Numerically integrate and plot the response of an underdamped system determined by m = 150 kg and k = 4000 N/m subject to the initial conditions of x0 = 0.01 m and 0 = 0.1 m/s, and the applied force F(t) = Φ(t) = 15 (t -1), for various values of the damping coefficient.
Use this "program" to determine a value of damping that causes the transient term to die out within 3 seconds. Try to find the smallest such value of damping remembering that added damping is usually expensive.

heat is transferred steadily to boiling water in a pan through its flat bottom at a rate of 650 w. if the temperature
The 0.6-kg mass is supported by two arms of negligible mass. The angle ? of the arms can be varied by changing the force F acting on the slid- ing collar. When ? = 70?, the assembly is rotating freely about the vertical axis with the angular velocity..
A water cooled compressor changes the state of R-134a from a saturated vapor at 15 psia to a pressure of 120 psia. The fluid rate is 2.0 lbm/min, and the cooling water removes heat at a rate of 135 Btu/min. If the power input is 4.0 hp, determine the..
The power cycle shown below operates under steady conditions and develops a net power output of 1.6 MW. The power cycle receives energy through one heat exchanger (heat exchanger 1) from steam condensing at a constant pressure of 225 kPa. The steam e..
