A pendulum consists of two 3.2-kg concentrated masses positioned as shown on a light but rigid bar. The pendulum is swinging through the vertical position with a clockwise angular velocity ω = 6 red/s when a 50-g bullet traveling with velocity υ = 300 m/s in the direction shown strikes the lower mass and becomes embedded in it. Calculate the angular velocity ω which the pendulum has immediately after impact and find the maximum angular deflection θ of the pendulum
House chilled water is available for cooling coming from 6-in dia. chilled water line carrying chilled water at approximate constant 40 degree F temperature. Chilled water pressure in the 6-inch line is 110psig.
The bar is fixed at B (length=2a) with a pin support at A (length L=0). Additionally, at A is a torsion spring (spring constant Ca = EI/a) and an extension spring is attached at B (spring constant Cb = EI/(a^3)).
Prepare a capstone report for designing of steel building using AISC 14 edition manual.
the inclined leg differential manometer as shown in figure 1 below shows a reading along the inclined leg mercury
The city of Lancaster's water distribution system has 3 wells for water supply. There are 10 pumps at these wells. It is estimated that a pumping rate of 10,000 gallons per minute is needed to satisfy the city's total water demand.
The local engineer concludes that, since the oil must have been destroyed by the soil microorganisms at a rate of 20 mg/kg each year, in one more year the site will be free of all contamination. a. Is this a good assumption
Calculate the vapor pressure, air pressure, relative humidity, and air density at elevation 1500 m if air temperature is 25 degrees C and dew point temperature is 20 degrees C and the lapse rate is 9 degrees C/km
The pavement structure consists of 160 mm of hot-mix asphalt (HMA), 150 mm of granular base and 450 mm of subbase placed over silty clay subgrade. The pavement is 20 years old and its current PCI is 50.
How high (m) a column of ethyl alcohol would be required to give the same pressure as 700 mm Hg
on a summer day when the wind speed in 3 ms a tank truck loaded with liquid chlorine is involved in an accident that
Design a lined trapezoidal channel to carry 20 m^3/sec on a longitudinal sloe of 0.0015. The lining of the channel is to be float-finished concrete (n=0.015). Consider (a) the best hydraulic section and (b) the section with side slopes 1.5:1 (H:V)
When theta=0 degrees , the assembly is held at rest, and the torsional spring is untwisted. If the assembly is released and falls downward, determne the angular velocity at the instint theta=90.
