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 Answer B. L/360 or span in inches divided by 360.

However, even when the equation may be available in in-exam reference, selection of the appropriate equation requires correct identification.

Facility parking

A new office complex is being planned, which is required to include 162 parking spaces. In addition to the parking spaces, allow for related driveways and walkways to estimate the area of the parking lot that would satisfy this number of spaces. A. 1.0 acres B. 1.5 acres C. 1.75 acres D. 2.0 acres Answer B. 1.5 acres. Multiply the required parking spaces by 400 sf per car (1 acre = 43,560 sf). If walkways are not required, use 300 sf per car. ARE 4.0 exam prep: SPD
