1.Consider the flow field where angular velocity w is equal to 2pi rad/s ( a physical frequency of 1 Hz). Is this flow field compressible or incompressible ?
2.A particle moves along the path r = {(8 t2 )i + (t3 + 5)j} m, where t is in seconds. determine acceleration when t = 3 s.
3.Two similar cylindrical polished bars weighing 5.00 N each lie next to one another in contact.A third similar bar is placed on the other two in the groove between them.Neglecting friction,what horizontal force on each lower bar is necessary to keep them together.
4.If each cord can sustain maximum tension of 50N before it fails, determine the greatest weight of the flower pot the cords can support?
