Two separate work pieces are to have a taper cut with the same taper per inch, using the offset tailstock method. After the first piece is completed, the tailstock offset must be changed if there is a change in the _______________.

Adiameter of the work piece
Bangle of the cutting tool
Clength of the work piece
Dnone of the above
AI Explanation

The correct answer is C) length of the work piece. When using the offset tailstock method to cut a taper, the tailstock offset needs to be changed if there is a change in the length of the work piece. This is because the amount of taper per inch is determined by the ratio between the tailstock offset and the length of the work piece. If the length of the work piece changes, the tailstock offset must be adjusted to maintain the same taper per inch, even if the diameter of the work piece or the angle of the cutting tool remain the same. The other options (A and B) do not require a change in the tailstock offset, as the taper per inch is not affected by changes in the diameter of the work piece or the angle of the cutting tool.
