Q1. How does a prestressed precast concrete bridge beam work?

How does a pre-stressed concrete bridge beam work? The strands inside the beam would be compressed applying a significant amount of force by pulling them back, the concrete is casted around the strand, then releasing the strands applying compressing force into the beam.
