Question

Degrees of freedom for the kinematic chain with 3 revolute pairs and one sliding pair as shown in figure is

• A. 1
• B. 2
• C. 3
• D. 4

Answer 1

The correct option is A 1

There are only three revolute pairs and one sliding pair. Slider slides on link-1.


$F=3(N-1)-2j-h$

$F=3(4-1)-2\times 4-0$

$F=1$
