Why does the earth have Leap years that include 29 February? calculate the sum of the series [infinity] an n = 1 whose partial sums are given. sn = 7 5(0.8)n Design a beam for a 24-ft simple span to support the working uniform loads ofWD = 1.25 k/ft (includes beam self-weight) and w = 3.0 k/ft. The maximum per-missible total load deflection under working loads is 1/360 of the span. Use 50 ksisteel and consider moment, shear, and deflection. The beam is to be braced laterallyat its ends and midspan only. Determine Ch. (Ans.
