Uniform-strength bolts are used for resisting impact loads as these bolts have more strain energy storing capacity.
⇒The area of cross-section of the threaded and unthreaded portion is made equal to increase the strain energy storing capacity.

Assertion (A): Uniform-strength bolts are used for resisting impact loads.
Reason (R): The area of cross-section of the threaded and unthreaded parts is made equal.
The correct answer is option 'B' - both A and R are individually true but R is not the correct explanation of A.
Explanation:
Uniform-strength bolts are designed to have consistent strength throughout their length. They are commonly used in applications where the bolts are subjected to impact loads. These bolts are specifically designed to resist bending or shearing forces caused by sudden impacts.
The area of cross-section of the threaded and unthreaded parts of a uniform-strength bolt is not necessarily made equal. The reason for using a uniform-strength bolt to resist impact loads lies in the design of the bolt itself, rather than the equal cross-section area.
Uniform-strength bolts are often made from high-strength materials such as alloy steel. They are manufactured in a way that ensures the entire length of the bolt has a consistent strength and stiffness. This is achieved by carefully controlling the heat treatment process and the material properties.
The design of the bolt includes considerations such as thread engagement length, thread profile, and shank diameter, all of which contribute to its ability to resist impact loads. The thread engagement length ensures that the bolt can securely fasten the components together, while the thread profile provides optimal load distribution and prevents stress concentrations.
The shank diameter of the bolt is typically larger than the threaded portion to provide additional strength and stiffness. This helps to distribute the impact load over a larger area, reducing the risk of failure.
In summary, uniform-strength bolts are used to resist impact loads due to their consistent strength and stiffness throughout their length. The equal cross-section area of the threaded and unthreaded parts is not the reason for their ability to resist impact loads.
Reason (R): The area of cross-section of the threaded and unthreaded parts is made equal.
The correct answer is option 'B' - both A and R are individually true but R is not the correct explanation of A.
