School of Science and Engineering Al Akhawayn University Test 2 Egr3402, Fall 2004 Instructor: Dr. H. Darhmaoui Duration: 80 min. Problem 1: (40 marks) A Pratt roof truss is loaded as shown. Using the method of sections, determine the force in members FH, FI and GI Problem 2: (30 marks) Determine the moment of inertia and the radius of gyration of the shaded are shown with respect to the x and y axes. Problem 3: (30 marks) Block B starts from rest and moves downward with a constant acceleration. Knowing that after slider block A has moved 400 mm its velocity is 4 m/s, determine (a) the acceleration of A and B, (b) the velocity and the change in position of B after 2s Date: November 19, 2004
