Chapter 1.5, Problem 52P

Solve Prob. 1.51, assuming that the structure has been redesigned to use 5 16 -in.-diameter pins at A and C as well as at B and that no other changes have been made.

1.51 Link AC is made of a steel with a 65-ksi ultimate normal stress and has a 1 4 × 1 2 -in. uniform rectangular cross section. It is connected to a support at A and to member BCD at C by 3 4 -in.-diameter pins, while member BCD is connected to its support at B by a 5 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.

B The steel tie bar shown is to be designed to carry a tension force of magnitude P = 120 kN when bolted between double brackets at A and B. The bar will be fabricated from 20-mm-thick plate stock. For the grade of steel to be used, the maximum allowable stresses are: o = 175 MPa, ↑ = 100 MPa, o, 350 MPa. Design the tie bar by determining the required values of (a) the diameter d of the bolt, (b) the dimension b at each end of the bar, (c) the dimension h of the bar.
5. Three wood boards, each 3.5 in. wide, are joined by the 3/4-in.-diameter bolt. If the working stresses for wood are 750 psi in tension and 1450 psi in bearing, find the largest allowable value of the force P. ² 1 in. P 2 in. P 1 in. T in.
QUESTION 2 Consider that x = 2.76 ft and y = 7.01 ft. B The 5.7-in diameter steel shaft AB is attached into the rigid wall at C and supported by a smooth bearing at A. The lever AC is welded to the end of the shaft. The maximum allowable stress for shaft AB is 355 psi. Determine the maximum allowable force P in lbs. C
