- Hi Dad! Today we learnt about force, friction and pressure. I was wondering how we can use this in our daily life.
- Oh! Well, we use those three concepts while constructing also!
- Oh really? Can you tell me about it?
- Of course!
- Wow! So, we also use mechanical force in construction?
- There are many different types of forces like gravitational force. This force pulls the bricks toward the core of the Earth. This makes the bricks all pulled towards one side only.
- Yes!
- Oh wow! I didn't know that!
- Pressure is inversely proportional to the area of the surface, therefore most building have a wide surface area. This prevents the buildings to make a hole in the ground and fall. inside
- Sincefriction is theresistance that one surface or object encounters when moving over another, it provides a stop the bricks and prevents it from slipping.
- Now coming to Friction. Can you guess how we can use friction while constructing?
- That is absolutely right!
- Thank you, Dad, for telling me how we use FORCE, PRESSURE and FRICTION in CONSTRUCTION.
- Always here tohelp!
