Question
Advanced Controls and Dynamics II is desired lo change the oriental ion of a rigid body R; initially the frame coincides with a ground (global) frame f_g; in the desired configuration, the unit vectors i.k of G are desired to be oriented as follows: What is the desired rotation matrix? Suppose one desires lo attain this relation matrix only through clcmenlary body-fixed rolalions. What should the appropriate angles be if the body is rotated about its i-axis followed by a rotation about its.r-axis followed by another rotation about its =z-axis? Suppose the second rotation in the sequence were to be about the y-axls, how would the angles change? if the body were to be rotated about an appropriate axis so that the desired rotation is attained in one rotation, what are the direction cosines of the axis and What is the desired angle of rotation about this axis?Explanation / Answer
The height of the ground rigid body when Use Ground Collisions is on. Specified in the active units.
For reference, Earth's gravity is approximately –981.001 cm/s2 = –386.221 in/s2 = –32.185 ft/s2 = –9.81 m/s2 .
This option uses the same scale as the MassFX gravity but with positive rather than negative values, so for earth-realistic gravity, set the space warp Strength to 386.221 if System Unit Scale is set to 1.0 Inches. For other system units, see Acceleration, preceding.
The main benefit of using this option is that you can apply gravity in any direction by rotating the space warp object. The Decay option has no effect, and the gravity always uses the Planar option; setting it to Spherical has no effect.
Tip: You can apply different gravity settings to individual objects with the Forces rollout settings.

If collisions and constraints don't seem to be working properly in the simulation, try adjusting these settings.
