Question
Which type of stress causes a change in the shape of a body without altering its volume?
Explanation
Shearing stress causes a change in the shape of a body by producing relative displacement of opposite faces (pure shear) without changing its volume. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Shearing stress. This satisfies dimensional consistency and physical conditions given, so option C is scientifically correct.
