A planar four-bar linkage mechanism with 3 revolute kinematic pairs and 1 prismatic kinematic pair is shown in the figure, where AB ⊥ CE and FD ⊥ CE . The T-shaped link CDEF is constructed such that the slider B can cross the point D, and CE is sufficiently long. For the given lengths as shown, the mechanism is
  • a)
    a Grashof chain with links AG, AB, and CDEF completely rotatable about the ground link FG
  • b)
    a non-Grashof chain with all oscillating links
  • c)
    a Grashof chain with AB completely rotatable about the ground link FG, and oscillatory links AG and CDEF
  • d)
    on the border of Grashof and non-Grashof chains with uncertain configuration(s)
Correct answer is option 'A'. Can you explain this answer?

Link (1) = 3 cm → shortest 
Link (2) = 5 cm
Link (3) = 3 cm + Lx → Longest
Link (4) = 1.5 cm + Lx
S + l ≤ p + q
3 + 3 = Lx ≤ 5 + 1.5 + Lx
6 ≤ 6.5
Law satisfied and shortest link is fixed → Double crank
Hence, the correct option is (A).
