He identified six levels in education that most educatorsconsider during teaching. Later on, a former student of Bloom revised the learning taxonomy bychanging the names in the six categories from noun to verb forms, and slightly rearranging them.As a quick review, the six levels of Bloom’s cognitive domain in the original and revised formsare presented in Figure 1.0 below.

Based ona free-body diagram, the system differential equation is expressed in (1). Using LaplaceTransform, this time-domain equation leads to a position-to-external force transfer functiongiven by equation (2). Once the transfer function is derived, a set of parameter values (m = 0.1kg, b = 1 N*s/m and k = 2 N/m) is used to obtain the system transfer function shown in (3

INTRODUCTIONTo control a system in order to get a desired performance has been the longest desire of engineersand planners. The control requirements may be of different kinds: a) to stabilize an unstable system,b) to change the state of a system from one to another, C) to track the output of a system to a knownvariable, and d) to regulate the performance of a system in the face of variable inputs, loading ofoutput, disturbances and external noise. The list is endless depending on the type of application.Learning to control a system requires learning and developing a repertoire of tools for 1. Modeling of systems, 2.

It includes an adjustableframe adjusted by wing nuts and one bolt for securing the machine (figure 2b). Making the guard adaptableallows the operator to set the exact amount of belt he or she needs to be exposed, ultimately reducing thework envelope and reducing the contact with the belt. Using wingnuts allows the operator to make
