What kind of forces does a chain of a child's swing use? tension, compression, torsion, or shear?

Question

And also, what about a gymnastic balance beam.

Answer 1

The swing chains could be replaced by a rope. The reaction force in either one is principally tension. However, when you analyze the contacts between links, the end links and the attachment, there will be compressive (crushing ) forces principally involved. This goes for knots in the rope too.

A balance beam (a simple beam) is more complex. There will be internal shear, compressive and tensional forces. In the analysis of beams there are shear and moment diagrams, but the moment is not torsional ( rotational twisting) but it is bending, like with a diving board (which is a cantilever beam ).

Answer 2

In a swing, the chain or rope itself is in tension. The end points, or where its attached is a different story, this would typically be in shear. A balance beam like that used in gymnastics is in compression along the top of the beam, while the bottom of the beam is in tension, when someone is standing on the beam in between the supports. But it will change depending on where the person or force is relative to the legs of the beam.

Answer 4

For any given area on an element, the guy stresses are summed making use of vector algebra, then converted into critical stresses. From there, incredibly some failure standards may be utilized, such by way of fact the von Mises yield criterion.
