A straight anchor bolt should be installed to a depth of ______ while a bent anchor bolt should have a bent length of ______.

The correct answer states that a straight anchor bolt should be installed to a depth of 25 times its diameter while a bent anchor bolt should have a bent length of 4 times its diameter. This conforms to established engineering practices for ensuring the stability and strength of anchor bolts in various applications.

The 25 times the diameter installation depth for straight anchor bolts generally provides adequate embedment to ensure that the bolt has the necessary resistance against pull-out forces and other loads. This depth helps distribute loads effectively through the concrete or substrate material, significantly enhancing the structural integrity.

For the bent anchor bolt, specifying a bent length of 4 times the diameter ensures that the bend maintains adequate anchorage and load distribution while allowing for necessary clearance and alignment of the bolt. This measurement helps prevent potential points of failure by ensuring that the bent section can bear loads effectively without compromising the bolt's performance.

Overall, these standards are derived from structural engineering principles that take into account the behavior of materials under load, resulting in safer and more reliable installations.
