Question

Which mechanism is formed by the inclusion of ternary or higher order floating link to a simple mechanism?
1. Compound mechanism
2. Complex mechanism
3. Planar mechanism
4. Spatial mechanism

Answer 1

Correct Answer - Option 2 : Complex mechanism

Explanation:

• A mechanism is a set of machine elements or components or parts arranged in a specific order to produce a specified motion.
• When one of the links of a kinematic chain is fixed, the chain is called a mechanism.
• Mechanism s are of the following types:
• Simple mechanism
  • This is a mechanism which has four links
• Compound mechanism
  • This is a mechanism which has more than four links
• Complex mechanism
  • This is formed by the inclusion of ternary or higher-order floating link to a simple mechanism
• Planar mechanism
  • This is formed when all the links of the mechanism lie in the same plane
• Spatial mechanism
  • This is formed when all the links of the mechanism lie in the different plane
• Equivalent mechanism
  • Turning pairs of plane mechanisms may be replaced by other types of pairs such as sliding pairs or cam pairs.
  • The new mechanism thus obtained having the same number of degrees of freedom as the original mechanism is called the equivalent mechanism
