Q1) Design a concrete mixture proportions which will be used for
offshore concrete platform. Norway is a world leader on offshore
concrete platforms with 1a of the world’s 30 larger offshore
concrete structures located on the Norwegian continental shelf. The
first of these platforms where the Ekofisk Tank installed in 1974
and the last was Troll gravity based structure installed in 1996.
The Sakhalin project is located in a harsh and artic environment
where concrete structures have proven excellent characteristics
with a minimum of maintenance. 80 mm slump value is required for
the Sakhalin project. 28-days concrete characteristic strength is
2b MPa. It is required that no more than 1 test result in 100 will
fall below the specified strength. The fine aggregate has a
fineness modulus of 2.60 and Zone 3. For Coarse Aggregate
(Uncrushed): SSD Bulk Specific Gravity: 2.65, Absorption Capacity:
2.b %, Total Moisture: 1.c % and Dry Rodded Unit Weight: 1345 kg/m3. For
Fine Aggregate (Uncrushed): SSD Bulk Specific Gravity: 2.70, Total
Moisture: 3.d % and Free Moisture: 2 %. Cement: Portland Composite
Cement, Specific Gravity: 2.97. For 0.e5 m3 of concrete, binder
amount is calculated as 120 kg (Use ACI Method of Mix
Design)

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).
