Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Question

### Understanding Cantilever Beam Deflection

#### Theory and Equation

In this section, we explore the concept of cantilever beam deflection. A cantilever beam is fixed at one end and free at the other, and the beam bends when a force is applied at the free end.

The formula to calculate the force \( F \) required to deflect the end of a cantilever beam is given as:

\[
F = \frac{3EI}{L^3} x
\]

Where:
- \( E \) is the modulus of elasticity of the material.
- \( I \) is the area moment of inertia of the beam's cross-section.
- \( L \) is the length of the beam.
- \( x \) is the deflection of the beam at the end.

#### Diagram Explanation

The diagram (Figure 4.32) shows a cantilever beam subjected to a force at its free end:

- The beam is horizontally positioned, fixed at \( x = 0 \) and free at \( x = L \).
- The beam is bending due to the force \( F \) applied at \( x = L \).

#### Problem Statements

1. If a mass \( m \) is attached to the end of the beam, determine the equation of motion for the vertical motion of the beam.

2. If the length of the beam is doubled, analyze the effect on the frequency of the free vibration of the beam.

This conceptual understanding aids in predicting the behavior of materials under stress, vital for fields such as structural engineering and materials science.
