Problem 1. A single-storey factory is composed of a number of steel truss structures, as shown in the following figure. For all bars, area A=1000 mm2, E=200 GPa.
The maximum vertical load and horizontal load have been identified and shown in the figure. Under this loading condition, you are asked to determine the horizontal deflection of joint C.
Problem 2. You are asked to analyse a typical beam in "CADET" building, which is a continuous beam with three column supports. By idealising its supports, the beam is shown in the following figure. A is a fixed support; B and C are roller supports. EI is constant.
The maximum vertical load on each span has been identified and shown in the figure. Use the Force Method to compute all the support reactions for this beam.
The bond has a maturity date of 10 years from now. How much the person must sell the bond for 6 years from now in order to make a rate of return of 10% per year, compounded semiannually is closest.
A 40 oF breeze of 10 miles per hour blows over the top of a round open-top water cooling tank which has a bulk temperature of 100 oF. What is the rate of energy in kW that enters into the air
If the fracture were planar in shape, having an average opening of 2 mm, what would the new value of Hc be?
Knowing that the tension is 120 lb in AB and 40 lb in AD, determine graphically the magnitude and direction of the resultant of the forces exerted by the stays at A
Wastewater flow of 2000 m3/day containing 120g/L of salt. Discharge into a river with a flow of 34,000 m3/day and a salt concentration of 50 mg/l. The agency wants to maintain the salt level to no greater than 250 mg/L downstream of the discharge.
a 200ft tape is hung in catenary. It is supported at the 80ft mark the tension is 20lbf and the weight of the tape is 3 lbf 5 0z. The measured distance is 187.01 what it the distance after adjusting for sag
Which of the following is true for a thermistor with a negative temperature characteristic A) Decreasing temperature produces decreasing resistance in the thermistor. B) Increasing temperature produces decreasing resistance in the thermistor.
Determine the cycle time for a single engine scraper rated at 21 cy heaped that is used to haul material from a pit to a fill 900 ft away under severe conditions.
determine the maximum negative moment in each span and maximum negative moment at each support. remember that live loads shall be placed so as to cause the greatest effect. specify the method that you used to determine the moments.
Restrictions in landing slots at Heathrow airport in London allowed the purchase of five landing/takeoff slots, one per weekday (Monday through Friday). The carrier does not intend to offer weekend service.
In a study it was found that 39% of the bacteria died within 9 hoursand 67% died within 20 hours. If the rate of andwer proportional to the number remaining, how long would it take to obtain a 99.9% reduction in the bacteria
