90 degree bend - correct answer A bend that changes the direction of the conduit by 90 degrees
Back-to-back bend - correct answer Any bend formed by two 90 degree bends with a straight section of conduit between the bends
Concentric bends - correct answer 90 degree bends made in two or more parallel runs of conduit with the radius of each bend increasing from the inside
of the run toward the outside
Developed length - correct answer The actual length of the conduit that will be bent.
Gain - correct answer Because a conduit bends in a radius and not at right angles, the length of conduit needed for a bend will not equal the total determined length. Gain is the distance saved by the arc of a 90 degree bend
Offset - correct answer An offset is two bends placed in a piece of conduit to
change elevation to go over or under obstructions or for proper entry into boxes, cabinets, etc.
Rise - correct answer The length of the bent section of conduit measured from the bottom, centerline, or top of the straight section to the end of the conduit being bent
Segment bend - correct answer A large bend formed by multiple short bends or shots.
