This technology is even simpler to explain. RF is a kind of electric current that travels back and forth in different directions. It can be applied in such a way that it travels through your entire body from one side and out the other or between a 10mm gap using a small hand piece, just along the surface of your skin.
Lesson Summary. A post and lintel is an architectural system where a horizontal piece is supported by two vertical posts, or columns. This is a basic form of architecture that has been used since ancient times, but the Egyptians used it for monumental architecture, or buildings that are massive in size and scale.
The post are connected to the footings and the beams. The weight of the joist and everything above the joist is transferred to the post. Most decks use 4 x 4 inch post or 6 x 6 inch post. The higher the deck is from grade the larger the post should be. The post transfers the weight of the deck, joist and beams to the footings.
