1.An open rectangular tank 1m wide and 3m long contains water to a depth of 1m. If the height of the tank sides is 1.5m, what is the maximum horizontal acceleration (along the axis of the tank) than can develop before the water spills?
2.A 0.5m diameter pipe is filled with a fluid with a specific gravity of 1.5. Determine the force at the circular endcap and its location relative to the bottom of the pipe. If there is a hinge at the bottom, what external force would need to be applied to the top to prevent rotation
A train of total mass equal to 500 Megagrams starts from rest and accelerates uniformly to a speed of 90 km/h in 50 s. After reaching this speed, the train travels with a constant velocity.
The microstructure of an iron-carbon alloy consistsof proeutectoid ferrite and pearlite; the mass fractions of thesetwo microconstituents are 0.174 and 0.826, respectively. Determinethe concentration of carbon in this alloy.
Given a reinforced concrete beam made with 3000psi concrete and grade 40 steel. The effective width is 12 inches, the beam depth is 24 inches and the reinforcement is 4#7 bars centered 2-1/2 inches
The pump graphs are given to us, and I'm asked to determine possible lengths and diameters of the pipe to meet two requirments. The system can have multiple outputs in order to satisfy the needs, but they must be occuring at the same time.
a cylinder has 500 cm3 of water. after a mass of 100 grams of sand is poured into the cylinder and all air bubbles are removoed by a vacuum pump, the water level rises to 537.5 cm3. Dteremine the specific gravity on the sand
A Pelton wheel, located at an elevation of 200.0 m, is used to extract power from a reservoir at an elevation of 800 m. A penstock 1500 m long and 0.8 m in diameter connects the reservoir with the nozzle of the Pelton wheel.
What is the minimum distance from the stalled car at which the driver could apply the brakes and still stop before hitting it? Assume coefficient of rolling resistance of 0.013.
A larger-diameter pipeline will cost $2.1 million installed, but its operating cost will be only $8000 per month. Which pipe size is more economical at an interest rate of 1% per month on the basis of an annual worth analysis
What is the minimum required length L of the rod so that the cross section at one end can be rotated 90 degree with respect to other end without exceeding the allowable shear stress of 300 MPa
The faster you try to open a screen door, the more resistance you encounter. When the door is released, the length of the closer decreases linearly with time until it returns to its intial length. Do any of the three viscoelastic models
Soil has been compacted in an earth dam to a bulk density of 2.2 Mg/m3 and a water content of 9.5%. The value of Gs is 2.6. Would it be possible to compact the above soil at a water content of 13.5% to a dry density of 2.00 Mg/m3
A rectangular channel carries a discharge of 2.00 m3/sec per meter of channel width over a weir crest that is 1.4 m in height. The energy grade line upstream of the weir measure 2.7 m above the channel bottom
