Introduction: Do-it-yourself Dynamometer
For the construction of the dynamometer we will need:
-2 (or more) metal tuna cans
-1 metal staple
- A sheet of paper 4 cm wide and 30 cm long (or more)
-1 or 2 weighs of 102g
- In the absence of a protruding surface 1 nail
Teachers! Did you use this instructable in your classroom?
Add a Teacher Note to share how you incorporated it into your lesson.
Step 1: FIND a PROTRUDING SURFACE
look for a robust one! in fact, it must be used to support the structure of the dynamometer
Step 2: DIVIDING a SHEET IN CENTIMETERS
the sheet obtained will be inserted into the protruding surface, therefore create a hole with the diameter necessary for the entry of the surface
Step 3: INSERT THE ELASTIC INTO THE EXTENDING SURFACE
if possible use a medium-sized elastic, in fact if the latter were too small, there would be a risk of breaking once a weight was placed on it
Step 4: HOOK (BY a CLIP) THE ELASTIC TO a TUNA BOX
if done correctly we will see that the elastic will undergo a stretch.
Step 5: MAKE THE PROPORTION
therefore carry out the proportion between the elongation of the elastic with the tuna cans compared to the elongation with 1 weight of 102 g (1 newton)
