Question

2/203 The spacecraft with attached x-y-z axes is tumbling about the x-axis at the constant rate ? = 2 rad/s. Determine the acceleration of point A on the tip of the solar panel as the x-axis comes in line with the center of the earth if the panels are unfolding at the rate ?? = 4 rad/s with ?? = 6 rad/s² for the position ? = 30°. The mass center G of the spacecraft has an acceleration a? = 6 m/s² toward the earth's center, which is here considered fixed in space. The hinge axes B and C for the panels are 0.6 m apart and 0.2 m "below" G. Ans. a? = 0.729i + 19.2j – 48.0k m/s²

Step 1

The x-axis is aligned with the tumbling axis of the spacecraft, the y-axis is perpendicular to the x-axis and in the plane of the solar panels, and the z-axis is perpendicular to both the x and y axes, pointing towards the center of the Earth. Show more…

2/203 The spacecraft with attached x-y-z axes is tumbling about the x-axis at the constant rate ω = 2 rad/s. Determine the acceleration of point A on the tip of the solar panel as the x-axis comes in line with the center of the earth if the panels are unfolding at the rate φ̇ = 4 rad/s with φ̈ = 6 rad/s² for the position φ = 30°. The mass center G of the spacecraft has an acceleration ā = 6 m/s² toward the earth's center, which is here considered fixed in space. The hinge axes B and C for the panels are 0.6 m apart and 0.2 m "below" G. Ans. aₐ = 0.729i + 19.2j - 48.0k m/s²
