The 1.5m2 pub sign hanging outside The Drunken Engineer, weighs 200N and is hinged along its top edge. Determine the deflection in degrees for horizontal wind speed of 10m/s and what is the magnitude of the force required at the bottom of the sign to prevent the sign from deflecting?
Take the density of air as 1.2 kg/m3. The drag coefficient for the sign can beassumed equal to 1.9 and independent of the Reynolds number.
You are given a mohrs circle with 10 kPa (assume positve since geotech question) in compression for sigmaz and 2 kPa (+ counterclockwise) force for shear z. This force lies on a plane 15 degrees CW.
A discharge of 2,200 ft^3/sec flows in a trapezoidal channel at a normal depth of 8.0 ft. The channel has a slope of 0.01, a 12-ft bottom width, and side slopes of 1:1 (H:V). Determine the manning coefficient of channel roughness
Working a problem where there are two one-story buildings of different heights next to each other. Earthquake imparts a base motion z(t) that is a cosine function. I'm given a shape function for a column of height L when deriving the EOM for each ..
the structure has a curved face being part of a circle with radius R = 32M. The dam holds water to a height = 28 m. Claculate the magnitude and direction of the resultant force per metre length of the dam wall
how many cubic feet of seawater, density 60 lb/ft^3, must be processed to recover 1 ton of magnesium, 1,272 ppm?
A large rock became visible to a driver at a distance of 175 ft. Assuming a perception-reaction time of 0.8s, an initial speed of 42 mph, a coefficient of friction equal to 0.5, and a level roadway, calculate the speed at impact.
Two activated sludge aeration tanks in Podunk, MO are operated in series. Each tank has the follwing dimensions: 7.0 m wide x 28.0 m long x 3.5 m effective liquid depth.
Dust is removed from the airstream of a municipal incinerator by four dust collectors operating in parallel, each handling 1/4 of the total airflow of 200 m3/min. The airstream contains 10 g/m3 of suspended solids.
