How to Make a Hand Model

Hand Model

Things needed

  • String
  • Pencil or Pen
  • Scissors
  • A card piece with the size of our hand

How to Make

  1. Place the card piece under your hand and sketch the outline it using a pencil or pencil.
  2. Once the hand is sketch cut the paper in the shape resembling the hand using the scissors.
  3. Cut the string into five pieces that would have the same length of your hand.
  4. Connect the string to every tip of every finger and the palm base. Attach the string to the card at the same place where there are joints in the fingers including the thumb.
  5. Try to pull the strings at the palm base and see the changes.

What Happens next

From your observation, you would have noticed that muscles are built mainly for the purpose of contraction and expansion and it is a highly important task. Students would realize that every movement they make is made by the muscular system of the human body that includes a simple smile to a heavy lifting of weights.

The muscles inside the forearm contains long tendons that run through the ligament fibers also called the carpal tunnel within the wrist. The coordination of these muscle help us to stretch even while showing a thumbs up. This would be the resultant of pulling the strings in the model hand.


Practise This Question

A ball falls from a height 'h' above the ground, collides and rebounds. The collision is perfectly elastic. At every moment the ball was moving under gravity and so has mg force downward i.e., towards the point of contact. Is mg "restoring force” in this motion. If yes, then is this motion SHM?
