6 - Question
Primitive methods should be preferred over mechatronic systems for short term manufacturing.
a) True
b) False
View Answer
Explanation: Primitive methods should be preferred over mechatronic systems for short term manufacturing. This is so because primitive methods are cheaper and easy to apply, whereas mechatronic systems are costlier and can be difficult to install and maintain in short run.
