Compute azimuths of all lines for aclosed traverse ABCDEFGHA that has the following balanced angles tothe right, using Bearing AB = N56º18'42"W.
Balanced angles: HAB = 78º26'59",ABC = 153º07'38",BCD = 203º58'37",CDE = 83º52'50",DEF = 98º11'03",EFG = 218º24'21",FGH = 94º24'52",GHA = 149º33'40".
A 4000-m 3 /day conventional activated sludge plant has an influent with a BOD5 of 190 mg/L and SS of 225 mg/L. What population would this plant serve?
The road is in good condition and is initially dry, but it becomes wet 160 ft before the stalled car (and stays wet until the car is reached). What is the minimum distance from the stalled car at which the driver could apply the brakes and still s..
A steel I beam is supported by a pin at point A and a rocker at B, and a cable applies a 2000lb force. The beam is uniform and weighs 26 lb/ft. Determine the support reactions.
The maximum gage pressure is known to be 8MPa in a spherical steel pressure vessel having a 250mm diameter and a 6mm wall thickness. Knowing that the ultimate stress in the steel used is (sigma u)= 400MPa, determine the factor of safety with respe..
A building frame is made with a 10" square steel box shape that has an area of 15 in^2 and a moment of inertia I =225 in^4. The frame consists of pinned supports at points A and F and an internal pin at point D.
Find max pressure at bottom of gate (psi) 2. Total horizontal force on gate 3. moment about the bottom of the gate
The true bearing of the line a-b is S 88*50' W, the magnetic bearing of the line d-c is N 89*45' E. What is the magnetic declination
An equal-tangent crest curve connects a +2% initial grade with a -1% final grade, and is designed for 55 mi/h. The station of the PVI is 233 + 40 with elevation 1203 ft.
For a total floor load of 75 psf on 2x floor framing at 24 o.c., determine an appropriate plywood thickness and span rating assuming panels with edge support and panels oriented perpendicular to the framing. Specify the minimum fasterners and spac..
The pressure inside the cylinder is 50 atm and temperature is 298o K. Provide your engineering judgement (with calculations) to justify or not justify the shipment of the cylinder.
A rectangular channel is to carry 200 cfs. The mean velocity must be greater than 2.5 fps. The channel bottom width should be about twice the channel depth. Find the channel cross section and the required channel slope.
Knowing that the magnitude of P is 35 N, determine by trigonometry (a) the required angle a if the resultant R of the two forces applied to the support is to be horizontal, (b) the corresponding magnitude of R.
