What’s torque?

Torque is an instantaneous force that rotates an object around its rotary shaft. Torque expresses the necessary force when moving an object. For example, when riding a bicycle, torque is the pushing force of the pedal. If you are pushing the pedal strongly, then the torque is greater.
 The greater the force required to support the lid, and the greater the length of the object, the greater the objects torque will be.

Example calculation in case of toilet lid
Weight: 1kgf(=9.8N)
Length: 0.4m(gravity point=0.4m/2=0.2m)
The following TOK dampers would be suitable!
