Using A36 steel select the lightest equal leg single angle member to resist a factored (LRFD) tensile load Pu = 167 kips. The member will be connected through one leg with one line of three 3/4-in Ø bolts spaced at 3 in between centers as shown. The edge distances Leh = Lev = 1.5 in. Use LRFD Method Use U from Table D3.1, Case 8. See attached (D3.1 Case 8, Shear Strength of Bolts, Table 1-7 Dimensions of Angles).

Some of these vehicles have electronic identifiers that allow them to enter the park immediately, beginning at 8:00 A.M., without stopping (they are billed remotely). All vehicles without such identifiers stop at a single processing booth, but they wait in line until it opens at 8:10 A.M. Once open, the operator processes vehicles at μ(t) = 8 + 0.5t [where μ(t) is in vehicles per minute and t is in minutes after 8:10 A.M.]. An observer notes that at 8:25 there are exactly 20 vehicles in the queue. What percent of arriving vehicles have electronic identifiers and what is the total delay (from the 8:00 A.M. until the queue clears) for those vehicles without the electronic identifiers (assume D/D/1 queuing)?arrow_forward1.
