Demand for a particular product is normally distributed with a mean of 100 units and a standard deviation of 20 per period. if there are 120 units in inventory at the beginning of this period:
a) What is the expected cycle service level ( aka type 1 service level)?
b) What is the expected fill rate ( aka type 2 service level)?
The pendulum consists of a 10-kg uniform rod and a 15-kg sphere. If the pendulum is subjected to a torque of M= 50 N*m, and has an angular velocity of 3 rad/sec when theta= 45 degrees, determine the magnitude of the reactive force pin O exerts on the..
A wheel tractor-scraper is operating on a level grade, assuming no power derating is required for equipment conditions, altitude, and temperature.
A tensiometer is used to measure a compacted soil in the field that has a matric suction of 200 kPa under atmospheric conditions. The pore-water pressure measurement in the tensiometer reaches -99 kPa
A turbine located 225 m below the water surface at intake, carries a flow of 3.5 m^3/s. The head loss in the pipeline leading to it is 10 m. Find the power (kW) delivered by the turbine if its efficiency is 92%.
The cycle has a thermal efficiency of 35%, and steam changes from saturated vapor at 300 C during the heat addition process. If the mass flow rate of the steam is 2kg/s, determine the net power (kw) output of this engine.
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.
A 12%, $50,000 bond is offered for sale at $45,000. If the bond interest is payable monthly and the bond matures in 20 years, what nominal effective rates of return per year will the purchaser make on the investment?
A child at a park finds a ball floating in a freshwater pond (temperature 30 degree C). The child swims to the ball and, with an incredible amount of dexterity, balances himself on the ball
The fixture AC is designed with a screw adjustment to regulate the height of the 900 N load supported by the roller at A. The screw bears against a smooth surface at B. Determine the reaction forces at points B and C. Neglect the weight of the fix..
Draw the shear and moment Diagram for a beam that is 10 feet long, supported on the left end by a roler, and the right end by a pin, and has a 1000 lb load placed in the center i.e at 5 feet.
On a specific westbound section opf highway, studies show that the speed density relationship is u=uf *[1-(k/kj)^3.5]. It is known that the capacity is 4200hehicle/hr and the jam density is 210 veh/mile.
Emissions of heat-trapping carbon dioxide (CO2) reached an all-time high of 31.6 gigatons in 2011, a 3.2% increase over 2010. The International Energy Agency said this further reduces the chance that the world can avoid a dangerous rise
