Static of Beam and Internal Force ( Mechanical Engineering )

In summary, the conversation discusses understanding statics of beam, drawing the shear and moment curve, and calculating shear and moment in a beam. The speaker suggests solving for support reactions first and researching examples online. They also provide links to websites for more information on bending, shear stress, and beams.

I am currently in my first year in Mechatronics Major, and now I am trying to understanding about statics of beam. How about draw the shear and moment curve? How about if the force is variation and have graph too.
Just like this for example

V the curve of this like sinus or cosinus for example.
|||||||||||||||||||||| => 4N/m
V V V V V V V V V V V

Shear and moment in a beam depend on loading and support conditions. Solve for the support reactions first. There are numerous examples on the web (do a 'google' search on shear and moment diagrams). The slope of the shear diagram at any point is the loading distribution at that point. The slope of the moment diagram at any point is the shear at that point. It's probably best to look through the voluminous websites for clear examples.
 

Related to Static of Beam and Internal Force ( Mechanical Engineering )

What is the definition of "static of beam" in mechanical engineering?

The statics of a beam refers to the study of the behavior of a beam under external loads, such as forces and moments. It involves analyzing the forces and internal stresses within the beam to ensure that it can support the intended load without failure.

What are the different types of internal forces that can act on a beam?

The three main types of internal forces that act on a beam are tension, compression, and shear. Tension is a pulling or stretching force, compression is a pushing or squeezing force, and shear is a force that causes one part of the beam to slide past another.

What is the difference between a simply supported beam and a cantilever beam?

A simply supported beam is one that is supported on both ends, while a cantilever beam is supported only on one end. Simply supported beams are usually used to span short distances, while cantilever beams are used for longer spans or when a support structure is not available on both ends.

What are the equations used to calculate the internal forces in a beam?

The equations used to calculate the internal forces in a beam are the equations of equilibrium, which state that the sum of all forces and moments acting on a body must equal zero. These equations are used to determine the magnitude and direction of the internal forces at any point along the beam.

How do you determine the maximum bending moment in a beam?

The maximum bending moment in a beam occurs at the point where the shear force changes sign. This point is called the point of inflection or point of contraflexure. The maximum bending moment can be calculated by finding the value of the shear force at this point and multiplying it by the distance from the point to the support.
