Question 643General Subjects - Assistant Engineer
70% to passTo obtain a 1/2 inch per foot taper on an 18 inch work piece, the tailstock of the lathe must be set over _______________.
A3/8 inch
B1/2 inch
C3/4 inch
D7/8 inch
AI Explanation
The correct answer is A) 3/8 inch. To obtain a 1/2 inch per foot taper on an 18 inch work piece, the tailstock of the lathe must be set over 3/8 inch. This is calculated by taking the desired taper of 1/2 inch per foot and multiplying it by the length of the work piece (18 inches), then dividing the result by 12 inches per foot to get the required tailstock offset. The other options are incorrect because they do not match the calculated offset of 3/8 inch needed to achieve the desired 1/2 inch per foot taper on an 18 inch work piece.
