Deflection: steel or wood

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

AnswerB. 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.
