Question 30

1 9/16 inches

The maximum size hole that can be bored for a 3/4-inch pipe in a 2" x 6" wood exterior load-bearing wall stud is 1 9/16 inches. This size ensures that the structural integrity of the stud is maintained while allowing for the necessary pipe installation.

A) 1 3/8 inches

While 1 3/8 inches is a reasonable size for a hole, it is not the maximum size permitted for a 3/4-inch pipe in this context. Boring a hole of this size may unnecessarily restrict the pipe's passage, while still being compliant with certain codes, it does not utilize the maximum allowable limit.

B) 1 9/16 inches

This is the correct answer because it represents the maximum size hole that can be bored in a 2" x 6" wood stud for a 3/4-inch pipe. This size hole provides adequate clearance while maintaining the structural integrity of the wall stud, as specified by building codes.

C) 2 3/16 inches

A hole size of 2 3/16 inches exceeds the maximum allowable limit for a 3/4-inch pipe in a load-bearing wall stud. Such a large hole would compromise the structural strength of the stud, potentially leading to safety hazards.

D) 3 1/4 inches

This option is not viable as it significantly surpasses the maximum allowable hole size. A hole of this diameter would severely weaken the load-bearing capacity of the stud, contravening safety regulations and building codes.

Conclusion

The maximum allowable hole size for a 3/4-inch pipe in a 2" x 6" wall stud is definitively 1 9/16 inches, which balances functional needs with structural safety. All other options either fall short of this maximum or exceed safe drilling limits, thereby failing to meet the requirements for load-bearing structures.
