Question

Beam balance used to measure the mass of objects belongs to _______ (class l/class 3) levers.

Answer 1

Class 1 lever:

1. Class 1 levers consist of those machines which have a fulcrum in between the load and effort.
2. In one pan we have the objects whose load is to be measured, and in the other pan, we carry the weight for measurements.
3. Both effort arm and load arm are equal.
4. So load and effort take the end locations, while the fulcrum will lie in between.

Hence, beam balance used to measure the mass of objects belongs to class 1 levers.
