The x component of velocity in an incompressible flow field isgivenbyu=Ax, whereA=2s−1 in meters. The pressure at point ðx, yÞ=ð0,0Þ is p0 =190kPa gage. The density is rho=1 :50kg=m3 and the z axis is vertical. Evaluate the simplestpossibley component of velocity. Calculate the fluid acceleration and determine the pressure gradient at point ðx, yÞ=ð2,1Þ. Find the pressure distribution along the positive x axis.

Amachine, modeled as a simple spring-mass system, oscillates in simple harmonic motion. its acceleration is measured to have an amplitude of 5,000 mm/s with a fre- quency of 10 hz. compute the maximum displacement the machine undergoes during this oscillation.
