The weight of the beam pushes straight down on the piers. The beam itself must be strong so that it doesn't bend under its own weight and the added weight of crossing traffic. When a load pushes ...

When a 'beam' experiences a bending moment it will change its shape and internal stresses (forces) will be developed. The photograph illustrates the shape change of elements of a beam in bending. Note ...

The mast of a ship, the pole of a sign post, the frame of a car, the bulkheads in an aircraft, and the plank of a seesaw are among the countless examples of beams. In most cases the bending loads are ...

The principle is simple: laser beams, if they are powerful enough ... To make sure the channel stayed open long enough to bend lightning during a storm, scientists developed a laser able to ...
