Web14 de abr. de 2024 · The far-field spot profiles of the Bessel–Gaussian beam were measured by using lasers (TSL-550-CL-Band, Santec, Japan) and infrared camera (Bobcat 640 GigE, Xenics, Belgium). Web1 de mai. de 2006 · Typical laser-beam profiles include Gaussian; tophat (flat-top), either circular or rectangular; and line, with a Gaussian profile across the line and tophat along the line. The de facto industry-standard definition of beamwidth, which relates to a Gaussian beam shape, is the width at the 1/e 2 intensity level (13.5% of the peak intensity).

WebTimber beams are widely used in home construction. When the load (measured in pounds) per unit length has a constant value over part of a beam, the load is said to be uniformly distributed over that part of the beam. Consider a cantilever beam with a uniformly distributed load between 110 and 155 pounds per linear foot. a.
