A water main springs a leak and the geyser is estimated to be 20 feet in height. It is also estimated that about 300 gallons per minute is leaking based on flow into gutter. About how big is the hole in the water pipe?
A stockpile of gravel that has a water content of 6% is rained on so that its water content increases to 9%. Compute the difference in the weights of dry gravel in a 10 ton truckload taken from the pile before and after the rain.
use zero through forth order taylor series expansions to predict f(2.5) for f(x) = ln x using a base point at x=1. compute the true percent relative error for each approximation. discuss the meaning of the results.
Determine the strain components strainx, Strainy, and gammaxy, then sketch the deformed shape in the xy orientation, paying particular attention to the sign of the shear deformation.
Also calculate the deflection of the beam to check that it complies with the design limit of L/200. Only variable actions are required for deflection check.
Plot the stress-strain curve and determine the proportional limit, modulus of elasticity (i.e., the slope of the initial part of the stress-strain curve), and yield stress at 0.2% offset. Is the material ductile or brittle
What is your recommendation for the maximum size of coarse aggregate for the following situation?
For Oil (SG=0.86, u=0.025 Ns/m^2) flow of 0.3m^3/s through a round pipe with diameter of 500 mm, determine the Reynolds number. Is the flow laminar or turbulent
The three blocks shown move move with constant velocities. Find the velocity of each block, knowing that the relative velocity of A with respect to C is 300 mm/s upward and that the relative velocity of B with respect to A is 200 mm/s downward.
A U manometer reads 20 cm air as operating fluid and a given manometric fluid. A single branch closed tube reads 35 cm connected to point 1. If P2 = 1.2 ATM calculate the pressure in point 1 and the density of the manometric fluid.
Your engineering consulting firm has been asked to determine the specific weight of an unknown material. You decide to use the concept of buoyancy to figure this out. So you weigh the material in both air and water.
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..
