An example of our digital worksheets is shown below. It utilises HTML text boxes, Flash animations, Flash input boxes and Flash "dragging objects". Students type their answers into the text boxes and Flash input boxes, drag their chosen arrows to the correct places then print the completed worksheet for marking and for their records.
Our mechanisms Module software contains HTML and PDF versions of this exercise.
 
1. Mechanical systems have at least 3 parts, an input, a process and an output.
Give three examples of inputs in a mechanical system.
2. Mechanical systems have at least 3 parts, an input, a process and an output.
Give three examples of mechanisms in a mechanical system.

3. Describe 5 subsystems that are found on bicycles. Click on a subsystem text box to start typing in it. Type your answers into the text boxes.

4. Describe what the input, process and output is in the jigsaw system. Click on the input, process and output text boxes to start typing in them. Type your answers into the text boxes.

5. Describe what the input, process and output is in the reciprocating sander system. Click on the input, process and output text boxes to start typing in them. Type your answers into the text boxes.

6. Describe what the input, process and output is in the circular saw system. If the circular saw is used for long periods, the motor may overheat. Show how "feedback" in the system could prevent the saw motor from overheating and damaging the saw. Click on the text boxes to start typing in them. Type your answers into the text boxes.

7. Describe what the input, process and output is in the wood lathe system. If one of the doors to the drive mechanism is opened, someone could get caught in the moving parts of the machine. 

Show how "feedback" in the system could prevent the motor from running when one of the doors is open.
Click on the text boxes to start typing in them. Type your answers into the text boxes. Complete the diagram by choosing appropriate arrows and dragging them to their correct positions.
