Degree of freedom
f = 3 (N - 1) - 2p1
where
N = number of links

Test: Simple Mechanisms - 3 - Question 18

In a four-bar linkage, the sum of the lengths of the smallest and the longest link is less than the sum of the lengths of the other two links. If the smallest link is fixed, the linkage becomes a

For a four bar mechanism If S + L ≤ Sum of other two and if smallest link is fixed then crank-crank mechanism can be obtained.

Test: Simple Mechanisms - 3 - Question 19

The input link, coupler link and the fixed link of a four bar mechanism have lengths 500 mm, 600 mm and 300 mm, respectively. When the input link is rotated by a motor, the output link can make complete revolutions if its length ‘L in mm satisfied the condition

Detailed Solution for Test: Simple Mechanisms - 3 - Question 19

For complete revolution of output link
Shortest link + Largest < Sum of other two link

If coupler is longest link, then
600 + 300 ≤ L + 500 
L ≤ 400
If output is longest link, then
300 + L ≤ 600 + 500
L ≤ 800
Hence 400 < L < 800

Test: Simple Mechanisms - 3 - Question 25

The four bar mechanism shown in the figure (Given : OA = 3 cm, AB = 5 cm, BC = 6 cm, OC = 7 cm) is a

Detailed Solution for Test: Simple Mechanisms - 3 - Question 25

OC = 7 cm (longest link)

OA = 3 cm (shortest link)

AB = 5 cm and BC = 6 cm

OA + OC = 7 + 3 = 10 cm

AB + BC = 11 cm

Since OA + OC < AB + BC

i.e. the sum of shortest and longest link is less than the sum of other two links. Thus, the given links form a Grashoff chain.

According to Grashoff law:

(i) The double crank mechanism is obtained if the shortest link is fixed.

(ii) Crank – rocker mechanism is obtained if link adjacent to shortest link, is fixed.

(iii) Double rocker mechanism is obtained if link opposite to shortest link, is fixed.

Here the link adjacent to the shortest link is fixed. Thus, the mechanism is a crank-rocker mechanism.
