What is the equation for calculating the velocity of a point A at a coincident point?
💡 Hint: Focus on how A relates to B and its own relative velocity.
True or False: The Coriolis component is irrelevant in the analysis of coincident points.
💡 Hint: Consider systems where parts rotate.

Challenge Problems
Push your limits with advanced challenges
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.
💡 Hint: Pay attention to the direction and consider both linear and angular speeds.
In a slider-crank mechanism, the crank rotates at ω = 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.
💡 Hint: Break down the components of each acceleration; it's essential.
