Final answer:
The grip length of the aircraft bolt is calculated by subtracting the threaded portion (5/8 inch) from the shank length (1-3/16 inches), resulting in a grip length of 9/16 inches.
Step-by-step explanation:
To find the grip length of the aircraft bolt, we must subtract the length of the threaded portion from the shank length. The bolt has an overall length of 1-1/2 inches, a shank length of 1-3/16 inches, and a threaded portion length of 5/8 inch. Using these measurements, we calculate the grip length as follows:
1-3/16 inches (shank length) - 5/8 inch (threaded portion) = 19/16 inches - 5/8 inches
To subtract these fractions, we need a common denominator, which is 16. Therefore, we convert 5/8 to 10/16:
19/16 inches - 10/16 inches = 9/16 inches
Thus, the grip length of the bolt is 9/16 inches.
