In a four bar mechanism, L, is a fixed link; L2 is driver crank; L3 is coupler and L4 is follower crank. L=27 cm, L3 =5 cm and L4=10 mm. Find the length of the link L1 if the linkage can be classified as a double rocker mechanism:

Respuesta :

Answer:

[tex]L_1>32 cm [/tex]

Explanation:

Given that

[tex]L_2=27 cm[/tex]

[tex]L_3=5 cm[/tex]

[tex]L_4=10 cm[/tex]

Here shortest link is link3

To make the linkage as a double rocker mechanism we have to fix longest link that link is link1

So for double rocker mechanism

[tex]L_3+L_1>L_2+L_4[/tex]

Now put the values

[tex]5+L_1>27+10[/tex]

[tex]L_1>32 cm [/tex]

It means that length of link1 should be greater than 32 cm.
