Question : 167 of 200

Marks: +1, -0

Which one of the following statements is correct?

Shear cracks start due to high diagonal tension in case of beams with their webs and high prestresing force.
Shear design for a prestressed concrete beam is based on elastic theory
In the zone where bending moment is dominant and shear is insignificant cracks occur at 20° to 30°
After diagonal cracking, the mechanics of shear transfer in a prestressed concrete member is very much different from that in reinforced concrete members.
