A cantilever is a rigid structural element that extends horizontally and is supported at only one end. Typically it extends from a flat vertical surface such as a wall, to which it must be firmly attached. Like other structural elements, a cantilever can be formed as a beam, plate, truss, or slab.
When subjected to a structural load at its far, unsupported end, the cantilever carries the load to the support where it applies a shear stress and a bending moment.Cantilever construction allows overhanging structures without additional support.

I want to build this safely, so I am putting this out here for expert advice. My choice for the shape for the aluminum cantilever is angle, T, square tubing or round. The foam is 2” thick, so I’d like to keep the supports at 2” in width and height. I need to...
Not much to add since the question is fairly simple, but again I'm wondering if applying tension at the free end of a cantilever beam affects the deflection it would have if only its self weight is considered. Intuitively, tension should tend to straighten the beam, and if it does, how to...
Homework Statement
i) Determine the slope of the beam 1m from the wall.
ii) Calculate the deflection at the free end of the beam.
Homework Equations
Macauly's method of deflection: M = -RX + W[X-a]
Integrate once for slope
Integrate twice for deflection

I'm doing an experiment measuring the relationship between length of a cantilever beam and period of oscillation when I twang it on one end, but I can't seem to understand the equation. The equation for measuring frequency is given here:https://www.hindawi.com/journals/amse/2013/329530/
but I...
I am trying to derive the strain at the base of a cantilever beam with a known deflection. I know the bending stress is equal to Mc/I, so the strain is Mc/IE, where c is the distance from the neutral axis. For a point load ,P, the strain would then be PL/IE. Since the deflection is known I...
Hello,
i was looking for ways i can reduce the deflection in the cantilever beam whose one end is fixed and load is applied at the free end.
Few i thought of was,
1- Reducing the length of the beam
2- Increasing the modulus of elasticity of the beam
3- ??
4- ...
Good Day, I am looking for mathematical modelling of Joule heating of a simple cantilever beam . Can anybody provide me good source of relevant material.
Thanks in advance.
Attached is my ANSYS model of a spring made using cantilever beams. In playing around with with different dimensions, I noticed that the longer I made the connecting section (dirty green section) the less of a total deflection there was. Could someone explain to me why this is?
The overall goal...
I have a project for a class and our goal is to design a beam using 1018 steel to achieve a certain deflection under one load and not fail under an even larger load.
The design I have come up with is very similar to a cantilever beam, but is has a variable cross section. I have used the...
Hi there!
Im trying to do an analysis in Abaqus of a cantilever pipe, with a tip mass at the free end, that is decelerating to a stop at 10 m/s2 from 10m/s, causing it to vibrate. To validate my results im doing some handcalcs. I have done a static analysis and calculated the maximum deflection...
Homework Statement
The beam ABC is1000LBs and its center of mass is given as 6.5ft to right of B. B is a pin joint. A & D are frictionless rollers. Find tension in cable.
Homework Equations
Call the tension in the cable T.
Trig shows us that the left-hand triangle is 45 degrees at ABD and...
Hi,
I am designing a concrete roof slab that span across 12m long and 9m width for my living area. The support columns are placed in each 4 corners and they are 300mm x 300mm size. The concrete slab roof is cantilevered out by 1.8m on 3 sides (not all 4 sides) with the thickness of 150mm.
At the...
Hello,
I am an electrical engineering student and I was hoping some body here could help me out with a cantilever question.
I want to model a vibrating cantilever with a mass at the end. I am doing this for a project where I wanted to model a Wurlitzer 200 Electric Piano. The way they produce...
Problem:
I do not know how to approach this problem. For a beam which has two reactions, the shear stress is equivalent to the reaction.
I suppose that the stress is calculated using moment some how. But how?
For seeing if the beam is allowable stress design compliant, you can use the...
