A bridge having a horizontal top cord is span between tow piers Aand B having an arbitrary height. It is required that apin-connected truss be used, consisting of steel members boltedtogether to steel gusset plates. The end supports are assumed to bea pin at A and a roller at B. A vertical loading of 5 kN isto be supported within the middle 3m of the span. This loadcan be applied in part to several joints on the top cord withinthis region or to a single joint at the middle of the topcord. The force of the wind and the weight ofthe members are to be neglected. Assume themaximum tensile force in each member cannot exceed 4.25 kN; andregardless of the length of the member, the maximum compressiveforce cannot exceed 3.5kN. Design the mosteconomical truss that will support the loading. The members cost $7.50/m and the gusset plates cost $8.00each. Submit your cost analysis for thematerials, along with a scaled drawing of the truss, identifying onthe drawing the tensile and compressive force in eachmember. Also include your calculations of thecomplete force analysis.
What superelevation rate would you recommend for a roadway with a design speed of 100 km/hr and a radius of curvature of 500 m? Assume f = 0.11.
As a consulting engineer you are hired to evaluate the operation and the unit processes within the plant and make recommendations for improvements. You are asked to consider the following units.
The natural ground water table at a site is located at a depth of 2m below the ground water. Laboratory tests reveal that the voidratio of the soil is 0.85 while the grain size corresponding to 10%finer is 0.05 mm.
if the steel tape to be used is only 99.98 under standard conditions and if the temperature is 87 degree farenheit at the time of the measurement, how far away from the existing station mark at 0 + 79.23 will the surveyor have to measure to locate..
A water main springs a leak and the geyser is estimated to be 20 feet in height. It is also estimated that about 300 gallons per minute is leaking based on flow into gutter. About how big is the hole in the water pipe

given that E for the tube material is 70 GN/m2 and the stool legs are 75cm long, how much will each leg shorten under the applied compressive load (take g = 9.8m/s2)
An earthen channel will be excavated into sandy soil for which Vmax = 4.0 ft/sec, n=0.022 and the recommended m=3. The channel will have a bottom slope of 0.0011 and accommodate a design flow of 303 cfs. Design (size) the channel section.
A normally consolidated clay layer in the field has a thickness of 3.2 m with an average effective stress of 70 kN/m^2. A laboratory consolidation test on the clay gave the following results: Pressure (kN/m^2)=100, 200 Void Ratio=0.905, 0.815
