Stress is given as
Stress = force / area
The unit of force is Newton or Kg·m/s² and that of area is m².
Therefore, the unit of stress will be N/m² or Kg/m ·s²
The dimensional formula for force is [ M¹L¹T⁻²] and that of area is [L²]
Therefore the dimension of stress can be calculated as
Stress = [ M¹L¹T⁻²]/ [L²]
=[M¹L⁻¹T⁻²]
The dimensional formula will be [M¹L⁻¹T⁻²]
