Question:-
For the configuration shown, the angular velocity of link AB is 10 rad/s counterclockwise.
The magnitude of the relative sliding velocity (in ms-1) of slider B with respect to rigid link CD is

Option (A)
0
Option (B)
0.86
Option(C)
1.25
Option(D)
2.5
Correct Option:
(D)
Question Solution:
wAB = 10rad/sec CCw VB/C =?



AB=250mm BC=250 Ö3mm AC=500 mm

The direction of relative velocity of slider B with respect to ‘C’ is inline with the link BC. The direction
of velocity of ‘AB’ is ar ^ to link ‘AB’ and parallel to the link CD

\ Vc=0,
\ VB/c = VB - Vc = 2.5 – 0 = 2.5m/sec

VB = rABxwAB = 250x10 = 2500 Þ 2.5m/sec.

Vc = 0
