A beam is made up by bolting together two cold-drawn bars of AISI 1018 steel as a lap joint, as shown in the figure. The bolts used are ISO 5.8. Assume the bolt threads do not extend into the joint. Taking F=2.8kN and Ignoring any twisting, a) Identify the bolt with the larger shear force and find that shear force. b) Determine the factor of safety of that bolt using Maximum Shear Stress. c) Assuming the beam is made of steel with yield strength of Sy=360MPa, find the factor of safety based on bending stress in the beam

Step 1
Given that the force F = 2.8 kN acts on the beam, and assuming the bolts are symmetrically placed with respect to the force application point, the shear force in the bolts will be distributed equally if the geometry does not suggest otherwise. However, without a Show more…

A composite beam is constructed by bolting four plates to four $60 \times$ $60 \times 12$ -mm angles as shown. The bolts are equally spaced along the beam, and the beam supports a vertical load. As proved in mechanics of materials, the shearing forces exerted on the bolts at $A$and $B$ are proportional to the first moments with respect to the centroidal $x$ axis of the red shaded areas shown, respectively, in parts $a$ and $b$ of the figure. Knowing that the force exerted on the bolt at $A$ is $280 \mathrm{N}$, determine the force exerted on the bolt at $B .$

The horizontal rigid beam ABCD is supported by vertical bars BE and CF and is loaded by vertical forces P1 = 400 kN and P2 = 360 kN acting at points A and D, respectively (see figure). Bars BE and CF are made of steel (E = 200 GPa) and have cross-sectional areas BE = 11,100 mm² and CF = 9,280 mm². The distances between various points on the bars are shown in the figure. i- Determine the deformation in each of the bars BE and CF. ii- Hence determine the vertical displacements of points A and D. iii- If the temperature of both rods BE, and CF is raised by 100°C, determine the new vertical displacements of points A and D. Will the forces in rods BE and CF change due to the rise in temperature? Neglect the weight of the rigid beam. Take E = 200 GN m⁻², and α = 12 x 10⁻⁶ K⁻¹
