Linear Acceleration

Question 1
Marks : +2 | -2
Pass Ratio : 100%
The acceleration of a particle at any instant has two components, radial component and tangential component. These two components will be
parallel to each other
perpendicular to each other
inclined at 450
opposite to each other
Explanation:
Both the components will be perpendicular to each other.
Question 2
Marks : +2 | -2
Pass Ratio : 100%
The tangential component of acceleration of the slider with respect to the coincident point on the link is called coriolis component of acceleration.
True
False
Explanation:
When a point on one link is sliding along another rotating link, such as in quick return motion mechanism, then the coriolis component of the acceleration must be calculated.
Question 3
Marks : +2 | -2
Pass Ratio : 100%
The coriolis component of acceleration is taken into account for
slider crank mechanism
four bar chain mechanism
quick return motion mechanism
all of the mentioned
Explanation:
When a point on one link is sliding along another rotating link, such as in quick return motion mechanism, then the coriolis component of the acceleration must be calculated.
Question 4
Marks : +2 | -2
Pass Ratio : 100%
The coriolis component of acceleration acts
along the sliding surface
perpendicular to the sliding surface
at 450 to the sliding surface
parallel to the sliding surface
Explanation:
None
Question 5
Marks : +2 | -2
Pass Ratio : 100%
In a shaper mechanism, the coriolis component of acceleration does not exists.
True
False
Explanation:
In a shaper mechanism, the coriolis component of acceleration exists.
Question 6
Marks : +2 | -2
Pass Ratio : 100%
When a point moves along a straight line, its acceleration will have
radial component only
tangential component only
coriolis component only
radial and tangential components both
Explanation:
The tangential component, is parallel to the velocity of the particle at the given instant.
Question 7
Marks : +2 | -2
Pass Ratio : 100%
The centre of gravity of a coupler link in a four bar mechanism will experience
no acceleration
only linear acceleration
only angular acceleration
both linear and angular acceleration
Explanation:
None
Question 8
Marks : +2 | -2
Pass Ratio : 100%
The coriolis component of acceleration depends upon
velocity of slider
angular velocity of the link
all of the mentioned
none of the mentioned
Explanation:
None
Question 9
Marks : +2 | -2
Pass Ratio : 100%
When a point at the end of a link moves with constant angular velocity, its acceleration will have
radial component only
tangential component only
coriolis component only
radial and tangential components both
Explanation:
The centripetal or radial component, is perpendicular to the velocity of the particle at the given instant.
Question 10
Marks : +2 | -2
Pass Ratio : 100%
A body in motion will be subjected to coriolis acceleration when that body is
in plane rotation with variable velocity
in plane translation with variable velocity
in plane motion which is a resultant of plane translation and rotation
restrained to rotate while sliding over another body
Explanation:
When a point on one link is sliding along another rotating link, such as in quick return motion mechanism, then the coriolis component of the acceleration must be calculated.
