The document contains an assessment for an Industrial Automation and Control course. It includes 11 multiple choice questions testing understanding of concepts like control systems, automation pyramids, production systems, and sensor systems. Correct answers are required for topics such as the advantages and disadvantages of open and closed loop control systems, calculating profits from different machine types, appropriate automation types for different manufacturing processes, mapping production systems to product types, identifying subsystems in a sensor system, and levels in an automation pyramid. The assessment is part of an online course aimed at building knowledge of industrial automation and control systems.

2) Suppose a company buys two types of band saw machines for cutting steel ingots
brought in by customers to dimension namely, Manual and Automatic, taking a loan
from a bank to be paid back in 24 equal monthly instalments. From figures given
below for each machine, compute the amount of profit/machine the company can
earn from each type of machine in 2 years by cutting ingots for 200 hours/month
assuming enough demand such that the machines cut every day neglecting times for
maintenance.
