Please provide an example of INTERNAL and EXTERNAL torque

[zinedine_88]

Can anybody please give me an example of INTERNAL and EXTERNAL force.

I was told by my Professor that there is only internal Torque at the moment when you are running toward a marygoround and grab so of the handles.
PLEASE EXPLAIN ME WHY.

Internal torque refers to the rotational force that is generated within a system, while external torque refers to the rotational force applied from outside the system. An example of internal torque can be seen when you are running towards a merry-go-round and grab onto the handles. As you push and pull on the handles, you are generating internal torque within your body, specifically in your arms and shoulders, to rotate the merry-go-round. This is because your muscles are contracting and pulling on your bones to create the necessary force to rotate the object. On the other hand, if someone were to push the merry-go-round from the outside, they would be applying external torque to the system. This external force would cause the merry-go-round to rotate, but the force is not generated within the system itself.
