1. A unity feedback system has open-loop transfer function given by an 100 G(s)s2)(s +4) a. Use analytical techniques (i.e. without using any plots) to estimate the closed-loop: i. Resonant frequency, w (8 marks) ii. Resonance peak, Mp (in decibels) (2 marks) i. Phase at w = 3rad/s (2 marks) b. Obtain a table for the response of the open-loop transfer function for a set S of frequency values, where S {1.5,3,5,7, 10, 15, 20} rad/s (8 marks) Hence draw...
In the laboratory, a paste specimen was prepared using 45 g of water and 100 g of cement then sealed to prevent the loss of water. The paste specimen was cured for 28 days in the constant room temperature. After the 28 days of curing period, a sample from the paste specimen was obtained by breaking off the specimen and the sample was dried in the oven at 105°C for 24 hours. After this oven drying, the sample was then...

Using the second set of data, plot a graph of Total Mass on the x-axis and average acceleration on the y-axis. Under "Analysis" select "Automatic Curve Fit" and choose inverse relationship. Print two copies of this graph. Include a copy of your graph with your report. You will also need a second copy for later. What do you think the physical meaning of the constant term in the equation is? 10. Total Moving Mass Acceleration (m/s (cart, contents and hanging...
