechanical apd area properties of the frame abc and the wire ac are listed below. The pin-jointed t ss system shown in figure q2 consists of uiiiform bars made of an aluminium alloy with the same areas of cross section a = 25 mm2 and length l = 0. 5 m. The young"s mo ulus of the aluminium alloy is 68 gpa. Detennin the global stiffness matrix for the system. Apply th boundary conditions to obtain the resultant system of equations, in matrix fo nodes.
