Challenge Problems
Push your limits with challenges.
Question 1
Design a four-bar linkage with the following lengths: s=2, l=6, p=4, and q=3. Test if it is Grashof type, then calculate what changes could make it Grashof type if it isn't.
💡 Hint: Revisit the length relationships.
Question 2
Evaluate a slider-crank mechanism's angle efficiency at a transmission angle of 30°. What adjustments would you recommend for better performance?
💡 Hint: Consider ideal angles and their role in mechanical efficiency.
