Deflection of beams is a fundamental concept in structural engineering that plays a critical role in the design of buildings, ...

This video is an introduction to shear force and bending moment diagrams. What are Shear Forces and Bending Moments? Shear forces and bending moments are resultants which are used to conveniently ...

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." ...

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 ...

"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, ...

There's a microwave power experiment heading to space Saturday (May 16) aboard the Air Force's secretive X-37B spaceplane. Researchers hope it could lead to a new global power source.

A secretive military space plane will soon test the idea of using microwave beams to send solar power to Earth from space. The U.S. Air Force's X-37B space plane is expected to launch into orbit ...
