Commercial trucks begin to arrive at a seaport entry plaza at 7:50 A.M., at the rate of λ(t) = 6.3 – 0.25t[λ(t) is in veh/min and t is in minutes]. The plaza opens at 8:00 A.M. For the first 10 minutes, one processing booth is open. After the first 10 minutes until the queue clears, two processing booths are open. Each booth processes trucks at a uniform rate of two per minute. What is the average delay per vehicle, the maximum queue length, and the average queue length?
The floor system of a gymnasium consists of a 130-mm-thick concrete slab resting on
four steel beams (A = 9100 mm²) that, in turn, are supported by two steel girders (A =
25600 mm²), as shown in Fig. 2.3. Determine the dead loads acting on beam BF and
girder AD.

Trucks begin to arrive at a truck weigh station (with a single scale) at 6:00 A.M. at a deterministic but time-varying rate of λ(t) = 4.3 − 0.22t [λ(t) is in veh/min and t is in minutes]. The departure rate is a constant 2 veh/min (time to weigh a truck is 30 seconds). When will the queue that forms be cleared, what will be the total delay, and what will be the maximum queue length?

Situation A truss structure is an assembly of straight structural members that form triangular panels. The assembly of triangular panels makes the truss establish a rigid configuration. In a truss structure, connections are theoretically assumed to act as smooth pin; therefore, it does not resist any moment or bending. Due to this magnificent behavior, truss members only resist axial forces in the design phase that could either be compressive or tensile.
