The figure shows a steel bearing block that is to be bolted to a steel ceiling joist with 20 mm thick flanges, supporting a gravity load of 40 kN. M24 ISO 8.8 coarse threaded bolts are used with 4.6-mm-thick steel washers under the bolt head and nut. The dimension A, marked in the figure is 22mm. (a) Find the wrench torque required if the fasteners are lubricated during assembly and the joint is to be permanent. (b) Determine the factors...

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...
2. (2 marks) Consider a pre-loaded threaded bolted joint subjected to static load P as shown in the figure below. This figure shows one of the bolts of a threaded joint that is part of a group of uniformly loaded bolts. The bolt is a SA Grade 4 bolt having a major diameter d0.375 in and the pitch p - 0.0625 in. The two steel members, marked 2 and 3 in the figure below, have the thickness of 0.5 in...
please just do #1 1. The lid on a pressure vessel is held down with 10 bolts that pass through the lid and a flange on the pressure vessel (similar to example 8-4, in the text). The bolts are secured with nuts under the flange. There are no washers. The thickness of the lid is 28 mm and the thickness of the flange is 28 mm. The vessel and lid are both made of steel. The vessel is pressurized to...
