a piston moves a 25kg hammerhead vertically down 1m from rest to a velocity of 50m/s in a stamping machine. what is the total change in energy of the hammerhead?
Two 52 kN loads are maintained 2.5 m apart as they are moved slowly across beam AB. Write a computer program to calculate the deflection at the midpoint C of the beam for values of x from 0 to 9 m, using .5 m increments.
an increment of vertical stress of 150kpa compress the sample to a void ratio of1.43. what is the over consolidation ratio of the soil at the unloaded condition.
Suzanne is a recent chemical engineering graduate who has been offered a 5-year contract at a remote location. She has been offered two choices. The first is a fixed salary of $75,000 per year.
A major relining of the combustion vessel will occur during the fifth year at a cost of $30,000. If the interest rate is 15% per year, what is the lump-sum equivalent cost of this project at the present time
In that season, what are the hydraulic radius of the river, its mean velocity and volumetric discharge?
Given that the max shear strength of the the concrete shore is 10 kPa and the engineer requires a F.S. of 2.5, find the required are of concrete for the thrust block.
The suppliers says it would prefer to sell the company a 65% NaOH solution and the company says the water content is immaterial as long as the equivalent costs are the same including freight.
If the energy loss in the contraction is equal to \(V_1^{2}/2g\) where V1 is the average velocity upstream of the contraction, what is the depth of flow in the constriction. A lined rectangular concrete drainage channel is 10m wide and carries a..
a 60 -m- long steel wire must not strech more than 48mm when the tension in the wire is 6 kn. determine the corresponding value of the normal stress.
The drawdown in another observation well 60 m from the pumping well is 1.1 m. Calculate (a) the hydraulic conductivity of the aquifer, (b) the expected drawdown in the pumping well,
Water is flowing from a higher to a lower reservoir through a 24-inch pipe that has a Darcy friction factor of 0.02. The local loss coefficients for the bends, entrances, and exits sum to 3.5.
What is the elongation of a rectangular bar (cross section 2 inch * 2 inch length 4 ft) When it is subjected to an axial load of 80,000 lbs. Assume the material of the bar has the following properties G = 7,700 KSI, V =0.30
