See Exercise 9.15 in the Chapter 9 Programming Exercise from the Book section for the description of this exercise.

Sample Run
Enter the real part of the first complex number: 3.5
Enter the imaginary part of the first complex number: 6.5
Enter the real part of the first complex number: -3.5
Enter the imaginary part of the first complex number: 1
(3.5 + 6.5i) + (-3.5 + 1i) = (0.0 + 7.5i)
(3.5 + 6.5i) - (-3.5 + 1i) = (7.0 + 5.5i)
(3.5 + 6.5i) * (-3.5 + 1i) = (-18.75 - 19.25i)
(3.5 + 6.5i) / (-3.5 + 1i) = (-0.43396226415 - 1.98113207547i)
|(3.5 + 6.5i)| = 4.47213595499958.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

Aloaded platform of total mass 500 kg is supported by a dashpot and by a set of springs of effective stiffness 72 kn/m. it is observed that when the platform is depressed through a distance x = 12.5 cm below its equilibrium position and then released without any initial velocity; it reaches its equilibrium position in the shortest possible time without overshoot. find the position and velocity of the loaded platform 0.10 sec. after its release. if a further load of 400 kg is added to the platform, find, i) the frequency of damped vibrations, and i) the amplitude of vibration after 2 complete oscillations, given that the initial amplitude is 15 cm.

Coiled springs ought to be very strong and stiff. si3n4 is a strong, stiff material. would you select this material for a spring? explain.
