I appreciate the Motor torque example as this is one of the perennial problems that a first team faces. Using SI units is a good thing. Creating clear definitions each put in a separate box helps with readability. Sometimes including an equation in the box is helpful for quick reference while reading an example. It is good to note that the motor must produce a lifting force not equal to but greater that the load in order to lift the load in a timely manner.

Ratios are another simple but important item. You covered speed vs torque but surprisingly many students do not know how to calculate the max speed of a drive with a CIM - Tough box even data sheets in front of them.
