A flow is described by velocity field~V=axˆi+bˆj, wherea= 1/5 s−1andb= 1 m/s. Coordinates are measure in meters. Obtain the equation for the streamline passing throughpoint (1,1). Att= 5 s, what are the coordinates of the particle that initially (att= 0)passed through the point (1,1)? What are its coordinates att= 10 s? Plot the streamlineand the initial, 5 s, and 10 s positions of the particle. What conclusions can you draw aboutthe pathline, streamline, and streakline for this flow?

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.
