Consider the equation of motion of a first-order system:
a. what is the bandwidth of the system?
b. find the steady-state response of the system considering only those components of f(t) that lie within the bandwidth of the system.
1. (a) In your own words describe briefly the phenomenon of luminescence. (b) What is the distinction between fluorescence and phosphorescence?
A steel strut is pinned at both ends. The strut has a solid circular cross section and is 6 m long. The strut collapses under a load of 100 kN. Calculate the diameter of the strut
A meteorologist uses a pitot -static tube to measure the wind speed in a tornado. Based on the damage caused by the storm, the tornado is rated as EF5 on the enhanced Fujita Scale. This means that the wind speed is estimated to be in the range of 261..
A closed system undergoes a process in which there is a heat transfer of 110 btu into the system. The work done on the system is 70 btu. Initial internal energy of the system is 1300 btu, what is the final energy of the system in btu.
An input 422 ft-lb of torque from the torque converter.
Air enters a constant-area duct with MI = 2.95 and 1) = 500°R. Heat transfer decreases the outlet Mach number to M2 = 1.60. Compute the exit static and stagnation temperatures.
A race car starting from rest travels along a straight road and for 10 s has the acceleration shown. Construct the v - t graph that describes the motion and find the distance traveled in 10s.
refridgerant 410a is initially at 120 f and quality of 30. it undergoes a constant-pressure process. the final state is
for the piping diameter changes and flow directions shown below if the velocity at the input is 5 ms the initial
Refrigerant 134a enters a 28-cm diameter pipe steadily at 200 kPa and 20C with a velocity of 5 m/s. The refrigerant gains heat as it flows through the pipe and leaves the pipe at 180 kPa and 40 C.
Atubular heat exchanger is used for this with the solution flowing about 1.2 m/s in 25 mmbore iron tubes and being heated by wet steam at 115OC. The length of the tubes is not toexceed 3.5m . Taking inside, and outside heat transfer coefficient as..
an axial piston pump delivers 0.002 m3s at 3300 rpm. it has nine 16-mm diameter pistons arranged on a 135-mm piston
