Challenge Problems
Push your limits with challenges.
Question 1
Consider a four-bar linkage where the lengths are given as L1 = 5m, L2 = 7m, and L3 = 9m. Determine if the mechanism can be closed and derive the loop closure equation.
💡 Hint: Look into the geometric constraints between the lengths.
Question 2
A slider-crank mechanism is working during a cycle. If the angular position of the crank is given, derive the position vectors for all components and apply the loop closure equation to find the slider’s position.
💡 Hint: Use trigonometric relationships to find positions based on the crank angle.
