Diagramma tensione-deformazione per l’acciaio
Prova di trazione
Nel tratto OP l’andamento è lineare: la deformazione è di tipo elastica. La pendenza del tratto retto definisce il modulo elastico E del materiale. Nel tratto PE iniziano a verificarsi deformazioni permanenti di lieve entità. Il punto E rappresenta il limite del campo elastico, oltre il quale avviene la deformazione plastica. Nel tratto ES si osserva un graduale passaggio dal campo elastico a quello plastico. Il punto S, detto
Chemistry uses math for measuring, calculating, and comparing data.
Uses SI Units (grams, liters, meters, kelvin, etc.).
Conversions are common (like grams to kilograms).
Accuracy and precision matter in all experiments.
Example: Measuring 25.0 mL of water = precise data.
Steps: Ask a question → Form a hypothesis → Experiment → Collect data → Analyze → Conclude.
Managing financial resources to achieve long-term organizational goals.
Integrating financial strategy with overall corporate strategy.
Financial Planning and Forecasting: Aligning financial goals with the strategic plan.
Investment Decisions (Capital Budgeting): Selecting long-term projects that align with strategic objectives.

Nikvistov kriterijum zahteva da frekvencija semplovanja mora biti bar dva puta viša od
najviše frekvencije sadržane u ulaznom signalu. Ukoliko ovaj uslov nije ispunjen dolazi do
pojave tzv. alijaze (alliasing). Sledi potpunija definicija Nikvistovog kriterijuma:
Signal sa maksimalnom frekvencijom fa mora biti semplovan frekvencijom fs > 2fa. Ovim
se garantuje da će u digitalni domen biti preneta potpuna informacija o signalu.
Alijaza nastaje kada je fs < 2fa

## **1. a) Define Java Bytecode. Justify that Java is platform independent
**Java Bytecode** is the intermediate code generated by the Java compiler after compiling a Java program. When you write a Java source file (`.java`) and compile it using `javac`, the compiler converts it into a bytecode file (`.class`). This bytecode is not specific to any machine and can be executed by the **Java Virtual Machine (JVM)** on any platform.
**Platform independence** means that a Java program can run on any
