​Fulcrum

​- A point on a beam that support and balance the beam

​

​Load

​- The weight of an object

​

​Force

​- The push or pull action which gives effect of an object

​THE RELATIONSHIP BETWEEN LOAD, FULCRUM AND LOAD

​

• ​The closer the load from fulcrum, the lesser the force that is needed to lift the load

​( Semakin dekat kedudukan beban dengan fulkrum, semakin sedikit daya yang diperlukan untuk mengangkat beban)

​

• ​The further the load from the fulcrum, the greater the force that is needed to lift the load.

​​( Semakin jauh kedudukan beban dengan fulkrum, semakin banyak daya yang diperlukan untuk mengangkat beban)
