Design a basic attitude control system for a spacecraft. The system should be able to maintain the spacecraft's orientation within certain limits, and should be able to rotate the spacecraft about one or more axes. The system should also be able to compensate for any external forces acting on the spacecraft, such as solar radiation pressure or gravity.

Assuming a spacecraft is in low Earth orbit with an apogee of 400 km and a perigee of 300 km, and is not maneuvers for the purposes of this exercise, what is the minimum delta-v required to maintain a 3:1 ratio between the apogee and perigee?
The minimum delta-v required to maintain a 3:1 ratio between the apogee and perigee is 0.4 km/s.

A 100 kg wooden crate rests on a wooden ramp with an adjustable angle of inclination.
The angle of the ramp is set to 10°, determine:
the component of the crate's weight that is perpendicular to the ramp.
the component of the crate's weight that is parallel to the ramp
the normal force between the crate and the ramp.
the static friction force between the crate and the ramp.
At what angle will the crate just begin to slip?
