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 ...

Pre-stressed concrete is an ideal material for beam bridge construction; the concrete withstands the forces of compression well and the steel rods imbedded within resist the forces of tension.

Scientists have taken a giant leap forward in particle physics by creating an electron beam with five times more peak current than any similar beam ever produced. This major achievement addresses ...
