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 ...

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 ...

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." ...

"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.

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, ...
