In a Kinematic chain, a quarternary joint is equivalent to

Detailed Solution: Question 1

- A quarternary joint connects four links in a kinematic chain.
- It can be broken down into simpler binary joints, which connect only two links each.
- Each quarternary joint is equivalent to three binary joints because it effectively creates three connections.
- Thus, the correct answer is that one quarternary joint is equivalent to three binary joints, making option 3 the right choice.

Degree of freedom
f = 3 (N - 1) - 2p1
where
N = number of links
p1 = number of revolute pair
Given, N = 5 , p1 = 5

Save

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: 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
Save

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: 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.
