Figure Q1 shows a double-inclined plane supporting two blocks M1 and M2 which have masses 12 kg and 70 kg respectively. The system is released from rest in the position shown and the kinetic coefficient of friction between block M2 and the rough plane is ?? = 0.4.
i) Compute the tension and acceleration of the blocks.
ii) Using impulse-momentum method, determine the time taken when M2
reaches a speed of 2 m/s.

1)The stress on the circular footing of 6 m diameter due to column load is 200 kPa at the level of the footing i.e., z = 0 m. Calculate the vertical stress at a depth of 2 m, 4 m and 6 m below the central line of the footing and at edge of the footing. Also, draw the pressure bulb for 10% intensity of the applied in conventional graph sheet .
2)There are two borrowing areas ‘A’ and ‘B’ which have soils with void ratios of 0.8 and 0.7 respectively. The inplace water content is 20% and 15% respectively. The fill at the end of the construction will have a total volume of 10,000 m3, bulk density of 2000 kg/m3 and a placement water content of 22%. Determine the volume of soil required to be excavated from both areas. Assume that the specific gravity of the soils at site ‘A’ and site ‘B’ is 2.65 If the cost of excavation of soil and its transportation from the borrow area to the construction site is Rs 200 per every 100 m3 of soil for Area A and Rs 220 per every 100 m3 of soil for area B, which of the borrow area is more economical and justify your answer with detailed calculations

a)A route within an urban setting has three signalized
intersections in series and at maximum intervals of 50m from one
intersection to the next. During peak periods, there is backflow of
traffic from one intersection to the previous. As a Traffic
Engineer, what cost effective measure will you propose to alleviate
this problem and how will you achieve it? It should be noted that
physical improvements such as relocation of intersection, lane
widening, channelization, etc. cannot be considered as
options.
b) Most of the traffic signal systems used in Ghana are
pre-timed signals. There are instances where phases with high
traffic volumes have green times lower than phases with low traffic
volumes. What could account for this signal timing deficiency and
what can be done to rectify it? (AN,5)

1. Discuss which specific sector of crucial infrastructure you think is least critical (example: chemical, commercial, communication, dams, emergency services, energy, food & agriculture, healthcare, IT, nuclear reactors, transportation, waster & waste?)
2. Discuss what sectors you think to be present within your neighborhood & provide examples.
3. Why do you think that Sector-Specific Plans should be confidential or unclassified, & offer example recommendations
4. Do you think there is other critical infrastructures that belongs in the Sector-Specific Plans?
