Thanks for your comments. I had already searched the internet before posting this topic. I didn't get satisfactory results from the searches at that time. After more searches I believe the first question has been answered, courtesy of information from this link here ! But from another...

There are actually several questions. The formula for calculating the "beam angle" of light (emitted from lights bulbs, flashlights etc) is - α = 2 arcCos ( 1 - Lm ÷ ( 2 π Cd )) Where, α = beam angle in degrees Lm = luminous flux (Lumens) Cd = luminous intensity (Candela) The above formula...

Sorry, I didn't realize that you were proposing TWO beams welded together!? My calculation was just for one beam. I'll have another look at your proposal for two beams shortly. The formula you show (5/384 x W/E x L^4/I) for calculating displacement, I believe to be incorrect (a printing...

Wrong Formula? OK. This is what I get using formulae from Machinery's Handbook 27th edition. First, the variables. Steel rectangular hollow beam with external dimensions - 2" wide by 5" high. Internal dimensions (subtracting 0.09" beam wall thickness) - 1.82" wide by 4.82" high. Beam...
