Thanks FEAnalslyst and Lnewqban for your responses confirming my understanding. I agree if it were a vibration problem then the point mass at end would contribute to inertia and lead to different natural frequencies. Thanks again 😊😊👍👍

Hi all, I was looking for help with obtaining deflection at end of a cantilever beam with point load at end as well as point mass at the same location. I believe it would be exactly same. Is this correct? That is, I think just adding point mass at the cantilever's end wouldn't change the...

Hi, One is learning about experiments: I guess for that 101 science experiments is good... Other is learning the theory: for that a good starting point may be Conceptual Physics - Paul Hewitt

Ok...so the thing is if you are new to ansys, just like vb or excel macro recording, Ansys also records everything you do using a GUI. So just apply the forces manually a couple of times first. Solve the model the number of times you applied the forces and get the results. Follow the process you...

I am not very sure how to derive the mathematical equation for the stress field. But the way I would follow is to first look at and understand how the equations for simple supported circular plate with point load at the center are derived from first principles. What this will do is to give you a...

Thanks :)

Thanks for your replies. I got some thoughts on this today. Description of the whole phenomena according to my understanding is following. Please correct me if you find anything inaccurate. 1. The raindrop forms by condensation of water vapor and starts to fall. Thus as soon as it is formed it...

Hi all, This question just occurred to me: Whether a falling raindrop in presence of a uniform horizontal wind (ideally speaking) has a curve trajectory or a straight line? Assuming the wind force is constant, the velocity of the raindrop in horizontal direction will keep on changing since there...

Thankshttps://www.physicsforums.com/members/e-bar-goum.246096/'][/PLAIN] e.bar.goum and Ryan for your inputs. I think that I will go ahead with it anyway. I have thought to give preference to universities which have their requirements to be completed in 3-4 years. I think this might spare me...

Hi, I once considered myself enough to be decent enough to solve some problems but lately I'm thinking to revisit and start solving problems again. I would like to know whether there is a book good which has problems (starting from basic to tough ones) for practicing free body diagrams. The book...

Hi all, I am a mechanical engineer 26 yrs old from India. I am thinking to go for a PhD (in US, maybe) but there seems to be a problem! By the time I get started with it I will be 27yrs. And on top of that I will have to be away from my parents for ~6yrs. My parents would do well without me...

[SIZE=17px][FONT=UICTFontTextStyleBody] Thanks Jake for taking time to go through the post and your great inputs :) Really helpful advice . Thanks Haraq for the motivation :) What I feel is because I am confused about what to do I am never really able to focus on my job. Thus my performance is...

Hi all, This has really been a difficult question for me to get through. So I need your help. I'm feeling like the walls are closing in and I need to find out what I want to do for the rest of my life~40 years more. I am an engineer in mid 20's with a master's degree in ME, working for a MNC...

Hi all, I was just reading about airplane flaps. From I what I understood, they increase lift and drag (at lower speeds) to help land the aircraft. Do flaps also reduce the tendency of flow separation at lower speeds? Let's say we have an airplane wing with no flaps (Case I) and airplane wing...

Hi all, I am confused about the terms: Vibration, oscillation and waves. Is vibration and oscillation same or are they different? My understanding is vibration is associated with flexible/deformable bodies and oscillation for rigid bodies. Waves not really having an idea! Any examples of...
