 What type of friction in cup design is recommended for the set screw?
Detailed Solution for Test: Screw Jack - Question 4

Explanation: Sliding friction, the total force require to raise the load is quite large as compared to that required in rolling friction. Hence length of handle in some cases becomes extremely large and thus it is impractical to use cups with sliding friction.

Test: Screw Jack - Question 5

A differential screw is defined as a mechanical device consisting of two screws connected in parallel.
Detailed Solution for Test: Screw Jack - Question 5

Explanation: The two screws are connected in series.

Test: Screw Jack - Question 6
Save

 In a differential screw, two screws are connected in series such that the resultant motion is the summation of the motion of the two screws.
Detailed Solution for Test: Screw Jack - Question 6

Explanation: The resultant motion is the difference of the individual motion of two screws.

Test: Screw Jack - Question 7
Save

 A compound screw consist of two screws in parallel such that the resultant motion is the summation of the individual motion of screws.
Detailed Solution for Test: Screw Jack - Question 7

Explanation: The two screws are connected in series with the resultant motion being the sum of individual motion.

Test: Screw Jack - Question 8
Save

What is the output from differential screws when pitch of the two screws is 12mm and 8mm? Also the nut is rotated by applying a force of 120N at a radius of 300mm and the two screws remain stationary. The torque of raising and lowering for the two screws is 5k N-mm and 2.5k N-mm where k is the effective axial weight on the screw.
Detailed Solution for Test: Screw Jack - Question 8

Explanation: 120 x 300=5k+2.5k or k=4800N. Output=k x (12-8) or output=19200N-mm.

Test: Screw Jack - Question 9
Save

What is the efficiency of differential screws when pitch of the two screws is 12mm and 8mm? The nut is rotated by applying a force of 120N at a radius of 300mm and the two screws remain stationary. The torque of raising and lowering for the two screws is 5k N-mm and 2.5k N-mm where k is the effective axial weight on the screw.
Detailed Solution for Test: Screw Jack - Question 9

Explanation: 120 x 300=5k+2.5k or k=4800N. Output=k x (12-8) or output=19200N-mm. Efficiency=output/2πx120x300.

Test: Screw Jack - Question 10
Save

 In which case is the wear more?
Detailed Solution for Test: Screw Jack - Question 10

Explanation: In recirculating ball screw, there is a lubricant film between the contacting surfaces and hence lesser wear.
