Strength of Materials: Internal Forces, Simple Stress, and Analysis
1.1 Strength of Materials
The study of material resistance extends the concepts of forces from mechanics, but there’s a clear distinction between the two. Mechanics primarily focuses on the relationships between forces acting on a solid object. Statics analyzes solids at rest, while dynamics studies solids in motion, although dynamic equilibrium can be established by incorporating inertial forces. In contrast, strength of materials investigates the relationship between externally applied loads and

SI Units
The basic units in the SI (International System of Units) system are as follows:
- Meter (m) for length
- Kilogram (kg) for mass
- Second (s) for time
- Ampere (A) for electric current
- Kelvin (K) for temperature
- Mole (mol) for amount of substance
- Candela (cd) for luminous intensity
Triangle Law of Vector Addition
The triangle law of vector addition states that if two vectors are represented by two sides of a triangle in magnitude and direction, then their resultant vector is represented by the third side

Static Electricity
Static electricity is the result of an imbalance between positively and negatively charged objects.
Types of Forces Between Electric Charges
- Like charges repel.
- Unlike charges attract.
How is Static Electricity Generated?
- The force of friction causes charging. When you rub two different materials together, friction transfers electrons from one material to another.
- Electrons have negative charges and are relatively loosely held to the atom, so they can be easily pulled away by friction.

San Lorenzo
The facade of San Lorenzo features relatively coarse stonework, particularly in the facade, which was never clad in marble as initially planned. However, the structure maintains a perfect harmony, showcasing the different heights of the central nave, the side aisles, and the chapels. At the back stands the slightly pointed dome crowning the crossing.
Inside:
The interior features a Latin cross plan articulated with three naves and side chapels, a transept, and a main apse flanked by two
