The sum of strains in 3 mutually perpendicular directions.

YES, This answer is right. When the beam is having more than two supports that kind of beam is called Continuous beam.

Yes the above answer is right.

The point of contraflexure will occur only in over hanging beam.

The spring index is the relationship between the mean diameter and wire diameter.

In fixed beam the both ends of the beam will be fixed in a concrete wall or with some other basement, In Continuous beam the beam which has supports more than two, in this beam there are two supports at the both ends of the beam and the remaining supports are placed between these two end supports continuously

The beam which has Supports more than two is called as continuous beam, In this beam there are two supports at the both ends of the beam and the remaining supports are placed between these two end supports continuously,
