Question

1.52 Solve Prob. 1.51, assuming that the structure has been redesigned to use 16-in.-diameter pins at A and C as well as at B and that no other changes have been made. A in. 8 in. B C 4 in. 6 in. Fig.P1.51 1.51 Link AC is made of a steel with a 65-ksi ultimate normal stress and has a 2-in. uniform rectangular cross section. It is connected to a support at A and to member BCD at C by-in.-diameter pins, while member BCD is connected to its support at B by 16-in.-diameter pin. All of the pins are made of a steel with a 25-ksi ultimate shearing stress and are in single shear. Knowing that a factor of safety of 3.25 is desired, determine the largest load P that can be applied at D. Note that link AC is not reinforced around the pin holes. a 1.52 Solve Prob. 1.51, assuming that the structure has been redesigned 16-in.-diameter pins at A and C as well as at B and that no to use other changes have been made. 1.51 and 1.52 1.29 Two wooden members of uniform cross section are joined by the simple rectangular glued scarf splice shown. Knowing that P 15 kN, determine the normal and sharing stresses in the glued splice. in. 8 in. P 150 mm -4 in.- 6 in. 45° Fig. P1.51 75 mm Fig. P1.29 and P1.30
