Test: Bolts Of Uniform Strength & Locking Devices - Question 1

Resilience is defined as the property of material to absorb energy when deformed _________ and to release this energy when unloaded.

Detailed Solution for Test: Bolts Of Uniform Strength & Locking Devices - Question 1

Explanation: It is the definition of resilience.

Test: Bolts Of Uniform Strength & Locking Devices - Question 2

The shock absorbing capacity of bolt can be increased by making the shank diameter ________ the root diameter.

Detailed Solution for Test: Bolts Of Uniform Strength & Locking Devices - Question 2

Explanation: If shank diameter is equal to the thread diameter than, the shank is subjected to higher stress and thus absorbs a great portion of strain energy and relieves the thread portion of high stress.

Test: Bolts Of Uniform Strength & Locking Devices - Question 3

The shock absorbing capacity of bolts can be increased by

Detailed Solution for Test: Bolts Of Uniform Strength & Locking Devices - Question 3

Explanation: Shock absorbing capacity can be increased by decreasing the shank diameter or increasing the length of shank.

Test: Bolts Of Uniform Strength & Locking Devices - Question 4

If the length of the shank is doubled, then strain energy absorbed by shank

Detailed Solution for Test: Bolts Of Uniform Strength & Locking Devices - Question 4

Explanation: Strain energy absorbed by shank is linearly proportional to its length.

Test: Bolts Of Uniform Strength & Locking Devices - Question 5

Which of the following help in accomplishing the locking?

Detailed Solution for Test: Bolts Of Uniform Strength & Locking Devices - Question 5

Explanation: All the methods can be employed to lock the screw.

Test: Bolts Of Uniform Strength & Locking Devices - Question 6

Crests and roots of the threads may lead to leakage in fluid tight threads if flattened or rounded to a circular arc.

Detailed Solution for Test: Bolts Of Uniform Strength & Locking Devices - Question 6

Explanation: As there is engagement in the threads, chances of leakage are reduced.

Test: Bolts Of Uniform Strength & Locking Devices - Question 7

The static load carrying capacity of fine threads is greater than that of coarse threads.

Detailed Solution for Test: Bolts Of Uniform Strength & Locking Devices - Question 7

Explanation: Coarse threads have a higher load carrying capacity.

Test: Bolts Of Uniform Strength & Locking Devices - Question 8

Coarse threads have helix angle _____ fine threads.

Detailed Solution for Test: Bolts Of Uniform Strength & Locking Devices - Question 8

Explanation: Finer threads have lower helix angle.

Test: Bolts Of Uniform Strength & Locking Devices - Question 9

 Which threads have greater resistance to unscrewing?

Detailed Solution for Test: Bolts Of Uniform Strength & Locking Devices - Question 9

Explanation: Fine threads have greater resistance to unscrewing as a result of lower helix angle.

Test: Bolts Of Uniform Strength & Locking Devices - Question 10

Which type of threads is recommended for fluctuating loads?

Detailed Solution for Test: Bolts Of Uniform Strength & Locking Devices - Question 10

Explanation: Fine threads have lesser helix angle and hence greater resistance for unscrewing and thus are recommended for fluctuating loads.
