| 31. | Argon is the most commonly used shielding gas for GTAW, since it helps prevent defects due to a varying arc length.
|
| 32. | The ratio of the arc length to the outer cut radius will give you the angle of your pie slice in radians.
|
| 33. | The determination of the arc length of arcs of the lemniscate leads to elliptic integrals, as was discovered in the eighteenth century.
|
| 34. | Comes from the Pythagorean theorem and represents a small segment of the arc of the curve, as in the arc length formula.
|
| 35. | In terms of four-dimensional spacetime, proper time is analogous to arc length in three-dimensional ( Euclidean ) space.
|
| 36. | If we were using different angle units, and not radians, then the formula for the arc length would have been different.
|
| 37. | For example, the arc length of a segment of an ellipse can be determined using an incomplete elliptic integral of the second kind.
|
| 38. | By definition, the arc length of a curve is the least upper bound of the lengths of all polygonal approximations of the curve.

|
| 40. | A significant disadvantage is the difficulty of striking an arc with helium gas, and the decreased weld quality associated with a varying arc length.
