A fixed-ended 410UB53 beam spanning6000 mm supports two imposed concentrated forces (live loads) PQ at the third points and a uniformly distributed servicedead load (including the self-weight of the beam) of 10 kN/m, all of which are appliedto the top flange. The beam is fully restrained at both ends but is unbraced along its span. Determine the maximum magnitude of PQ that satisfies the ultimate strength limit state for flexural strength (i.e. do not check shear, bearing, deflection etc). To obtain the bending moment diagram, use standardresults from the Steel Designers' Manual or a similar reference.
The local engineer concludes that, since the oil must have been destroyed by the soil microorganisms at a rate of 20 mg/kg each year, in one more year the site will be free of all contamination. a. Is this a good assumption
A rectangular gate 6 ft tall and 5 ft wide in the side of an open tank is held in place by the force F as indicated in the figure. The weight of the gate is negligible, and the hinge at O is frictionless.
Use microsoft excel functions to find the net present worth of the project, and the internal rate of return,and the annual worth of the project?
A fully loaded, ocean going container ship is just stable about its longitudinal axis (roll). The ship has a total weight of 155,000 tons, length = 1,600 feet and a beam = 150 feet (assume that it is the shape of a rectangular box). Calculate the ..
A toothpaste factory situated on a large river disposes of a waste water containing villiamite (NaF) to the river on a continuous basis. The minimum flow in the river is 210 m3/s, and the discharge rate from the treatment plant is 12.5 m3/s.
It was observed that the truck traveled a distance of 120 ft after the brake was engaged before coming to a complete stop. If instead the driver brings the truck to a velocity of 90 mph and completely engages the brake
If a single deposit of $15,000 is invested at 2.75% yearly interest, what equal year-end withdrawls can be made each year for 10 years, leaving nothing in the fund after the 10th withdrawl
Determine the value and location from point D of the maximum internal bending moment and shear force for the member. Take x = 2 ft. Be sure to draw complete free body diagram(s) for full credit.
If the front edge of a contaminant plume is perfectly straight, how long would it take to travel to Well 1 after first arriving (simultaneously) at Wells 2 and 3, assuming that the contaminant plume travels only half as fast as the groundwater flo..
A wastewater treatment plant has a flow of 35,000 m3/day. Calculate the mass of sludge wasted each day (QwXw, expressed in kg/day) for an activated-sludge system operated at a solids retention time (SRT) of 5 days
Why is the ‘time value of money' important for the evaluation of engineering projects? Provide at least one practical example to support your view (max 2 pages).
A truck is designed to measure concrete roughness. During a typical test the driver will bring the vehicle to a constant test velocity, v, and then suddenly lock the brakes bringing the vehicle to a complete stop.
