Answer 2

When a rod is heated but prevented from expanding , the stress developed is independent of​ length of rod.

Explanation:

• Stress is a physical quantity that defines force per unit area applied to a material.
• The maximum stress of material can stand before it breaks is called the breaking stress or ultimate tensile stress. Tensile means the material is under Tension. The forces acting on the material are trying to stretch the body.
• There are six types of stress: compression, tension, shear, bending, torsion, and fatigue. Each of these stresses affects an object in different ways and is caused by the internal forces acting on the object. The internal forces are the result of how forces are applied to an object.
• The stress equation is σ = F/A . F denotes the force acting on a body and A denotes the area. Units of stress are the same as units of pressure - Pascals (symbol: Pa) or Newtons per squared meter.
