Hello the forum; I am brand new here so I beg you indulgence. How do I calculate the amount of weight a pipe will support if used in a cantilever cituation?

[SOLVED] Cantilever Investigation 1.Hi, I am writing a report on cantilever oscillations, my experiment involves fixing different cantilvers e.g. a ruler to the end of a table then measuring the period and height of oscillations while varing the mass attached to the cantilever, and other...

Homework Statement as a project we need to build a cantilever structure out of newsprint, thread, and masking tape. It can only weigh 350 grams and has to support 1 kilogram, and must stretch 12 inches off of a surface. We have an idea, but we don't know how to make it stronger while keeping...

I am working on the development of an instrument which can be simply thought of as a cantilever tube. This tube is instrumented with strain gauges to measure the X/Y strains and two sets of rosettes, each consisting of two strain gauges at 45 degree. Note that the X/Y are 3-wire half bridge and...

Hello! I have a problem and if anyone could help that would be great. Imagine that you have a cantilever beam of length L and has an end mass m. In order to calculate the natural frequency I use the equation: f=(1/2*pi)*SQRT(3EI/mL^3). a) The moment of inertia in the equation is the sum...

Due to complications I have with drawing and uploading pics at the moment, I'll simply describe the model instead of posting a pic; it's a cantilever beam (ignore the cross section and modulus of elasticity given in the pic, and the force P) of length L = 1, the coordinate axis x is along the...

Hi everyone, I've just started to use COMSOL for the study of a simple cantilever beam and I'm facing some problems while calculating the eigenfrequencies and the frequency-response. I use the 3D MEMS Module>Solid, Stress-Strain. I create a 500e-6,100e-6,10e-6 box. From the Sub-domain menu...

Is there a formula relating the free resonating frequency of a cantilever to its deflection? Thanks!

Hello, actually, I am looking for some data concerning horizontal cantilevers that bend under the influence of the gravitation force. The cantilever should be rectangle-shaped, with given young-modul, poisson-ratio and of course measures. In addition to that, the deformation of the cantilever...

Right now I'm trying to make a cantilever with the highest efficiency. I'm trying to design several models but I have questions: How can one make one without having to find the best design through numerous times of trail and error? Is there an equation for cantilevers which dictate the...

Hi guys & girls, I have a problem, I am trying to calculate the residual stress as a function of depth of each layer. I am using a Focused Ion Beam system to milling/removal thin layers of material from each layer of this cantilever, & measuring the deflection. I can obtain the average...

I need some help. I writing up a lab report and I am not sure how to define the equtaion i took down in my notes. deflection = (4F/Ebh^3) * L Im not sure if this is the right eqution. If so can some one please tell me what the varibales: E, b, F and h are. Thanks

Hi guys, just wondering if you could help me out? For a standard rectangular cross-section cantilever beam with a concentrated end load how do i work out the top surface stress at a point along the beam? do i just use sigma=My/I where y=half the depth of the beam and M=end load * distance...

I am trying to determine some general cantilever equations. I have an aluminum beam extending out 235 mm (L) from an aluminum block. The beam is 25 mm wide (W) and 3 mm thick (H). A force is applied at a point approx. 200 mm from the block and I am interested at a point 25 mm away from the...

Homework Statement A cantilever beam carriers an end load of 20kN and has an EI value of 40 KNm^2. If the beam is 0.25m long, use intergration to determine the slope at the free end of the beam? Homework Equations I know from a handout I have that the fudamental equation to...

Intuitively, if we have a beam nailed down to a box of some sort on one side and have the other side of the beam stick out (with an object on it), we would expect the beam to bend to an extent. However, when I tried to apply the knowledge of physics that I have, I had a bit of trouble explaining...

Can anybody tell me how to work out the deflection of a cantilever beam with a stepped diameter? I have looked through Roark's Formulas but can't seem to be able to do it The diameter of the beam would vary from 5mm to 3mm and back up to 5mm. I have attached a pic to explain. Thanks for...

Cantilever Help! Hi, I'm trying to do some work on a cantilever beam with UDL and load on the end. Is there anybody who could give me a hand because I am really struggling. Many thanks P

hello all followin my quest to teach myself all about beams etc iv come across this it seems straight forward well, first bit does anyway :) is it basicaly looking at the cross section of the I-section and stating the distance from the base to the middle?? forthe second part do you jus...

Ok I was given this problem: Problem: The deflection d of a cantilever beam of length L is given by the mechanics of materials equation d=PL^3/3EIWhere P is the force on the end of the beam and E is the modulus of elasticity, which has the same dimensions as pressure.Determine the dimensions of...

ok... i need someones help! for a project, a group of us had to build a cantilever, and write a paper. we are at the paper writing stage, and i got shafted with the hard part. which of course i don't know how to do. physics isn't my forte. here is what it says right off of the rubric...

A cantilever beam is loaded by a uniform shear stress T on its upper surface. How to calculate the stress and deflections at the end of the beam?

Hello, I am a PhD student in textiles. I was wondering whether anyone has any experience with cables and stuff. For my PhD, I have implemented a Cosserat model for these one dimensional structures as described by the equations of motion given in this article. Ofcourse one tries to validate their...

Cantilever help!§ heh everyone finishing of some work on cantilevers and how the movement (when attached to strain gages) affects the circuits resistance, i used a wheatsone bridge and i need some hints for help on the right-up... or any results you could send my way would be great, thanks...

I'm an undergrad. student trying to do research. Today was my first day working with grad students and one grad student gave me something to find. We have a cantilever beam made of aluminum nitride (AlN). The only things known about the beam are the dimensions and young's modulus. He wants to...

If i have two cantilever beams with a vertical prop between the free ends as shown in diagram, how do i find the load on the prop? I have the deflections of the beams to be: v (top beam)= (PL^3)/(3EI) v(bottom beam)=(5WL^3)/(48EI)-(PL^3)/(3EI) the prop is of diameter d, and length a...

If two cantilever beams are fixed at Left Hand Side (LHS) and joined to each other by means of a prop at RHS, how do i calculate the downwards vertical deflection of the bottom beam? The solution i need to prove is (5WL^3)/(48EI)-top deflection. However, i always seem to get a 7 where...

If a cantilever beam is subject to forced vibration (from a shaker at fixed end), what will the effect be of placing a mass at a)nodes and b)between nodes? I presume that as there is no displacement from the normal at the nodes, the mass will have little effect, but what about between the...

Is a well studied problem. I am a textiles engineer and am doing some work on modelling the interaction of the yarn with a brush ring (circular brush with hairs slowing the yarn down). You can easily calculate the deformation of a hair caused by a force perpendicular to the curve of the hair in...

Hi, I'm doing a project for my HS physics class. I need to build a cantilever out of craft sticks (I'm using thin bass wood sticks) that needs to be at least 12 inches long. I'm being graded on the efficiency of it by weight (amount of weight it holds on the end divided by the weight of the...

hi guys, got a lil question: I had an experiment to do with two partners and one of 'em lost the data. So they had to redo it, but from the data they supposedly collected, I get the impression the faked the results, badly. The experiment was to bend a ruler by attaching a mass at its end...
