which type of gears has point contact between two mating gears?

A helical gears
B spiral gears
C both (a) and (b)
D none of these

Correct Answer: spiral gears

In case of spur gears, the contact between tooth profiles is line contact, and in case of helical gears the contact is point contact. So answer is Helical Gear (A).

Two circular dials of exactly the same size are mounted on a wall side by side in such a way that their perimeters touch at one point. Dial 1, which is on the left , spins clockwise around its center , and dial 2 , which is on the right spins counter clockwise around its center . (Assume that there is no friction at the point of contact between the dials.) Each dial is marked on its perimeter at three points that are at equale distances around the points arked ondial 1 are N, O, and P and the points marked on dial 2 are X, Y, and Z. If points O and Z are just meeting at the point of contact between the dials , and if dial 1 spins at the same speed as dial 2, what is the smallest number of revolutions of each dial that will bring O and Z together again?
A 1
B 2
C 3
D 4

A An inherited condition can cause both weak eyesight and dry eyes
B Physical exertion causes dry eyes in many people who wear contact lenses.
C Most people who have dry eyes do not wear contact lenses.
