Determine the reactions at the supports. Given: w = 250lb/ft a = Determine the reactions at the supports. Given:w = 250lb/fta = 6 ftb = 6 ftc = 6 ft
Three shafts and four gears are used to form a geartrain which will transmit 7.5 kW from the motor at A to a machine tool at F. (Bear- ings for the shafts are omitted from the sketch.) Knowing that the frequency of the motor is 30 Hz
The dimension h is to be determined so that a worker can comfortably slide boxes weighing up to 100lb up and downa frictionless incline. If the worker can apply a 50lb horizontal force to the box
A tiler is removing broken tiles from the roof of a house, and throws a tile with a velocity of 8 m/s at an angle of 20 degrees above horizontal. At the point of release the tile is 5.2 m above the ground surface.
A sample with a measured background level (Bi) of 22 mg/l was spiked with the equivalent of 30 mg/l without appreciably changing the sample volume. The result for the spiked sample (Ai) was 49.2 mg/l. Calculate Pi and determine if it falls with th..
We are digging a hole to build a building. Calculate the energy needed to bring the soil to surface level. Remember the sides of the excavation lie at 45 degrees. Else, the whole would be constantly refilling itself.
Calculate the volume of a cylinder that contains 60 lbm of carbon dioxide at 230°F and 23 psig pressure. Assume atmospheric pressure to be 14.7 psia.^4
water flows through a pipe of diameter 3 inches. If it is desired to use another pipe for the same flow rate such that the velocity head in the second pipe is four times the velocity of the first pipe.determine diameter of pipe
Determine the settlements when a stress of 100 kPa is applied by the building over an area of 10m × 5 m on the soil surface.
a fluid flowing in a pipe 30cm in diameter has a uniform velocity of 4ms. the pressure at the center of the pipe is
The diaphragm is ruptured and fluid fills the entire volume of the vessel. Assume that the fluid is an ideal gas. After you have determined Qsub12, Wsub12, and delta U for the process, calculate the final temperature of the gas.
It is commonly known that there are 16 ounces in 1 lb. Consider a 0.5lbf glass that weighs 1 lbf when filled with 8 ounces of liquid. Determine the liquid density in British gravitational units and in SI units. Also calculate the specific weight in b..
A cylinder of rock with a Poisson's ratio of 0.422 has ano-load length equal to 17.6 cm and a no-load diameter of 6.20cm. Under an axial compressive load the axial strain is foundto be -3.44 mm/m.
