Question
A slider moves with uniform velocity v on a revolving link of length r with angular velocity w. The Coriolis acceleration component of a point on the slider relative to a coincident point on the link is equal to  
एक स्लाइडर एकसमान वेग v के साथ कोणीय वेग w के साथ लंबाई r की एक घूमती हुई कड़ी पर घूमता है। लिंक पर एक संयोग बिंदु के सापेक्ष स्लाइडर पर एक बिंदु का कोरिओलिस त्वरण घटक बराबर है
A.
ων parallel to the link 
B.
2ων perpendicular to the link 
C.
ων perpendicular to the link 
D.
2ων parallel to the link
Answer ( Option B)

2ων perpendicular to the link 

Solution

Coriolis component of acceleration: 
  • When a point on one link is sliding along another rotating link such as in quick return motion mechanism, then the Coriolis component of acceleration comes into account.
  • It is the tangential component of the acceleration of the slider with respect to the coincident point on the link. 
&Key Points :-
  • Mathematically, Coriolis component of acceleration, ac = 2νω
  • The direction of the Coriolis component of acceleration is given by rotating the velocity of the slider by 90° in the direction of the angular velocity of the rotating link.
