Talk:Shear strength

Untitled

While this is a decent start towards describing shear stress, it is ambiguous at best. I don't have the time to edit this page personally, but if someone else does decide to pick up the cause, I would make 2 recommendations that would clarify a great deal.

create a picture describing the forces and labeling the planes they are in. The formulas listed could easily be mistaken for axial stress equations since the directions of the forces are not mentioned.
Check out "Mechanics of Materials" by R.C. Hibbeler. It's a great resource for this topic. Section 1.5 is particularly pertinent. It was the textbook of choice when I got my Mechanical Engineering degree back in 2004.

Quick note, sigma2 is intermediate principal stress, sigma3 is minor principal stress. Could I please get confirmation of this. —Preceding unsigned comment added by 131.251.143.253 (talk) 13:57, 15 January 2009 (UTC)[reply]

tau = F * S / (I * t)

I learned this formula for shear stress. The results are a little bit different. —Preceding unsigned comment added by 145.253.148.26 (talk) 07:10, 19 April 2011 (UTC)[reply]

Approximate Strength Table

This table's values don't match up with much of what I've seen elsewhere online, people generally report 0.5, 0.577, or 0.6 x UTS as the Shear Strength value. Also the link is deprecated so can't be reviewed. One sample mentioning 0.6 is https://www.portlandbolt.com/technical/faqs/calculating-strength/ — Preceding unsigned comment added by 14.2.224.5 (talk) 03:20, 19 December 2019 (UTC)[reply]

Average Shear Stress

I did a minor change by adding a sentenced saying of to measure shear strength. I plan on adding an equation for average shear stress and moved it along with the other equations to a new section. I also want to improve the comparison section so I plan on removing the first table and replacing it with information from https://www.portlandbolt.com/technical/faqs/calculating-strength/. — Preceding unsigned comment added by NKrop (talk • contribs) 02:52, 14 February 2020 (UTC)[reply]

Diagram Needing Improvement

The diagram is confusing and possibly not correct. The diagram speaks of the force but does not show the force vector. It then goes on to show the shear denoted by tau with a direction, but shear is a pressure and not a force. Either the caption needs clarification or the diagram needs updating.
