Name: ______________________________________ Section: __________ Problem 1: The rigid bar AB shown in Fig. 1 is supported by a steel rod AC having a diameter of 20 mm and an aluminum block having a cross-sectional area of 1800 mm 2 . The 18 mm - diameter pins at A and C are subjected to single shear. If the allowable stress for the steel and aluminum is (_ st ) all = 340 MPa and (_ AL ) all = 35 MPa, respectively, and the allowable shear stress for each pin is _ all = 450 MPa, determine the largest load P that can be applied to the bar. (Disregard the bearing stress near pins A & C).
