In a bolt of uniform strengtha)There are many free threads under the n...
In normal situations, where bolts are subjected to shock or impact loads,the stress in the threaded part of the bolt will be higher than that in the shank. Hence a great portion of the energy will be absorbed at the region of the threaded part which may fracture the threaded portion because of its small length.
If the shank of the bolt is turned down to a diameter equal or even slightly less than the core diameter of the thread then shank of the bolt will undergo a higher stress. This means that a shank will absorb a large portion of the energy, thus relieving the material at the sections near the thread. The bolt, in this way, becomes stronger and lighter and it increases the shock absorbing capacity of the bolt because of an increased modulus of resilience. This gives us bolts of uniform strength.
Bolt of Uniform Strength with Reduced Shank Diameter
A second alternative method of obtaining the bolts of uniform strength is to drill an axial hole through the head as far as the thread portion such that the area of the shank becomes equal to the root area of the thread.

Explanation:
Shank turned down to a diameter equal to the diameter of the root of threads:
- In a bolt of uniform strength, the shank is turned down to a diameter that is equal to the diameter of the root of the threads.
- This ensures that there is no sudden change in diameter, which could lead to stress concentration and potential failure points.
- By matching the shank diameter to the root diameter of the threads, the stress distribution along the bolt is more uniform, enhancing its strength.
Therefore, among the options given, the correct one is:
c) The shank is turned down to a diameter equal to the diameter of the root of threads
