(Leena - leave space for calculation)
2. The unit of force is =
3. The unit of stress is =
4. The unit of pressure is =
5. The unit of strain is =
6. What is the difference between pressure and stress
A. Pressure is the force exerted per unit area on the surface of an object,
typically acting perpendicularly to the surface. Stress is the internal
resistance of a material to an external force or deformation, expressed as
force per unit area within the material itself
