For EITHER steel or wood beams, a question that asks for the allowable deflection limit (maximum) for live loads only requires which of the following equations? A. L/240 B. L/360 C. ∆ = 5wl⁴ / 384EI D. ∆ = 5Wl³ / 384EI Answer B. L/360 or span in inches divided by 360. ARE 4.0 exam prep: SS Note on calculations: From posted discussions on AREforum , memorization of most equations is not advised. However, even when the equation may be available in in-exam reference, selection of the appropriate equation requires correct identification.
Great site.
ReplyDeleteHowever when i hover over some answers i get a black bar with no answer and sometimes i get a partial answer.
how do i change this?
Maybe check that you have an updated browser. I know some older IE versions like IE 6 don't properly display the feature (FYI - it's a 'tooltip' made with CSS3 stylesheet language). Otherwise Firefox, Safari, Chrome should work.
