Cantilever beam with curved beam on the end.

In summary, the conversation discusses how to calculate the deflection of a beam made up of two attached beams, one being a straight cantilever and the other a 90 degree bent beam. The load is applied on the open face of the bend and the process involves calculating the bending moment and displacement of each part separately before combining them to get the total displacement. However, it is noted that this method may not provide an accurate answer as the straight portion of the cantilever also experiences rotation at its tip, causing additional deflection of the curved portion.

struggling to find info on this so figgured i'd as.

For two beams attached to each other, one a straight catilever and the second a 90 degree bent beam attached to the end of the cantilever (shown in attached picture). To calculate the deflection of the beam at the load applied, given the load applied is on the open face of the bend.

Would you consider each part seperatly?
so for the curved beam calculate the bending moment applied to that relative to the assumption that the straight part of the beam is fixed in position, then calculate its displacement.

Then apply the same bending moment to the canilever calculate its displacment.
To get the total displacement add the compenents of the cantilever and the bend together to get its final position?

That would not give you the right answer because the straight portion of the cantilever also rotates at its tip causing an additional rotation and deflection of the curved portion.
 

1. What is a cantilever beam with a curved beam on the end?

A cantilever beam with a curved beam on the end is a type of structural element used in construction and engineering. It consists of a horizontal beam that is supported at only one end, with a curved beam attached to the free end. This design allows for the transfer of loads and forces to the supporting structure.

2. How is a cantilever beam with a curved beam on the end different from a regular cantilever beam?

The main difference between a cantilever beam with a curved beam on the end and a regular cantilever beam is the shape of the free end. A regular cantilever beam usually has a straight end, while a curved beam allows for a more gradual transfer of loads and reduces stress concentrations.

3. What are the advantages of using a cantilever beam with a curved beam on the end?

There are several advantages to using a cantilever beam with a curved beam on the end. These include increased stability and strength, reduced stress concentrations, and the ability to transfer loads more efficiently. Additionally, the curved beam design allows for a more aesthetically pleasing structure.

4. What factors should be considered when designing a cantilever beam with a curved beam on the end?

When designing a cantilever beam with a curved beam on the end, several factors should be taken into consideration. These include the expected loads and forces, the materials used, the structural integrity of the supporting structure, and any potential environmental factors such as wind or seismic activity.

5. What are some common applications of cantilever beams with curved beams on the end?

Cantilever beams with curved beams on the end are commonly used in various construction and engineering projects. Some examples include bridges, balconies, roofs, and canopies. They are also used in the design of specialized structures such as arch bridges and arch dams.
