100

What is the side opposite the right angle in a right triangle?

Hypotenuse

100

What is the term for the deduct amount in 90-degree bends?

Take-up

100

The mark on the conduit bender that is aligned with the marks for 90s and offsets?

The Arrow

200

What is the marking system on Greenlee hand benders that aids in determining bend angles?

SiteRite

200

What is another name for Electrical Metallic Tubing (EMT)?

Thinwall

200

What line just touches a curve at one point without cutting across it? 

Tangent

200

What is another term for back-to-back 90-degree bends that mirror each other? 

U bend

200

What is the term used to compensate for conduit appearing to shrink in length due to bends?

shrink factor or shrink amount

300

What is the area at the front end of the bender’s shoe groove that is subject to the forces required to bend the conduit? 

Hook

300

What conduit is slightly lighter than Rigid (RMC) due to a thinner wall but uses the same threads? 

Intermediate Metallic Conduit (IMC)

300

What trigonometric function is equal to the Opposite over the Hypotenuse? (hint: think sine, cosine, cosecant, etc.)

Sine

300

What bend consists of two equal angle bends made 180 degrees opposite each other?

Offset

300

What is the marking on the Greenlee hand bender used for the center bend of a 3 bend saddle?

The Notch

400

What is the amount (measured in degrees) that a bent pipe tends to straighten after pressure is released? 

Springback

400

What type of conduit is made from polyvinylchloride and typically gray in color?

PVC (PolyVinylChloride)
400

What is the inverse of Cosine?

Secant

400

What is a bend consisting of 3 or 4 bends that moves the path of the conduit parallel to the original path?

Saddle Bend

400
When bending conduit, how should the bottom of the tubing align with the degree marks on the bender?

Parrallel

500

What is the portion of a bender that the conduit is pressed against to form a bend of a specific radius? 

Shoe

500

What type of conduit has a 40 MIL thick PVC coating bonded to the outer wall? 

PVC-Coated Rigid

500

Which trigonometric function can be used to find the center to center distance of an offset? (hint: think sine, cosine, secant, etc.)

Cosecant

500

What is a bend formed by a series of smaller degree bends rather than a single one-shot bend?

Segment Bend

500
To find the measurements for this bend, 3/16" must be accounted for shrink amount per 1 inch of rise of the obstacle, and the outer markings must be calculated at 2 1/2" per inch of rise of the obstacle.
