    Direction Shear
Click For Summary
The discussion centers on the concept of double shear and its directional implications in relation to forces acting on a pin. The forces Rbh and Rbv create horizontal and vertical shear stresses, respectively, leading to a resultant force that may cause the pin to shear in the direction of this resultant rather than strictly horizontally or vertically. Participants explore the physical interpretation of bearing and shearing stresses, questioning their significance and the contexts in which they should be calculated. The conversation highlights the complexity of shear forces and the importance of understanding internal stresses in materials. Overall, the dialogue emphasizes the need for clarity on how resultant forces influence shear direction in practical applications.

i recently came across a problem which has raised a question in my mind...

heres the link to it

http://www.mathalino.com/reviewer/m...aterials/solution-to-problem-119-shear-stress


the Rbh force tries to shear it horizontally while the Rbv tries to shear it vertically.so here in the solution the resultant of these forces is taken.so does it mean that in reality(physcially) the pin will shear IN THE DIRECTION of this resultant force?not tangentially as in the case of horizontal or vertical?

thank you.
 
Engineering news on Phys.org
What on Earth do you mean by shear tangentially?

Since the arms have weight the pin may well shear horizontally in reality.

However as noted both Rbh and Rbv act across the same areas and so, therefore does their resultant.
 
sir..are bearing and shearing stresses part of internal forces/loads?
 
Think of a material element in the pin and using the reaction load son the pin to find the principle stress.
 
yes but i want to know the physical intrepretation of these two stress..why are they important.when do we need to calculate them..
 

Thread 'UV filter for home central heating?'

Had my central air system checked when it sortta wasn't working. I guess I hadn't replaced the filter. Guy suggested I might want to get a UV filter accessory. He said it would "kill bugs and particulates". I know UV can kill the former, not sure how he thinks it's gonna murder the latter. Now I'm finding out there's more than one type of UV filter: one for the air flow and one for the coil. He was suggesting we might get one for the air flow, but now we'll have to change the bulb...
