Question

In a four bar mechanism, the dimensions of the links are as given below:
AB = 50 mm, BC = 66 mm
CD = 56 mm and AD = 100 mm
At a given instant when | DAB=60°
the angular velocity of link AB is 10.5
rad/sec in CCW direction.Determine,
i) Velocity of point C
ii) Velocity of point E on link BC when BE = 40 mm
iii) The angular velocity of link BC and CD
iv) The velocity of an offset point F on link BC, if BF = 45 mm,
CF = 30 mm and BCF is read clockwise.
v) The velocity of an offset point G on link CD, if CG = 24
mm, DG = 44 mm and DCG is read clockwise.
vi) The velocity of rubbing of pins A, B, C and D. The ratios of
the pins are 30 mm, 40 mm, 25 mm and 35 mm
respectively.
