Formula
δ = PL³/(48EI)
About this calculator
The Deflexão Carga Pontual calculator calculates the deflection of a beam under the action of a point load.
This calculator uses the formula δ = PL³/(48EI), where δ is the deflection, P is the load, L is the length of the beam, E is the modulus of elasticity and I is the moment of inertia of the beam's cross-sectional area.
Deflection is a fundamental concept in Mechanical Engineering, as it helps understand how structures react to applied loads. Use this calculator when you need to calculate the deflection of a beam under the action of a point load, such as in civil or mechanical engineering projects.
Remember that this calculator assumes the applied load is a point load, i.e. a concentrated load at a single point. If the load is distributed, you will need to use another formula or calculator.
Frequently asked questions
What is deflection?
Deflection is the lateral displacement of a beam or structure under the action of an applied load. It is an important concept in Mechanical Engineering and is necessary to calculate deflection to ensure the safety and stability of structures.
When should I use this calculator?
Use this calculator when you need to calculate the deflection of a beam under the action of a point load, such as in civil or mechanical engineering projects.
What is moment of inertia?
The moment of inertia (I) is a measure of a beam or structure's resistance to deformations or flexions. It is calculated based on the geometry and material of the beam or structure.
Why is deflection important in Mechanical Engineering?
Deflection is fundamental to ensure the safety and stability of structures. If deflection is excessive, the structure may collapse or suffer irreparable damage.
What is a point load?
A point load is a concentrated load at a single point. It is common in civil or mechanical engineering projects, such as bridges, buildings or machines.
