Answer:


L_1>32 cm

Step-by-step explanation:

Given that


L_2=27 cm


L_3=5 cm


L_4=10 cm

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


L_3+L_1>L_2+L_4

Now put the values


5+L_1>27+10


L_1>32 cm

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