Engineering Formulas Explained
The Best Engineering Calculator uses several fundamental engineering equations.
1. Ohm’s Law Formula
Ohm’s Law describes the relationship between voltage, current, and resistance in an electrical circuit.
The main formula is:
V = I × R
Where:
| Symbol | Meaning | Unit |
|---|---|---|
| V | Voltage | Volt (V) |
| I | Current | Ampere (A) |
| R | Resistance | Ohm (Ω) |
The calculator can also rearrange the formula:
Current:
I = V ÷ R
Resistance:
R = V ÷ I
Example:
If:
- Voltage = 12 V
- Resistance = 4 Ω
Current:
I = 12 ÷ 4
I = 3 A
The electrical current is 3 amperes.
2. Electrical Power Formula
Electrical power represents the rate at which electrical energy is consumed or produced.
The formula is:
P = V × I
Where:
| Symbol | Meaning | Unit |
|---|---|---|
| P | Power | Watt (W) |
| V | Voltage | Volt (V) |
| I | Current | Ampere (A) |
Example:
Given:
- Voltage = 120 V
- Current = 5 A
Power:
P = 120 × 5
P = 600 W
The electrical power is 600 watts.
3. Stress Calculation Formula
Stress measures the internal force experienced by a material when an external force is applied.
The formula is:
Stress = Force ÷ Area
Where:
| Symbol | Meaning | Unit |
|---|---|---|
| Force | Applied force | Newton (N) |
| Area | Surface area | m² |
| Stress | Material stress | Pascal (Pa) |
Example:
Given:
- Force = 500 N
- Area = 0.25 m²
Stress:
Stress = 500 ÷ 0.25
Stress = 2000 Pa
The resulting stress is 2000 Pascals.
4. Density Calculation Formula
Density describes how much mass exists in a specific volume.
The formula is:
Density = Mass ÷ Volume
Where:
| Symbol | Meaning | Unit |
|---|---|---|
| Mass | Amount of material | kg |
| Volume | Space occupied | m³ |
| Density | Material density | kg/m³ |
Example:
Given:
- Mass = 20 kg
- Volume = 4 m³
Density:
Density = 20 ÷ 4
Density = 5 kg/m³
The density is 5 kg/m³.
5. Force Calculation Formula
Force is the push or pull acting on an object.
The formula is:
Force = Mass × Acceleration
Where:
| Symbol | Meaning | Unit |
|---|---|---|
| Mass | Object weight | kg |
| Acceleration | Rate of motion change | m/s² |
| Force | Applied force | Newton (N) |
Example:
Given:
- Mass = 10 kg
- Acceleration = 5 m/s²
Force:
Force = 10 × 5
Force = 50 N
The required force is 50 Newtons.
Practical Example Using Multiple Engineering Calculations
Consider an electrical device with:
- Voltage = 24 V
- Current = 3 A
To calculate electrical power:
P = V × I
P = 24 × 3
P = 72 W
The device uses 72 watts of power.
Now consider a mechanical object:
- Mass = 15 kg
- Acceleration = 4 m/s²
Force:
F = 15 × 4
F = 60 N
The object experiences 60 Newtons of force.
These examples show how engineering formulas help solve real-world problems.
