Water from a stationary nozzle strikes a flat plate (directed normal to the plate as shown in the figure). The velocity of the water leaving the nozzle is 15 m/s and the nozzle area is 0.01 m2. After the water strikes the plate, subsequent flow is parallel to the plate.
a. Find the horizontal force that must be provided to the plate by the support.
b. Find the maximum longitudinal normal tensile stress in the support post if it is a hollow square cross section as shown. Model the force due to the water as a point load.
c. Find the maximum transverse shearing stress in a cross section of the post.
A 100 lb force vector F is aligned from A to B. Point A is located at the coordinates (2, 2, 2) and point B at (4,5,6). Calculate the moment of F about the y axis.
A steel shaft with a diameter of 40mm and length of 1.1m transmits 60hp from an electric motor to a compressor. If the allowable shear stress is 50MPa and the allowable angle of twist is 1.5 degrees
the 15,000 kg boxcar A is coasting freely at 1.5 m/s on the horizontal track when it encounters a tank car B having a mass of 12,000 kg and coasting at 0.75 m/s toward it. If the cars meet and couple together
The average rate of water consumption from this tank is 6.25 kL per day, every day. The farmer refills the tank (overnight) every 14 days, using a pump that takes water from a nearby river. The top of the tank is 53m (vertically) above the level o..
You are given the following information about a dry-batchpaving operation. You are going to use one mixer that has a servicerate of 30 serives/hr. The dry-batch trucks you use forbringing concrete to the paver have an arrival rate of 7.5 arrivals/hr...
what is the rate of evapouration of water from a reservoir with air temp at 20c and the surface of reservoir is 3000m2.
A car is traveling along a road at a uniform velocity when at time zero the driver recognizes a hazard. At a moment 0.8 seconds later the driver brakes her vehicle , resulting in her vehicle sliding 90 ft in the same direction
Find the magnitude of the velocity and acceleration for the point having the coordinates (3,4). Specify units in terms of L and T.
