Question
### Mechanical Advantage of a Mechanism In the diagram, we have a four-bar linkage mechanism configured as shown. This includes links O₂A, AB, O₄B, and the fixed points O₂ and O₄. Below are the given dimensions: - \( O_2O_4 = 120 \, \text{mm} \) - \( O_2A = 60 \, \text{mm} \) - \( AB = 100 \, \text{mm} \) - \( O_4B = 130 \, \text{mm} \) The angle at \( O_2A \) from the horizontal is \( 30^\circ \). **Options for Mechanical Advantage (MA):** - \( (a) \, \text{MA} = 0.54 \) - \( (b) \, \text{MA} = 1.86 \) - \( (c) \, \text{MA} = 2.06 \) - \( (d) \, \text{MA} = 2.17 \) *Reference: See "Theory of Machines and Mechanism," 5th Edition, Problem 1.27.* The mechanism appears to be moving with rotational inputs and the mechanical advantage (MA) is to be determined from the given options.
