Find the mobility DoF and Grashof condition of the mechanism

Find the mobility (DoF) and Grashof condition of the mechanism below. Also, which inversion is it?

Mobility

n = 4

p = 4

DOF = 3*(n-1) - 2*p = 3*3 - 2*4 = 1

Grashof\'s Condition:

s + l = 0.68+1.62 = 2.3 in

p + q = 1.38 + 1.22 = 2.6

as (s+l)<(p+q) so it is Grashof linkage.

As the shortest part is the Frame (BasePart), so the linkage is a Double-Crank (or drag link) mechanism.
