Question
A four bar mechanism is made up of links of length 100,200,300 and 350 mm. if the 350 mm link is fixed, the number of links that can rotate fully is ______
Answer :
1
s = 100, p = 200,l = 350, q = 300
(s +l) = 350 + 100 = 450 <(p+ q)
450 < 200 + 300
450< 500
Grashoff’s law is satisfied.
350 mm link is fixed,
Then, shortest link = 100 mm s adjacent to fixed, will give crank only.
