Test: Mechanism With Lower Pairs - 1 - Question 5

The Davis steering gear is not used because

Detailed Solution for Test: Mechanism With Lower Pairs - 1 - Question 5

A Davis steering gear has sliding pairs which means more friction and easy wearing. The gear fulfills the fundamental equation of gearing in all the positions. Due to easy wearing if becomes inaccurate after some time.

Test: Mechanism With Lower Pairs - 1 - Question 6

The Davis steering gear fullfills the condition of correct gearing at

Test: Mechanism With Lower Pairs - 1 - Question 7

The Ackermann steering gear fulfills the condition of correct gearing at

Detailed Solution for Test: Mechanism With Lower Pairs - 1 - Question 7

An Ackermann steering gears has only turning pairs and thus is preferred. Its drawback is that fulfills the fundamental equation of correct gearing at the middle and the two extreme positions and not in all positions.

Test: Mechanism With Lower Pairs - 1 - Question 8

The ratio between the width of the front axle and that of the wheel base of a steering mechanism is 0.44. At the instant when the front inner wheel is turned by 18°, what should be the angle turned by the outer front wheel for perfect steering?
[Take cot18° = 3.078, cot16° = 3.487, cot20° = 2.747]

Detailed Solution for Test: Mechanism With Lower Pairs - 1 - Question 8


∴  

From the given data, we can see that φ should be closer to 16° and best possible option is (a).
