### Problem Statement: Determining Stress Ratio of a Link in a Mechanism A link in a mechanism is made from a round bar. Due to the loading condition, the link is subject to a maximum stress of 67 MPa and a minimum stress of -27 MPa. #### Question: Determine the link's Stress Ratio \( R \)? #### Options: - \( 0.40 \) - \( -0.40 \) - \( -0.43 \) - \( 2.35 \) - \( 2.48 \) - \( -2.48 \) - \( 0.43 \) - \( -2.35 \) #### Explanation: In the context of mechanics, the stress ratio \( R \) is given by the formula: \[ R = \frac{\text{Minimum Stress}}{\text{Maximum Stress}} \] Using the given maximum stress (\( \sigma_{\text{max}} = 67 \) MPa) and minimum stress (\( \sigma_{\text{min}} = -27 \) MPa), calculate \( R \) using the above formula: \[ R = \frac{-27}{67} \] This calculation will help in selecting the correct answer from the provided options.
