The post is embedded into a concrete footing so that it is fixed supported. If the reaction of the concrete on the post can be approximated by the distributed loading, determine the intensity of w1 and w2 so that the resultant force and couple moment on the post due to the loadings are both zero.
Colette Lake has a surface area of 103 ha and a mean depth of 8 m. The pH of the water is 7.6. The lake receives surface water from a lake upstream, rainfall, and diffuse groundwater input. Atmospheric inorganic N deposition is insignificant.
a wall 8 ft high is 3/3/8 ft. from a house. find the shortest ladder which will reach from the ground house when leaning to the wall.
Design a simply supported one-way reinforced concrete floor slab to span 10 ft and carry a service live load of 175 psf and a service dead load of 25 psf. Use fc' = 3000 psi and fy = 60,000 psi.
Each week 85 trucks bring a total of 2,180 metric tons of municipal solid waste (MSW) to the landfill. Each truck averages two loads per day. Each truck has a capacity of 4.5 metric tons and they operate 5 days/week.
A bag of potatoes is sitting on the chair. The force exerted by the potatoes on the frame at one side of the chair is equivalent to horizontal and vertical forces of 24 N and 84 N, respectively, at E and a force of 28 N perpendicular to member BH ..
The velocity of the bed is limited to a maximum value of 150mm/s to the right and 300mm/s to the left; the acceleration is successively equal to 150mm/s^2 to the right, zero 150 mm/s^2 to the left, zero, etc.
The slope of the channel is .15% and the mannings roughness coefficient is .038. estimate the depth 100m upstream of a section where the flow depth is 2.2m using the standard step method. Approximate how far upstream of this section would you exp..
a simple random sample of 20 items from a normal population resulted in a sample mean of 17.25 and a sample standard devation of 3.3 a. develop a 90% confidence interval for the population mean. b. develop a 95% confidence interval for the populatio..
