The first topic, which I am going to cover, is introduction to the area of measurements.
Mechanical measurement is a sort of a subset of what we can call measurement. Therefore,
introduction to measurements will be a general description of what measurements means and then
of course, we will later look at what mechanical measurements are.
When you do any measurement, in whatever field it is, the measurement process is prone to some
errors. Even before we start looking at the specific measurements and how we do it and so on, it
is good and necessary to understand about these errors, how to either minimize them or to
characterize them and so on. So the errors in measurements form the topic, which will be given
emphasis to start with. When we talk about errors there are some statistical principles, which are
required to understand the nature of errors.
Of course, when we go into the specific topic, we will give more details. Right now, it is
sufficient to understand that there are some statistical principles involved in characterizing of
errors and that will be the topic that we are going to look at
