A driven non-linear oscillator satisfies the equation
x·· + ∈x·3 + x = cos pt,
where ?, p are positive constants. Use perturbation theory to find a two-term approximation to the driven response when ? is small. Are there any restrictions on the value of p?
Molten sodium metal is often used as a coolant in nuclear reactors. Consider molten sodium at 205 C flowing at a rate of 0.23 m/s over a plate with length and width of 1 m and 2 m, respectively.
consider a space ship in a stationary orbit around a planet. the potential energy of the ship is u-kmr where kgm is
Draw axial load, shear, bending moment, and torque diagrams for the shaft.
The skid-steer loader has a mass of1.18Mg,and in the position shown. The center of mass is atG1.There is a320-kgstone in the bucket, with center of mass atG2.There is a similar linkage on each side of the loader. Determine the magnitude of the reacti..
a long power transmission cable is buried at a depth ground to cable centerline distance of 2 meters. the cable is
What is the acceleration of the aircraft (in m/s2)? How long does it take the aircraft to reach its take-off speed?
In the off-mode the chip is in thermal equilibrium with the coolant (Ti = T8). When the chip is energized, however, its temperature increases until a new steady-state is established.
a cylinder - piston system contains 4 kilograms of liquid water liquid and vapor saturated at 35 c. a piston
Using constant specific heat method
Water at 10C and a velocity of .6 m/s flows over one surface of a 1.5 m long flat plate maintained at 44C. Consider the following: Determine the heat transfer rate per unit width (W/m) from plate.
Determine the angle theta degrees that requires the minimum torque T to keep the seam closed. (Hint: use Mohr's circle). Give the answer in degrees.
