Question
Chapter 2, Problem 3CCO
To determine
To Illustrate:
The business process model used by a computer service technician using wearable technology glasses to fix a broken computer.
Solution:
A Computer repair Technician can follow the business process model as explained with the help of a flow model below:
- The technician either go the customer or get the computer to its office using any courier service.
- The technician should scan the computer using the wearable glasses to collect the data.
- Once the data is collected, technician can analyses the data using the wearable glass itself and must register the issues using the same wearable glass.
- The technician can retrieve the computer manuals using the wearable glass and determine how to fix the issues using the wearable glass.
- Now the Computer Technician just need to follow the method mentioned in the manual to fix the issue.
- Now the computer Technician should run the computer to check that whether the issues have been fixed properly or not.
- If issues has been fixed then register using the glass that issue has been fixed. If Not Go back and scan again and following the process again.

PROBLEM 18.103
A 2.5 kg homogeneous disk of radius 80 mm rotates with an
angular velocity ₁ with respect to arm ABC, which is welded
to a shaft DCE rotating as shown at the constant rate
w212 rad/s. Friction in the bearing at A causes ₁ to
decrease at the rate of 15 rad/s². Determine the dynamic
reactions at D and E at a time when ₁ has decreased to
50 rad/s.
