Answer:
The nail penetrates into the frame by 1.875 inches
Explanation:
For an 8d nail, it has a length of 2.5 inches, a diameter of 0.13 inches and a head diameter of 0.28125 inches. 8d nails in buildings are used in attaching studs to wall plate, rafter to top wall plates. It is also used when you need to drive a nail at an angle into a wood member.
Since the depth of an 8d nail is 2.5 inches and the sheathing is nailed on the wood frame, to get how far the point of the nail penetrate into the frame, we subtract the depth of the oriented strand board sheathing from the depth of an 8d nail.
Therefore, how far the point of the nail penetrate into the frame = 2.5 inches - 5/8 inches = (2.5 - 0.625) inches = 1.875 inches.
The nail penetrates into the frame by 1.875 inches
