Is light beam visible in milk?
When a beam of light is passed through milk solution, then the beam of light get scattered through the milk solution and the path of light becomes visible in the milk solution because milk solution is the COLLOIDAL solution. ( in colloidal solution the size of particles is big enough to scatter a light.)

Which type of beam is the strongest?
I-Beam. . . . is the quintessential beam profile. The design is super strong in the vertical direction, yet has a uniform and equal response to other forces. It has the best strength to weight ratio (vertical) making it a great DIY beam profile for Cranes, and for the main beams of big and/or long trailers.
