Question

A crank and rocker mechanism ABCD has the following dimensions: AB =0.75m,
BC =1.25 m, CD =1 m, AD =1.5 m and CF = 500 mm. AD is the fixed link. F lies on BC
produced. Crank AB has an angular velocity of 30 rad/s counter clock-wise and a
deceleration of 200 rad/s2
at the instant angle DAB= 300. Find a) The instantaneous
linear acceleration of C and F b) The instantaneous angular velocities and accelerations
of links BC and CD.

Answer 1

Answer:

mm.E and F are two points on the coupler link BC.AD is the fixed link .BEC is read
