Simple questions regarding stress/force from aluminum bolt?

Hey guys, I just would like to ask simple questions about forces/stress of aluminum bolt to be fastened for connecting aluminum extrusion as shown in diagram above.

1. As shown in the drawing, "A" shows the shear, so what force does B have then?

2. So how would you calculate the shear (A)? Do I just do
ultimate shear strength x 1/2 x cross-section (pi x radius of screw)?

3. So as I mentioned before, I'm using aluminum bolt to be fastened for connecting aluminum extrusion. How would I go about choosing the suitable aluminum bolt?

Hi there,

I would like to provide some insights on the forces and stresses involved in fastening aluminum extrusion with aluminum bolts.

1. In this diagram, B represents the tension force that the bolt experiences as it is being tightened. This force pulls the bolt in opposite directions, creating tension within the bolt.

2. To calculate the shear force (A), you would need to consider the cross-sectional area of the bolt, the ultimate shear strength of aluminum, and the applied load on the connection. The formula you mentioned is a good starting point, but it is important to also consider the specific properties of the aluminum materials being used and any potential external factors that may affect the shear force.

3. When choosing a suitable aluminum bolt for this application, it is important to consider the load and stress that the bolt will experience. The bolt should have a suitable shear and tensile strength to withstand the applied forces. It is also important to consider the compatibility of the aluminum materials to avoid any corrosion or galvanic reactions.

I hope this helps answer your questions. It is always important to carefully consider the forces and stresses involved in any engineering application to ensure the safety and effectiveness of the design.
