Thanks for the replies I think i get the point.But given with the task of designing the bolts and dowels how can I go about it ?.I think I'm asking a lot here but I just need the picture or idea to start with.To learn this design I thought i can first size the dowel and bolt and I can check...

Sorry missed the attachment in last post.

Hi all, I just started learning engineering mechanics this semester,so what I'm about ask may be a basic question in the subject.I came across a bracket that is used in a industrial equipment (i have attached a sketch as image).The bracket is used to mount a hydraulic cylinder.The cylinder has...

Hi all, This is a question regarding stress and strain. Can someone please explain the concepts of stress and strain in atomic level? My understanding is as follows.Let us consider a metal bar or rod that is subjected to tension.The load applied to the bar will be try to elongate the...

Is my question confusing ? .Or am I asking something very basic?.Please reply so that I can improve

Is my Question very elementary or unclear?I asked this question to my professor but the reply he gave was not very convincing.It was the reason I posted the question in this forum.I could understand something from the first reply,But still I'm not completely clear with this.So Please help me in...

Thanks tim Sorry for late reply. I'm still hung up on this topic.(I'm learning calculus and I understand some basic concepts of it).Sorry for repeating the question again. Still my question is if I take a rod under uni axial tension, will the stress be different for cross section cut at...

Is my question unclear or am i asking something that doesn't make any sense? .Please correct me if I'm missing something so that i can improve. Thanks in Advance

Hi all, I have a very basic question regarding the topic of stress.While deriving the equations of equilibrium for a plane element,there is a concept called incremental stress.That is,if stress in the x direction for one face is σx the stress in the opposite face is σx + (δσx/δx)*dx. Where the...

Hi all, I have started with my understanding of pressure vessels and i have some queries on the topic. 1) I understand the part of axial stresses.When a cylinder capped at both ends is subjected to internal pressure,it tends to increase the length of the shell,and therefore a resistance is...

What I'm about ask is very basic.But I don't understand one thing.In the image the thread starter has shown,the points A and C are connected through B so if the load applied at B tries to push it down will the point C remain stationary because of the reaction offered by X component of A ?.If the...

I did not mean the algebric difference between CSA and projected area,I wanted to know why conceptual difference between both.If Projected area is d*t and there is clearance between the hole in the fork and pin (Which there should be),the contact will take place only over some arc length.My...

Hi all, I today learned that for pin design there is a parameter called,crushing stress,where the pulling force of the fork is divided over projected area,I learned that projected area was d*t where d was the diameter of the pin and t was the contact length between pin and the fork being...

Hi all, This is my first post in PF I'm doing my ninth standard in India,My knowledge in physics is limited so please forgive me if I ask something basic Can anyone clearly explain me the relationship stress and strain,because I thought when a material deforms (even to the slightest...
