Closed Book Exam. Hand in blue books to KECK LABORATORY by 9AM. ------------------------------------------------ beam is subjected to maximum bending moment of 15 kNm.
a) Calculate the maximum bending stress if the beam profile is IPE 240.
b) Choose an appropriate IPE profile if the maximum allowable normal stress is 170 MPa. 6. A rectangular beam with cross section 120 × 40 mm (upright) is subjected to a bending moment of 20 kNms and an axial pull of 100 kN. Calculate the largest composite normal stress
Design the ramp for the highest design speed (to the nearest 5 mph) without exceeding a minimum D of 8.0. (Assume the PC of the horizontal curve is at station 15+00, and the vertical curve PVIs are at the PC and PT of the horizontal curve). Maximu..
Air (m=28.97kg/kmol) is uniformly heated at steady state as it flows through a cylindrical constant area duct. It enters the channel uniformly at 2.5atm, 300K and 80m/s and exits at 1.5atm.
Your home town is growing so rapidly that another water tower is necessary to meet the needs of the community. Civil and environmental engineers predict that the water tower will need to hold 1.00 X 10.0^6 kilograms of water.
A worker is to paint the walls of a square room 8ft high and 12 ft along each side. what surface area in square meters must she cover?
Route 1 has a free flow travel time of 4 mintutes and travel time increases by 3 minutes and for each additonal 1000 vehicle in flow, and route 2 has a free flow travel time of "b" minutes and travel time increases
As a design engineer you are responsible for all the drawing documentation from your organisation. What are the key aspects of the drawing you need to check before sending it to the construction division
The cost of a 620 ft3/hr process unit is $920,000. From historical cost records, the capacity ratio exponent of a process unit is 0.5. Use the capacity ratios raised to an exponent method to determine the estimated cost of a similar process unit with..
Using the tables in the AISC manual, make a preliminary selection of member size, using a HSS shape. Do not simple state a choice - state your logic step by step, quoting page numbers (AISC) for each step.
What would be the reading on a barometer containing Benzene at 20 degrees Celsius at a time when the atmospheric pressure was equivalent to 12.3 m of water
Discuss the changes in moisture content and the effects of these changes on a piece of dimension lumber from the time the tree is cut, through its processing, and until it has been in service in a building for an entire year
A variable mesh screen produces a linear and axisymmetric velocity profile as indicated below in the air flow through a 2-ft diameter circular cross section duct.
Two identical pool balls of 57.15 mm diameter may move freely on a pool table. Ball B is at rest and ball A has an initial velocity v=v0i. (a) knowing that b=50 mm and e=0.7, determine the velocity of each ball after impact.
