Use the Kutzbach Criterion to calculate the mobility and the

Use the Kutzbach Criterion to calculate the mobility and the Grashof Condition for the aircraft overhead bin mechanism shown below. Clearly show the value of n and each j used to calculate the mobility, and the values used to determine the Grashof Condition.

Solution

Number of links ( n ) = 4

Number of lower pairs (j) = 4

Number of higher pairs ( h )= 0

Degrees of freedom ( f ) = 3*(n-1)- 2*j - h

3 * (4-1) - 2*4 = 9 - 8 = 1

Singlinputut parameter is sufficient for mobility.
