a screw is basically an inclined plane wrapped around a pole, and an inclined plane is basically a ramp. a wedge is a double sided inclind plane and is mainly used to split things apart
screw thread
Why is the wedge and screw actually an inclined plane? Well, screws are actually tapering, if you take the ridge off and lay it flat. The screw is actually nothing but an inclined plane wrapped around a small pole. The wedge is an inclined plane because it starts at a point, then goes up, getting thicker, like an inclined plane. It's just that a knife's not used to lift a box of glasses onto a train. Imagine using an inclined plane as a knife!
A inclined plain wrapped around a pole.
Polarity means, what kind of pole, which would either be an electrical pole with a positive charge and a negative charge, or a magnetic pole with a south pole and a north pole.
A screw is like an inclined plane wrapped around a pole, envision a circular stairwell.

A inclined plain wrapped around a pole.
It spins on an axis that is tilted with respect to the plane of its orbit around the Sun. This tilt means that first one pole, then the other, is tipped toward the Sun as the planet circles the Sun. When the North Pole is inclined toward the Sun, it is summer in the Northern Hemisphere and winter in the Southern Hemisphere. When the South Pole is inclined toward the Sun, the Southern Hemisphere has summer and the northern has winter. Twice a year (spring and fall equinoxes) neither pole is tipped toward the Sun for a brief moment. On that day, day and night are about equally long (12 hours) for the entire planet. The axial tilt is about 23.5 degrees to the perpendicular to the orbital plane.

Because the Earth's axis of spin is inclined some 23 degrees in respect to the pole to the plane in which it orbits the Sun.
yes a flag pole is a sample machine
No. Neither end of the earth's axis points anywhere near Mars, so Mars doesn't appear anywhere near either celestial pole in the sky. Mars' orbital plane is inclined only 1.9 degrees to the plane of earth's orbit (the ecliptic plane). So Mars can never appear more than 1.9 degrees north or south of any point in the sky where the sun can ever appear.
