Great video for a refresher

[@Dagoooo16]

Very helpful! Thank you

[@SamyyCJR]

Developed length is RadiusX1.57

[@jacobyben6349]

Great video but how did you get your radius

[@user-ki4wz2ic7h]

Yea! Work of art.

[@manuelsouto8295]

Yes. Developed length is 1.57xR and will be the distance between first and last kick. Then in order to deal with the bender shoe he makes total segments length aprox 10% longer.
1.57xRx1.10=1.73xR, rounded up to 1.75xR. Got answer?

How did you find your radius

[@aaronh7804]

Google how to find the radius of a circle using the chord length and arc height. Vcalc has a calculator and the formula.

[@SapphireJewels24]

@val3077 no disrespect to the man recording the video but he's wrong. It's radius x 1.57. Pie divided by 2 is what we are looking for. My husband has a conduit bending channel @artofconduitbending . On another note to find radius of a 90 is easy I'm sure if you go to that channel he'll show you.

How did you find the radius

[@sparkythetraveler]

Radius ×1.57÷ degree of bend

[@alq8879]

1.57 instead of 1.75

[@rickjljr11]

Yup or pi/2. Circle Arc Length with the Radius and Central Angle = Angle * Radius (where the angle is in radians). radians = angle(deg) / 360 *2*pi

[@OdinJB]

Half of pi isn’t 1.75 . Half of pie is 1.57
