Problem 8-21

A man attempts to support a stack of books horizontally by applying a compressive force of F = 120 N to the ends of the stack with his hands. If each book has a mass of 0.95 kg, determine the greatest number of books that can be supported in the stack. The coefficient of static friction between his hands and a book is (ms)h = 0.6 and between any two books (ms)b = 0.4. F 120 N F 120 N Prob. 821

Step-by-Step Solution:
Step 1 of 3

ECE 4190/6190, Electric Machines and Drives, Spring 2016 Create a simulation to verify Dc Drive Example 1 and Dc Drive Example 3 from the class notes. Note that the gains for the PI controller for the speed control are Kp1 = 100 Ki1 = 20 and the gains for the PI controller for the current control should be Kp1 = 0.005 Ki1 = 5 and the cut­off frequency for the low­pas filter (LPF) is fc = 3kHz Turn in the details of the simulation. Also submit the waveforms that correspond to the notes (same variables, same variable placement, same axes, etc.) Dc Drive Example 1： Dc Drive Example 3：
