Answer:
Forces of tension and compression in pre-stressed concrete remain unchanged but lever arm changes with the moment. This can be explained as follows:
Forces of tension and compression in pre-stressed concrete:
- Pre-stressed concrete is a type of reinforced concrete in which high-strength steel strands or tendons are tensioned before the concrete is cast.
- The tensioned tendons are anchored to the concrete at the ends and are then released, causing them to exert a compressive force on the concrete.
- This compression counteracts the tensile stresses that occur when the concrete is subjected to external loads, such as the weight of a building or bridge.
Lever arm in pre-stressed concrete:
- The lever arm is the distance between the force and the point where it is applied.
- In pre-stressed concrete, the lever arm changes with the moment, which is the tendency of a force to cause rotation around a point.
- When a moment is applied to a pre-stressed concrete member, such as a beam or slab, the lever arm changes as the point of application of the force moves closer or further away from the point of rotation.
- This change in lever arm affects the distribution of stresses within the member and can lead to cracking or failure if not properly accounted for in the design.
Conclusion:
In conclusion, forces of tension and compression in pre-stressed concrete remain unchanged, but the lever arm changes with the moment. This change in lever arm must be taken into account in the design of pre-stressed concrete members to ensure their safety and durability.
