What governs the direction of the Coriolis acceleration component _____________________?
Show answer Hide answer
Answer: A. of relative velocity vector for the two coincident points rotated by 90° in the direction of the angular velocity of the rotation of the link
Explanation
Coriolis acceleration is directed along the relative velocity vector rotated by ninety degrees. This ninety-degree rotation occurs in the exact direction of the link's angular velocity vector. Vector cross products of angular velocity and relative velocity determine this specific orientation. Coriolis acceleration occurs when a point moves outward along a rotating link or slider. The magnitude equals twice the product of angular velocity and relative sliding velocity. It combines rotational and linear motion effects into a single acceleration component.
Quick-return mechanisms and slider-crank assemblies generate Coriolis components that must be analyzed. Mechanical engineers design high-speed machinery while accounting for Coriolis forces on moving sliders. Accurate acceleration analysis prevents unexpected dynamic stresses in complex industrial automation. Option B places it along centripetal acceleration, ignoring the unique direction of sliding velocity. Option C aligns it with tangential acceleration, confusing different vector components in mechanisms. Option D suggests an incorrect perpendicular relationship relative to angular velocity vectors.
