the measure in degrees from the horizontal axis to the major axis of an object.

the angle a rocket makes with the vertical as it curves along its trajectory

The angle that a flat plate collector surface forms with the horizontal plane.

See Inclination.

The angle at which an office chair's seat and back tilt simultaneously at the same ratio.

A fixed angle measured from the horizontal to which a solar array is tilted. The tilt angle is chosen to maximize the array output. Depending upon latitude, season and time of day this angle will vary.

The angle at which a solar array is set to face the sun relative to a horizontal position and is usually adjusted seasonally due to the changing declination of the sun.

The angle of the pen with respect to the writing surface, which is usually measured as angles of the projection onto x and y vertical planes

This is indicated in the scene's units below (negative) or above (positive) horizontal (0) at the base of the tilt bar.

The angle of inclination of a module measured from the horizontal.

The angle at which a solar collector or module is set to face the sun relative to a horizontal position. The tilt angle can be set or adjusted to maximize seasonal or annual energy collection.
