Two 3/8 in thick steel plates are fastened "clamped" together by a 1/2 in -13 UNC bolt as shownin the previous figure (i.e. problem 2). When the plates are initially assembled (i.e. before anexternal load is applied), the bolt is tightened to a torque of 57 ft lb. The "screw coefficient offriction" and the "collar coefficient of friction" are μ = μc = 0.15. The collar diameter d. 1.5d.What maximum external load "F" can be applied to the bolted connection if the minimumallowable clamping force "F" is 2000 lb? The elastic modulus for the bolt is E₂ = 30 x106 psi andthe elastic modulus for the plates is E₁ = 26 x10 psi. (Hint: Use Equation 10.14 Pg 401(Textbook) and Figure 10.28 Pg 402 (Textbook) to determine the bolt stiffness k, and the clampedmember stiffness k. Assume that the threads stop immediately above the nut.)Ans. Fe 6131 lb d₁30°Conical effectiveclamped volumed3-(Hexagonal bolthead and nut)

The figure shows a section of a large coupling. Each bolt in this joint is subjected to cyclic load fluctuating between 0 and 13 kN. The members are made from steel. The members have equal thicknesses and total length of members is L=37 mm. Each bolt is initially tightened carefully to 78% of proof load. The bolt is to be Metric grade 5.8 M12x1.75 (coarse-pitch series). The threads has been manufactured by rolling and reliability for bolts is 95%. Calculate the stiffness of the bolt (in kN/mm).

Problem 17 A joint shown has the basic layout shown in the diagram below. (All dimensions on the diagram are in inches.) A single pin of diameter 0.5 inches (A = 0.2 in2) holds together the yoke and bar as shown. The material has an ultimate strength in tension of 80 ksi, and an ultimate strength in shear of 45 ksi. The load P has a value of 10000 lb. By examining the shear stress in the pin, the normal stress in the yoke, and the normal stress in the bar, find the overall factor of safety for the joint.
