The taper is given as a ratio, which can be simplified to 0.029:1. To find the taper for a 4 inch long pin, we multiply the length of the pin by the ratio:

4 x 0.029 = 0.116 inches

However, the question asks for the taper, not the total amount of taper on a 4 inch pin. To find the taper per inch, we divide the total taper by the length of the pin:

0.116 / 4 = 0.029 inches per inch, or 0.029:1

So the answer is B, 0.12 inches.

The Taper of a Pin Is 0
