Standard design practice, as exhibited by the solutions to Probs. 8-66 to 8-70, is to assume that the bolts, or rivets, share the shear equally. For many situations, such an assumption may lead to an unsafe design. Consider the yoke bracket of Prob. 8-61, for example. Suppose this bracket is bolted to a wide-flange column with the centerline through the two bolts in the vertical direction. A vertical load through the yoke-pin hole at distance B from the column flange...

5. The figure shows a cast-iron bearing block that is to be bolted to a steel ceiling joist and is to support a gravity load of 18 kN. Bolts used are M24 ISO 8.8 with coarse threads. The joist flanges are 20 mm in thickness, and the dimension A is 20 mm. The modulus of elasticity of the block is 135 G Pa. Find the safe tensile shear load F that can be applied to this connection to provide a...

131- (3 marks) Figure below shows a bolted joint subjected to an external force P that fluctuates from 0 to 7 kips. The steel bolt specification is 5/8"-11 UNC, SAE grade 5 material with rolled threads. The clamped members are steel of length 1.25 in each (with a total length of 2.5 in). Plain wide washers are utilized at both ends of the bolt. [a]. Using the Goodman line, determine the factor of safety guarding against fatigue failure for the...

Required information For a bolted assembly with six bolts, the stiffness of each bolt is kb=1.8 Mibflin and the stiffness of the members is km=16 Mlbflin per bolt. An external load of 80 kips is applied to the entire joint. Assume the load is equally distributed to all the bolts. It has been determined to use 1/2 in-13 UNC grade 8 bolts with rolled threads. Assume the bolts are preloaded to 75 percent of the proof load. Determine the yielding...
