Explain the formation of patterned ground and stone stripes. (15 marks) Patterned ground is a very distinct feature in peri-glacial regions‚ and is found in places such as the Antarctic Peninsula. They generally take the form of a polygons (which may form tessellations)‚ or circles. It is caused by a process called frost heave‚ and can in some cases be the result of stone stripes. Frost heave is the initial cause of patterned ground‚ and this process is a result of the summer months melting the

Represented mathematically as approximately 1.618033989‚ and by the Greek letter Phi‚ the number tends to show up frequently in geometrical shapes. For example‚ the golden ratio is the basis for the construction of a pentagram. This shape looks like a regular star; five straight lines form a star with five points. The pentagon within the star in the center is proportional to the points of the star by a ratio of 1: 1.618. The golden ratio appeared so much in Geometry‚ as stated above with the pentagram

holes. At present square and other non holes are produced using CNC machines or spark erosion or slotting machines. But there is no quality machine tool to produce square and polygon holes at minimum cost. Thus we made an attempt to design and fabricate an attachment for drilling machine which would produce square and polygon holes much more easily than the current method. This will be very useful to seat bolt heads etc. This attachment can be though of an inversion of the “Cam and Ball mechanism

find out how many degrees there are in a polygon. Pythagoras came up with (n-2)180°= the number of degrees in a polygon‚ where (n) represents the number of sides in the polygon. For example‚ a triangle has three sides‚ 3-2=1‚ 1x180=180‚ which is the total sum of all the inner angles of a triangle. Along with that he found out that the sum of all the outer angles of a polygon is always equal to three hundred sixty degrees. This is true for every single polygon‚ regardless of the number of the sides
