Answer

\frac{\Delta L}{L_0} $$

Here are the definitions for the given terms:

SECTION A

QUESTION 1: GENERAL

1.1 Resultant force

The resultant force is the single force that represents the vector sum of all individual forces acting on an object. It has the same effect on the object's motion as all the individual forces combined.

1.2 Elastic limit

The elastic limit is the maximum stress a material can withstand before it begins to deform permanently. If the stress exceeds this limit, the material will not return to its original shape once the stress is removed.

1.3 Strain

Strain is the measure of deformation of a material, defined as the ratio of the change in dimension to the original dimension. It is a dimensionless quantity. Strain=ΔLL0Strain = \frac{\Delta L}{L_0}

1.4 Hydrostatic pressure

Hydrostatic pressure is the pressure exerted by a fluid at rest due due to the force of gravity. It increases with depth and is given by the formula P=ρghP = \rho g h, where ρ\rho is the fluid density, gg is acceleration due to gravity, and hh is the depth.

1.5 Second moment of area

The second moment of area, also known as the area moment of inertia, is a geometric property of a cross-section that quantifies its resistance to bending or deflection. It describes how the area is distributed relative to an axis.
