Number of links (𝒍) and the number of
joints (j) for a single degree of freedom kinematic chain with only lower pair
joints, is related by the expression :
केवल लोअर युग्म जोड़ों के साथ एकल डिग्री स्वतंत्रता गतिकी श्रृंखला के लिए लिंकों की संख्या (𝒍) और जोड़ों की संख्या (j) निम्न अभिव्यक्ति द्वारा संबंधित है:
j = 2.5𝒍 - 2
j = 1.5𝒍 - 2
j = 2.5𝒍 - 1
j = 2.5𝒍 - 1
j = 1.5𝒍 - 2
The relation between number of links (𝒍) and the number of joints (j) can be obtained by using Kutzback's equation as:
DOF = 3(𝒍 - 1) - 2j - h
Here, DOF = 1 and h = 0 as degree of freedom is one and there is no higher pair (h).
Hence, the correct option is (B).
