Problem 2 The two-bar truss ABC shown in Fig. has pin supports at points A and C, which are 2.0 m apart. Members AB and
BC are steel bars, pin connected at joint B. The length of bar BC is 3.0 m. A sign weighing 5.4 kN is suspended from
bar BC at points Dand E, which are located 0.8 m and 0.4 m, respectively, from the ends of the bar.
Determine the required cross-sectional area of bar AB and the required diameter of the pin at support C if the
allowable stresses in tension and shear are 125 MPa and 45 MPa, respectively. (Note: The pins at the supports are
in double shear. Also, disregard the weights of members AB and BC.)
