Question:-
In a slider-bar mechanism, when does the connecting rod have zero angular velocity?
Option (A)
When crank angle = 0°
Option (B)
When crank angle = 90°
Option(C)
When crank angle = 45°
Option(D)
Never
Correct Option:
(B)
Question Solution:
wcr = [wcos q / Ö(n2 - sin2 q)]
Angular velocity is maximum at q = 0, 180°
Angular velocity is zero at q = 90°
