How can shock absorbing capacity of a bolt be increased?a) By tighten...
Increasing the shock absorbing capacity of a bolt can be achieved by making the shank diameter equal to the core diameter of the thread. This means that the diameter of the shank should match the inner diameter of the threaded portion of the bolt. Here's an explanation of why this is the correct answer:
The shock absorbing capacity of a bolt is directly related to its ability to withstand external forces and resist deformation. When a bolt is subjected to shock or impact loads, it experiences stress and strain. If the bolt is unable to absorb and distribute these forces effectively, it may fail or become permanently deformed.
By making the shank diameter equal to the core diameter of the thread, the bolt is strengthened in two ways:
1. Increased cross-sectional area: The shank of the bolt is the portion between the head and the threaded portion. By increasing the diameter of the shank, the cross-sectional area of the bolt is increased. This increased area provides more material to resist the external forces and distribute them evenly along the length of the bolt.
2. Enhanced load distribution: When the shank diameter matches the core diameter of the thread, the load is distributed more evenly between the shank and the threaded portion. This prevents localized stress concentrations that can occur when there is a significant difference in diameter between the shank and the thread. By distributing the load more evenly, the bolt is better able to absorb and dissipate the shock or impact forces.
In addition to the above advantages, making the shank diameter equal to the core diameter of the thread also ensures a better fit between the bolt and the threaded hole. This improves the overall stability and strength of the joint.
Overall, by increasing the shank diameter to match the core diameter of the thread, the shock absorbing capacity of the bolt is significantly increased. This allows the bolt to withstand higher levels of shock and impact loads without failure or deformation.
