a.
To poke a hole just large enough to allow the cardboard to rotate freely when pinned through the hole.
a.
Explanation of Solution
The following are the steps to poke a hole into the cardboard-
- First cut out a large irregular shaped cardboard.
- Now take one edge of the piece of the cardboard.
- Near this edge poke a hole larger enough in such a way that the cardboard should be able to rotate freely when the pinned through hole.
- The most important thing is to have a proper hole which can hold the pin as well as the whole weight of the cardboard.
b.
To find the line, tie a weighted string to the pin. Then draw on the card board the line determined by the string.
b.
Explanation of Solution
The following are the steps to poke a hole into the cardboard-
- First cut out a large irregular shaped cardboard.
- Now take the middle line of the cardboard.
- This middle line will act the central line.
- Near this middle line poke a hole larger enough in such a way that the cardboard should be able to rotate freely when the pinned through hole.
- Finally tie as weighted string to the pin.
The obtained figure is −
c.
To repeat parts (a) and (b) but use a different hole.
c.
Explanation of Solution
Similarly, another can be taken on the cardboard to repeat the parts (a) and (b).
