PROBLEM 18.83 (Beer Johnston)
The uniform thin 2.5-kg disk spins at a constant rate \omega _(2)=6ra(d)/(s) about an axis held by a housing attached to a horizontal rod that rotates at the constant rate \omega _(1)=3ra(d)/(s). Find the
force and mament of couple acting on the rod at A (Ao is massless)(1)/(x)((hat(e_(1)))), AO=1m (at this instant)
F_()=24.5N vertically up
C_()=-0.225Nmhat(e)_(2)+24.5Nmhat(e)_(3)
Dx_(1)((hat(e_(1))))x_(2)(hat(e)_(2))x_(3)(hat(e)_(3)) is fixed to the disk.
