The x-component of a velocity field is ax+b.If the flow is steady, two-dimentional and incompressible; generate an expression for velocity component in the y-direction as a function of x and y.
Replace the given forces by a wrench and determine the coordinates of the intersection of its line of action (the coordinate of point P) with the plate. With a Force Fca=(100i+100j)N coming off of point C
A surveyor measures an angle with two instruments; call them A and B. Both instruments produced unbiased measurements, but the standard deviation of measurements made with instrument A is twice that of B.
The available relay for switching a secondary circuit requires 4 volts and has a coil resistance of 145 ohms. If a voltage divider circuit is used to reduce the voltage to activate the relay, what resistor is needed to create the necessary coil vo..
Estimate the effective friction angle for the sand (assume c' = 0). Calculate the sand's shear strength (τf) on a horizontal plane at depths of the 20 ft and 50 ft.
A 100 gram piece of ice cooled at -20 degrees Celsius is placed in the calorimeter. What is the final temperature of the system, and what mass of ice and water remains
A small truck is to be driven down a 4% grade at 70mi/hr. The coefficient of road adhesion is 0.95, and it is known that the baking efficiency is 80% when the truck is empty and decreases by one percentage point for every 100 lb of cargo added.
A 2000-lb wheel load is to be supported by aggregate over soil with a maximum bearing pressure of 1000 lb/sqft. What depth of aggregate is needed if the angle theta is 40 degrees
A soil sample with a volume of 0.5 m3, dry unit weight = 18.1 kN/m3, water content = 5%, and Specific Gravity of the soil solids = 2.68. Calculate weight of water added to reach 90% saturation (in kilograms)?
You have two wires connected end to end. Wire 1 is copper and wire 2 is made using a special carbon conductor. Wire 1 has a resistance of 0.215 ohms/ft and is 500 ft long. Wire 2 has a resistance of 0.141 ohms/ft and is 700 ft long.
Find the maximum shearing stress and its location in the shaft and the angle of twist of A with respect to C. Let G = 4x10^6 psi for the entire shaft.
The total length of the hose is 65 m with 200-mm diameter. The exit diameter of the nozzle is 100 mm. Take e/D for the hose as 0.0001. What power is needed from the pump on the water
An obstruction is lodged in a 10-ft wide rectangular channel (n = 0.022) that has a botom slope of 0.005. The depth of the channel just upstream of the obstruction is 5.0 ft. If the flow rate is 325 cfs, what is the channel and flow classification
