This video is an introduction to shear force and bending moment diagrams. What are Shear Forces and Bending Moments? Shear ...

Stresses in beams are one of the most fundamental concepts in structural engineering, directly impacting the safety and ...

Researchers at Singapore’s Agency for Science, Technology and Research (A*STAR) have now proven the theory behind the concept of a Bessel beam-based "tractor beam." ...

Although the forces are not very large, such tractor beams do have real applications, says Wang. "These beams are not very likely to pull a human or a car, ...

"The forces involved with this tractor beam are really huge compared to what had been seen before," says study coauthor Gabriel Spalding, a physicist at Illinois Wesleyan University in Bloomington.

For this exercise, I have taken the centre of gravity (C of G) of the beam to be at the geometric centre of the beam and the two equal length suspension slings to be at 30° to the vertical, attached ...

A mechanical neural network composed of beams, motors and sensors can learn to carry out several different tasks, just like its software equivalent, and could lead to aircraft wings that morph ...
