Q1 | Bearing suitable for fluctuating loads is
- Ball bearing
- Needle roller bearing
- Sleeve bearing
- Bush bearing
- Roller bearing
Q2 | Radial distance from the top to the pitch circle for a tooth is known as
- working depth
- dedendum
- addendum
- None of the above
- None of the above
Q3 | Higher pressure angle results in
- Narrow base and weaker teeth
- Weaker teeth
- Non-uniform motion transmission
- Bigger size of gear teeth
- Wider base and stronger teeth
Q4 | In a radial cam with a roller on follwer the prime circle can be defined as
- the smallest circle tangent to the pitch curve
- the smallest circle tangent to the cam profile
- a circle drawn with radius equal to the distance between the pitch point and the centre of base circle
- None of the above
- None of the above
Q5 | Identify the incorrect statement in case of cycloidal gears
- No lubrication needed
- Interference does not exist
- Have less wear
- Interference exists
- Ease in transmitting variable loads
Q6 | Which one of the following is not applicable to involute profile
- The angular velocity ratio when tow involutes are in mesh, is inversely proportional to the size of the base circles
- No involute has a pressure angle until it is brought in contact with other mating involute
- Involute is the only tooth form that is not sensitive to centre distance of their base circles
- The shape of the involute profile is dependent only on the dimensions of the base circle
- The pitch diameters of mating involutes are inversely proportional to their base circle diameters
