Test: Power Screws & Self Locking Screws - Question 1

### A power screw is only used to convert rotary motion into linear motion and not for transmitting power.

Detailed Solution for Test: Power Screws & Self Locking Screws - Question 1

Explanation: Power screw converts the motion from rotary to linear and is used for power transmission.

Test: Power Screws & Self Locking Screws - Question 2

### Depending upon the holding arrangement, power screws operate in how many different arrangements.

Detailed Solution for Test: Power Screws & Self Locking Screws - Question 2

Explanation: There are two types of arrangements. In one screw rotates while nut remains stationary and vice versa.

Test: Power Screws & Self Locking Screws - Question 3

### V threads are highly recommended for fastening as well as power transmission purpose.

Detailed Solution for Test: Power Screws & Self Locking Screws - Question 3

Explanation: In fastening, high frictional force is required and hence V threads are used whereas in power transmission, reduction in frictional forces is required.

Test: Power Screws & Self Locking Screws - Question 4

A power screw has no problem of wear as there is very less amount of friction associated.

Detailed Solution for Test: Power Screws & Self Locking Screws - Question 4

Explanation: Wear is a serious problem in power screws as there is high friction in threads.

Test: Power Screws & Self Locking Screws - Question 5

Trapezoidal threads are better than square threads as there is radial pressure or side thrust on the nut.

Detailed Solution for Test: Power Screws & Self Locking Screws - Question 5

Explanation: Trapezoidal and not square threads suffer from the problem of bursting.

Test: Power Screws & Self Locking Screws - Question 6

Detailed Solution for Test: Power Screws & Self Locking Screws - Question 6

Explanation: Square threads have less thickness at the core diameter and hence lower load carrying capacity.

Test: Power Screws & Self Locking Screws - Question 7

Which of the following are true for buttress threads?

Detailed Solution for Test: Power Screws & Self Locking Screws - Question 7

Explanation: As force is applied only in one direction in a vice so buttress threads are used.

Test: Power Screws & Self Locking Screws - Question 8

Tr 40 x 14(P 7), here 14 indicates

Detailed Solution for Test: Power Screws & Self Locking Screws - Question 8

Test: Power Screws & Self Locking Screws - Question 9

If nominal diameter of screw thread=50mm and pitch=10mm then the mean diameter of the screw thread will be?

Detailed Solution for Test: Power Screws & Self Locking Screws - Question 9

Explanation: Diameter(mean)=Diameter(nominal) – 0.5P .

Test: Power Screws & Self Locking Screws - Question 10

If the load itself begin to the screw and descend down, unless a restraining torque is applied then the condition is termed as

Detailed Solution for Test: Power Screws & Self Locking Screws - Question 10

Explanation: Overhaulting is the condition when load itsel begin to turn the screw.
