1. A 12 Kg mass is statically suspended from a load cell and the load cell deflection caused by the mass is 0.02 mm. Estimate the natural frequency of the load cell. (use three significant figures).
2. If the load cell is assumed to be a second-order system and is critically damped, determine the maximum frequency up to which the load cell can measure dynamic loads with an inherent error of less than 10%.
3.What is the maximum frequency for 0.9 amplification ratio and if the frequency ratio was 0.5?
4.What is the minimum frequency for Question 2?
5.What frequency response will you have if the same system is not damped? (
|
a) The system will oscillate at a fixed frequency and then will stop. |
||
|
b) The response is the same as for the previous question 5.c. |
||
|
c) There will be three frequency responses. |
||
|
d) The response will be in two frequency ranges. |
||
|
e) The system will not oscillate (f = 0Hz). |
||
|
f) The response is an infinite amplification ratio. |
||
|
g) The response will be in the DC domain. |
||
|
h) The system response will be under 44 Hz. |

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
