Question

explain the relationship of stress to force applied to a certain body

Answer 1

Explanation:

Stress is the force per unit area on a body that tends to cause it to change shape. Stress is a measure of the internal forces in a body between its particles. These internal forces are a reaction to the external forces applied on the body that cause it to separate, compress or slide.

Answer 2

Answer: An external force operating across an object's cross section is measured by stress.

Explanation:

• N/m² (SI) or lb/in²are the units of force per area for stress (US).

• $\int\^ {df} \, = \int\limits^a_A {\alpha } \, dA$
  ∴$P =\alpha A$

• Common names for the SI units are Pascals, abbreviated Pa. We frequently come across 103 Pa = 1 kPa (kilo Pascal), 106 Pa = an MPa (mega Pascal), or 109 Pa = GPa since the 1 Pa is uncomfortably little in comparison to the loads that most constructions experience (giga Pascal)
• A building may encounter one of two types of stress: Shear stress and regular stress. A force exerts a normal stress when it works perpendicular (or "normal") to an object's surface. Shear is the result of a force acting parallel to an object's surface.
• In fact, even in the absence of a load being applied, stress can still exist in a material. This is called residual stress, and it can be used to toughen materials, as it was when the Japanese Katana sword was being made.
