Best Unit In The Game Mount And Blade

THE SUNDIAL (HORIZONTAL DIAL WATCH)

THE SUNDIAL (HORIZONTAL DIAL WATCH )
- Building sundials-

horizontal dial The watch like the previous case is a bit more complex in design than the equatorial quadrant, indicating divisions of the time does not correspond to the simple division into equal parts angular tilt 15 degrees per hour as in the case of sundials equatorial dial. In the same way as for vertical dial clocks, the gnomon of this watch now has a triangular shape has to be properly oriented parallel to the axis of the world. Once done, the time is indicated by the projection of the shadow of the upper edge of the triangle that makes the gnomon on the degree horizontal plane. The

following image shows the mathematical development to find the projection of the equatorial dial on the horizontal plane and thus obtain the horizontal sundial for our little project.


Made the path, we have the pattern for making the sun clock

Cut the pieces and assembled the watch, it keeps the look shown in the figures below.




Note in the picture the triangular shape of the gnomon, the inclination of the upper edge of the triangle with respect to the horizontal is just the angle that corresponds to the latitude of the place, so that once placed our sundial in a sunny spot, the top edge of the gnomon is parallel to the axis of the poles and pointing north. The time is marked by the shadow that is projected onto the horizontal dial.


Local Solar Time: 1:30 PM
