To transmit power from one rotating shaft to another whose axes are neither parallel nor intersecting, use 

To transmit power from one rotating shaft to another whose axes are neither parallel nor intersecting, use  Correct Answer Worm Gear

Explanation:

Spur gears

  • Spur gears are used to connect two shafts when they are transmitting the power in a parallel direction.
  • In spur gears when the teeth start getting engaged the contact between the teeth extends across the entire width on a line parallel to the axis of the rotation this results in the sudden application of the load, high impact stresses.
  • It is used to transmit low power.

Bevel Gear: 

  • Bevel gears are used to transmit motion between shafts at various angles to each other, thus they are non-parallel but intersecting. 
  • The teeth profile may be straight or spiral.

Worm Gear: 

It is essentially a form of spiral gearing in which the shafts are usually at right angles. 

The two non-parallel and non-intersecting, but non-coplanar shafts are connected by worm gears.

Spiral Gear:

The motion between two intersecting shafts is equivalent to the rolling of two cones, assuming no slipping. The gears are in general known as bevel gears.

When teeth formed on the cones are straight, the gears are known as straight bevel gears and when they are inclined they are known as spiral bevel gear.

 

In helical gears, the power is transmitted between two parallel shafts. In spiral gears (cross-helical gears) the power is transmitted between two non-parallel and non-intersecting shafts.

Helical gears give a point contact. Due to point contact, spiral gears are not recommended for power transmission.

Spiral gears are used in instrumentation, distribution devices of automobile engines and other similar applications where there are small loads.

Each item consists of six sentences of a passage. The first and sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled as P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly on the Answer Sheet. S1 : He no longer dreamed of storms, nor of women, nor of great occurrences, nor of great fish, nor fights, nor contests of strength, nor of his wife.

S6 : He urinated outside the shack and then went up the road to wake the boy.

P : He never dreamed about the boy.

Q : He only dreamed of places and of the lions on the beach now.

R : He simply woke, looked out through the open door at the moon and unrolled his trousers and put them on.

S : They played like young cats in the dusk and he loved them as he loved the boy.

The correct sequence should be
P, Q, R, S, T, W, Y and Z are sitting around a circular table from equal distances to each other and facing towards centre. They all like different colours viz., Red, Blue, Green, Black, White, Pink, Yellow and Brown (not necessarily in the same order). P likes yellow and sitting third to the left of W. Two persons are sitting between W and S. The one who likes pink is not sitting with P nor with W. Only one person is sitting between T and Z but not P and S. Y likes black but he is not sitting with S. R does not like pink nor white. T is sitting to the immediate left one who likes green. Z does not like brown nor he is sitting to the immediate right one who likes black. The one who likes white is not sitting with W. R neither likes brown nor Red. Which of the following combination is true as per the given information?
