Conduit 2

By tracking   ?  , the degree of bend can be accurately replicated based on the amount of conduit drawn into the shoe.

Travel

Mechanical and electric benders have a   ?   to keep the conduit tightly supported within the shoe.

Back support

The amount of travel of a 45° bend is half the amount of travel of a   ?   bend.

90°

The   ?   is the difference between take-up and gain.

Setback

When setting up mechanical and electrical bending equipment, it is necessary to level the   ?   from the front to back and side to side in order to create accurate bends.

Shoe

Mechanical benders are more suited for bending 90° bends and offsets and cannot be used for bending saddles.

False

A   ?   is fabricated with a mechanical or electric bender using the multiplier method or measured rise method.

Kick

When using mechanical and electric benders to bend a 90° bend, the operator will bend the conduit 3° to 5° past the 90° mark to account for   ?  .

Springback

Using the   ?   on a mechanical bender as the benchmark for making a 90° bend is similar to using the arrow on a hand bender

Front of the hook

Using the   ?   on a mechanical bender as the benchmark for making a 90° bend is similar to using the arrow on a hand bender.

Travel

Which of the following elements is not required when charting a mechanical or electric bender?

Springback

A double-acting cylinder has   ?   hoses or connections with the cylinder

2

One-shot benders can bend conduit up to   ?   in size.

4”

Hydraulic benders use   ?   to push a ram component of a cylinder to move a shoe, which bends conduit.

Hydraulic pressure

When hydraulic benders are charted for angles less than 90°, the ram travel of the desired bend angle and the   ?   mark are recorded.

Center of the bend

Some hydraulic bender manufacturers have a chart located on the bender yoke that indicates the ram travel for common bend angles.

True

The ability to bend conduit in one motion makes   ?   benders very efficient.

One-shot

When using a one-shot hydraulic bender, travel is calculated using a   ?  .

Travel rod

Multiple-shot benders can bend conduit up to   ?   in size.

6”

When using the multiplier method to bend a kick with a hydraulic bender, the   ?   indicates when the desired degree of bend has been obtained.

Ram travel

When there are an even number of shots for a segmented bend, there is no bend at the exact center of the developed length.

True

The length of conduit within an electrical box is the   ?   length.

Thread

When marking an even number of bend marks for a segmented bend, the center of the developed length will be   ?  .

Located between two bends

The radius of an object can be determined by taking the diameter and   ?  .

Dividing it by 2

When planning concentric bends, various calculations need to be made based on the   ?   of each conduit

Outer diameter

The   ?   is the amount of conduit used in a bend.

Developed length

The bend radius of a conduit bend will be slightly larger than the radius of the object it is being bent around.

True

What is the bend angle of each bend for 90° concentric bends each including 12 bends?

7.5°

Concentric bends all have the same centerpoint, but each has a different radius and therefore a different   ?  .

Developed length

A 90° segmented bend with 12 shots and a developed length of 72 inches will have   ?   between shots.

6”

A 90° segmented bend with 15 shots and a developed length of 60 inches will have   ?   between shots.

4”

A   ?   consists of a series of small bends made at predetermined locations on a length of conduit.
