A 150mm-diameter hollow sphere weighing 300 N is attached to a solid concrete block weighing 5.3 kN. If the concrete has a specific weight of 27.7 kN/m3, what will be the state of the two
A 150mm-diameter hollow sphere weighing 300 N is attached to a solid concrete block weighing 5.3 kN. If the concrete has a specific weight of 27.7 kN/m3, what will be the state of the two objects together in water?
The water in an 8-m-diameter, 3-m-high above-ground swimming pool is to be emptied by unplugging a 3-cm-diameter, 25-m-long horizontal pipe attached to the bottom of the pool. Determine the maximum discharge rate of water through the pipe. Also, explain why the actual flow rate will be less.
Q1- Consider a continuous time signal x(t)=2cos(21πt+30)+5cos(18 πt)
a) What is the signal frequency and What is the Nyquist rate of the signal?
b) Write a MATLAB M function or a script called sampley4p1 to perform
sampling:
1- Compare the results when the sampling frequencies of 10Hz , and 30 Hz were
used for the time between zero and 0.2sec?
2- determine the sampling frequency which result in the problem of aliasing .2-
Q2- a) suppose that the resulting samples from the Q1 (part a) passed through a 4
bits A/D convertor,
write a MATLAB code to perform the quantization, your MATLAB code and the
report should result in a figure contain the samples and the quantized values in the
same figure for comparison.
