Mr. Joshua Lacey set the track record in a meet at LSU. For this
achievement, he gets to choose
between a $250 cash prize paid immediately or $30 per year for 10
years. He already has
enough money for now so he decided on the 10 annual installments.
However, he is considering
the following two investment options:
a. Save the winnings for the first 3 years and then spend every
cent of the winnings in the
remaining 7 years that is collected.
b. Spend everything for the first 3 years then save the remaining 7
years of winnings collected.
i). Draw the cash flow diagram for each option (a) and (b).
ii). Also, if Bank plus is advertising that they can give him a
savings ROR of 11% per year, how much
would each option (a) and (b) payout after the installments end?

Suppose you observed vehicle arrival flows in a single approach for two consecutive cycles at a signalized intersection. The signal has a 60 sec. cycle time with a 30 sec. green interval and a 30 sec. red interval (ignore yellow interval). The arrival rates are assumed to be constant in both cycles. The arrival rate was 720 veh/hour. Assume that the vehicles in the queue formed on red pass through the intersection during the subsequent green interval at the saturation flow rate of 1800 veh/hour immediately after the start of the green interval.
(a) Draw the queuing diagram for the approach during the two cycles
(b) Calculate the total uniform delay per cycle.
(c) Calculate the average delay per vehicle.
(d) Calculate the maximum queue length (i.e. maximum number of vehicles in the queue).

Answer the following questions from Civil Engineering Licensure Examination
a. CE Board May 2007
A 300 mm concrete wall supports a dead load of 300 KN/m and a live
load 0f 220 KN. The allowable
bearing pressure is 240 KN/m2 and the level of the footing is 1.2 m
below the ground surface. Assume
concrete weighs 24 KN/m3 and that of soil is 16 KN/m3, fc’ = 28
Mpa, fy =248 Mpa. Use 28 mmθ
reinforcing bars. Thickness of footing = 600 mm, steel covering 100
mm. Determine the spacing of bars
at critical section.
b. CE Board May 2012
A 450 mm square interior column carries a dead load of 825 KN and a
live load of 668 KN. A
rectangular footing is required to carry the column loads such that
the length of the long side must be
equal to twice the width of the short side. Assume base of footing
is 1.5 m below the ground surface.
Allowable bearing pressure of soil is 15.74 KN/m3 and that of
concrete is 23.5 KN/m3. Use normal
weight concrete. Thickness of footing is 0.60 m. Determine the
steel requirements in the short and
long direction
