In gears, interference takes place when

In gears, interference takes place when Correct Answer the tip of a tooth of a mating gear digs into the portion between base and root circles

Interference occurs when the number of teeth on the smaller of the two meshing gears is less than a required minimum.

Consider the following modifications regarding avoiding the interference between gears: 1. The centre distance between meshing gears be increased 2. Addendum of the gear be modified 3. Teeth should be undercut slightly at the root 4. Pressure angle should be increased 5. Circular pitch be increased Which of these are effective in avoiding interference?
Consider the following statements: 1. In spur gears, the contact occurs abruptly on a line parallel to the axis, and the disengagement too is abrupt. 2. In helical gears, both loading and unloading are gradual, and therefore, these happen more smoothly and less noisily 3. When two gears mesh, any arbitrary shape of the tooth can be chosen for the profile of the teeth of any one of the two gears, and the profile for the other shall be obtained by applying the law of gearing. Which of the above statements are correct?

The digit at unit's place is half of the digit at hundred's place. Digit at Ten thousand's place is sum of the digits at thousands and hundreds place and digit at lakh's place is half the digit at ten thousands place. What will be the number?
Interference in a pair of gears is avoided, if the addendum circles of both the gears intersect common tangent to the base circles within the points of tangency.
Statement (I): Two  non-intersecting and non-parallel, i.e., non-coplanar, shafts connected by gears are called skew-bevel gears or spiral gears, and this type of gearing has a line contact the rotation of which about the axes generates the two hyperboloid pitch surfaces. Statement (II): A hyperboloid is a 3D surface formed by revolving a straight line about an axis (not in the same plane), such that every point on the line remains at a constant distance from the axis.
Consider the following statements: In case of helical gears, teeth are cut at an angle to the axis of rotation of the gears. 1) Helix angle introduces another ratio called axial contact ratio. 2) Transverse contact ratio is equal to axial contact ratio in helical gears. 3) Large transverse contact ratio does not allow multiple teeth to share the load. 4) Large axial contact ratio will cause larger axial force component Which of the above statements are correct?
