    Spring Positioning on a Cantilever beam

    @paddingtongreen the Spring is a known spring of e.g K=500. if i were to lay out an iteration process, How would i go about it?...cause actually, i have to do the problem for varying thicknesses of my beam which correspond to the different spring constants.am trying to work it out in MS Excel...

    Spring Positioning on a Cantilever beam

    Hallo guy, I hope its not asking too much, but i really need help with this, Urgently. I have a cantilever, with point load P=100 at the end tip. A spring(K=500) attached to the cantilever perpendicularly at UNKNOWN position. I KNOW the deflection at the end tip. and the rest of the parameters...

    Bending and Torsional stiffness of Closed Profile hat/Omega stringer

    Hallo Engineers, I am a little bit confused here and i need some guidance. Can any of you educate me on how to calculate the Bending and Torsional stiffness of a Hat/Omega stringer attached on a plate to form a fuselage panel?..You can also recommend to me a book where it is clearly described so...

    Tapered portal frame Analysis

    hallo everyone, My friend is working on a Portal Frame analysis and he was asking me some questions which i didn't know how to answer,it would be great if you can highlight me on some. so the question is: How do you go about with Analytic solution for a Tapered portal frame?,and how is it...

    cantilever problem.

    @ rb1957 and IDS, Sir, so, i guess a general Analytic solution is hard to come by?....cause have really tried it in and out but still not working out. the beams surely have the same section. my other idea is to try and find the force acting at the junction but the problem is, the force acting...

    cantilever problem.

    the x-axis beam is 40cm while the z-axis one is 15cm. i think the lengths of the beams should not be that relevant, we can choose them arbitrarily BUT sure, to generate the displacement value that i gave, you need them.

    cantilever problem.

    @ rb1957, Sir thanks for your constant reply, i really appreciate it a lot. The second question was without the spring. I have attached a file, if you have some time, you can have a look at it and give me clue of the way forward. N/B the material is Allum hence E= 70GPa. am looking forward to...

    cantilever problem.

    @rb1957 and GregLocock, or (anybody else who has an idea with the approach) i have another issue concerning deflections, lets say that the beam specified above is connected to another beam which lies on Z axis (Z axis, is the axis that is facing you) at an angle of 90 degrees. Meaning that both...

    cantilever problem.

    @ GregLocock, why is the deflection due to the influence of the angle so high?. this part of the formula (2L/3*alpha)...lets say that my 2/3 of L is 25. its generating a very big deflection at the tip

    cantilever problem.

    hallo everyone, I have a cantilever with a point load at the far end e.g 10N and a spring of know stiffness e.g 100 N/m attached perpendicular to the beam at 1/3 of the beam from the fixed point. can somebody please help me know how i can calculate the deflection at the cantilever tip. I will...

    some papers or Books which cover Aircraft Stringers in details

    Hallo everybody, can somebody recommend me a book or any article which covers Aircraft stringers in details, specially the Omega/hat Stringer. I will highly appreciate. Am doing some documentations and i need a lot of literature to go through. Thank you in advance. Hawkins
