Solution:

What is the difference between pressure and stress, even though their units are the same (N/mm²)?

Pressure is the external force applied on a body, while stress is the internal force of the body to resist the external force

There is no difference between them

Stress is the external force applied on a body, while pressure is the internal force of the body to resist the external force
