Question 1
What is the equation for calculating the velocity of a point A at a coincident point?
- v_A = v_B + v_{A/B}
- v_A = v_B - v_{A/B}
- v_A = v_B Γ v_{A/B}
π‘ Hint: Focus on how A relates to B and its own relative velocity.
Question 2
True or False: The Coriolis component is irrelevant in the analysis of coincident points.
- True
- False
π‘ Hint: Consider systems where parts rotate.

Challenge Problems
Push your limits with challenges.
Question 1
You have a mechanical arm where point O is a coincident point between two links. If link 1 rotates with an angular velocity of 30 degrees per second clockwise and link 2 is sliding past it at a constant speed of 2 m/s, calculate the velocity of point O.
π‘ Hint: Pay attention to the direction and consider both linear and angular speeds.
Question 2
In a slider-crank mechanism, the crank rotates at Ο = 60 rad/s and the radius is r = 0.4 m. What is the relative acceleration experienced by a point on the slider when the crank is at its horizontal position? Include the Coriolis component in your calculations.
π‘ Hint: Break down the components of each acceleration; it's essential.
