1. Tension Force (T): This is the force exerted by the crane's cable on the object. It acts upwards, directly opposing gravity and keeping the object suspended.
2. Gravitational Force (Fg): This is the force of gravity acting on the object, pulling it downwards. Its magnitude is calculated as:
```
Fg =m * g
```
어디:
* m은 물체의 질량입니다
* G는 중력으로 인한 가속도입니다 (약 9.8m/s²)
3. Air Resistance (Fair): This force opposes the object's motion through the air. Its magnitude depends on the object's shape, size, and velocity. 그것은 물체의 움직임의 반대 방향으로 작용합니다.
4. 다른 외부 세력 : This can include:
* Wind Force (Fw): If there's wind, it will exert a force on the object depending on its direction and speed.
* 마찰 (ff) : If the object is in contact with another surface, friction will oppose its motion. This is usually negligible compared to the other forces involved.
평형 :
When the crane is holding the object stationary, the forces are balanced. 이것은 다음을 의미합니다.
```
T =Fg + Fair + Fw + Ff
```
중요한 참고 : 이 힘의 크기는 물체의 질량, 크레인의 리프팅 용량 및 환경 (바람, 공기 저항 등)에 따라 변할 것입니다.
