Unformatted text preview: b) The reaction force exerted on the hose in the x direction, in Newtons. 3) The temperature in Lafayette is 70deg. The temperature in Delphi, 8 miles away, is 80deg. You drive from Lafayette to Dephi at 30mph. Plot AAE333 Fall 2010 temperature as a function of time as measured by your car thermometer during the trip. What is the rate of increase of temperature (in deg / hr) measured in your car? 4) Let T=70+ x/.8, where x ranges from 0 to 8. If the velocity is 30, what is the substantial derivative of T? 5) Consider a probe that measures the height of a surface (like a CD).The surface is a disk spinning at a constant rpm of 3000. The surface of the disk is corrugated in a sinusoidal pattern, with a height of .01 sin( ) mm. The probe sits at a radius of 5 cm from the center of rotation of the disc. What is time rate of change of surface height as measured by the probe?...
