The torsional assembly shown in Figure consists of a solid bronze (GB= 45 GPa)shaftCD and hollow aluminium alloy(GA=28 GPa) shaft EF that has a steel (Gs=80 GPa) core.
For a 1-Gbps network operating over 5000 km, the delay is the limiting factor, not the bandwidth. Consider a Metropolitan Area Network (MAN) with the average source and destination 40 km apart. At
Compute the number of kilograms of hydrogen that pass per hour through a 5-mm thick sheet of palladium having an area of 0.4 m2 at 500°C.
A block and tackle system with nine supporting strands is used to lift a metal lathe in a manufacturing facility. The motor being used to wind the cable in the pulley system can provide 100 lb
A stationary radar operator determines that a ship is 19 km south of him. An hour later the same ship is 16 km southeast. If the ship moved at constant speed and always in the same direction, what was
Write a program that asks the user to enter the amount that he or she has budgeted for a month. A loop should then prompt the user to enter each of his or her expenses for the month, and keep a

Drivers are concerned with the mileage obtained by their cars. One driver has kept track of several tankful of gasoline by recording miles driven and gallons used for each tankful. Develop a c++
Strawberries contain about 15 wt% solids and 85 wt% water. To make strawberry jam, crushed strawberries and sugar are mixed in a 45:55 mass ratio, and the mixture is heated to evaporate water unt
Consider the following systems described by their difference equation. Find the transfer function and impulse response of the systems
A square 3m x 3m gate is located in the 45* sloping side of a dam. Some measurements indicate that the resultant force of the water on the gate is 500kN.(a)Determine the preassure at the bottom of the
The hot gas supply to a propulsion nozzle is at a pressure of 55kpa and temperature of 800K. the ambient pressure is 15kpa. If the ratio of specific heats is 1.33, approximately constant, and the mole
Determine the normal and tangential components of acceleration and the radius of curvature of the path of motion (a) at the moment the package is released at A, where it has a horizontal velocity of v
Plot the step response of the system at each value of t to yield over damped, under damped, critically damped and marginally stable responses
A man of mass m1 walks along a plank of length l with a constant acceleration a relative to the plank. The mass of the plank is m2 and the coefficient of friction between the plank and the ground is m
If a rod of 1025 steel 0.5 m (19.7 in) long is heated from 20 to 80 deg C (68 to 176 deg F) while its ends are maintained rigid, determine the type and magnitude of stress that develops. Assume that a
Suppose I have a charge on an insulator. If I touch it to a conductor, what happens? (Since charge doesn't flow on insulators, does the charge remain on the insulator? Is some of the charge tran
Create a ladder program to control a washing machine. This washing machine would have a fill cycle to one level, a 10 second wash cycle, a 10 second rinse cycle and then drain. Include a start bu
You run a 50ft extension cord to a load. The resistance of each conductor in the cord is 0.05Ω /foot. If the load were directly connected to the source voltage of 120V it would draw 10A.
A standardized procedure is expected to produce washers with very small deviation in their thicknesses. Suppose that 10 washers were chosen and measured.
I want to know if the equations I derived are correct ? and if they are not correct what is the correct equations for the 2 modes of operation. I need the circuit to be drawn ( with the voltages
Is it better to have several small wires conducting electricity or one big wire of the same cross section or better to have it the other way around? WHY?
