It is planned to construct a four-bar mechanism ABCD with length AB= 60mm, BC = 100mm, CD = 70 mm and fixed link AD = 200 mm. If at least one link is required to have a complete rotation, this mechanism is
(a) of crank-rocker type
(b) of double-crank type
(c) of double rocker type
(d) impossible to construct
This question was addressed to me in a dream while sleeping
My question is based upon Velocities in a Slider Crank Mechanism and Motion of a Link in division Velocity in Mechanisms of Machine Kinematics
