If an aircraft bolt has an overall length of 1-1/2 inches and a shank length of 1-3/16 inches, what is the grip length?

To determine the grip length of the aircraft bolt, you subtract the shank length from the overall length. The formula for grip length is:

Grip Length = Overall Length - Shank Length

In this case, the overall length of the bolt is 1-1/2 inches, which can also be expressed as 1.5 inches when converted to a decimal. The shank length is given as 1-3/16 inches. To work with decimals, first convert 1-3/16 to its decimal form.

1-3/16 can be calculated as follows:

1 inch = 1.0

3/16 inch = 0.1875 (since 3 divided by 16 equals 0.1875)

Therefore, 1-3/16 inches equals:

1.0 + 0.1875 = 1.1875 inches.

Now applying the formula:

Grip Length = 1.5 inches - 1.1875 inches = 0.3125 inches.

Thus the calculation confirms that the grip length is indeed 0.3125 inches which corresponds to the first choice. However, as it stands, the calculation indicates that the answer provided (B) does not match
