Cubism is an early-20th-century avant-garde art movement pioneered by Georges Braque and Pablo Picasso, joined by Jean Metzinger, Albert Gleizes, Robert Delaunay, Henri Le Fauconnier, Fernand Léger and Juan Gris that revolutionized European painting and sculpture, and inspired related movements in music, literature and architecture. Cubism has been considered the most influential art movement of the 20th century. The term is broadly used in association with a wide variety of art produced in Paris during the 1910s and extending through the 1920s. Variants such as Futurism and Constructivism developed in other countries.

van Gough research

Vincent van Gogh (Dutch:; 30 March 1853 – 29 July 1890) was a post-Impressionist painter of Dutch origin whose work, notable for its rough beauty, emotional honesty and bold colour, had a far-reaching influence on 20th-century art. After years of painful anxiety and frequent bouts of mental illness, he died aged 37 from a gunshot wound, generally accepted to be self-inflicted (although no gun was ever found). His work was then known to only a handful of people and appreciated by fewer still.

When i draw in the style of van Gogh i like to show all the brush marks just as he did he used them in a favour against him instead of him trying to paint too realistic he paints in a abstract manor he shows expressionism in the colour tones that he uses for different portraits the eyes in his paintings are all different showing different feelings and emotions.

The image above's one of my most loved pieces of art of all time let alone van Gogh's  like the way all the colors are layyed out and how the paint strokes on the page show what and how the wind flows by using the same color in different shades the yellow shades on the coat and stars really break up the landscape. As you may see I used expressionism and the way van gogh paints into one self portrait/ transcript. I had to use the same colors and us the same brush strokes that van gogh used, what I found difficult and time consuming was the smaller brush strokes on the jacket, I used yellow and blue and white to show different tonal value, I enjoyed painting in the same way as van gogh because I was happy with the final result, The idea of joining the expressionism portrait and the van gogh transcript was when i was looking through my folder I found both and thought why not.  

the bridge i will be making is a beam

The beam bridge is the most common bridge form. A beam carries vertical loads by bending. As the beam bridge bends, it undergoes horizontal compression on the top. At the same time, the bottom of the beam is subjected to horizontal tension. The supports carry the loads from the beam by compression vertically to the foundations.

When a bridge is made up of beams spanning between only two supports, it is called a simply supported beam bridge. If two or more beams are joined rigidly together over supports, the bridge becomes continuous.

All bridges need to be secure at the foundations and abutments. In the case of a typical overpass beam bridge with one support in the middle, construction begins with the casting of concrete footings for the pier and abutments. Where the soil is especially weak, wooden or steel piles are driven to support the footings. After the concrete piers and abutments have hardened sufficiently, the erection of a concrete or steel superstructure begins. Steel beams are generally made in a factory, shipped to the site, and set in place by cranes. For short spans, steel beams are usually formed as a single unit. At the site, they are placed parallel to each other, with temporary forms between them so that a concrete deck can be cast on top. The beams usually have metal pieces welded on their top flanges, around which the concrete is poured. These pieces provide a connection between beam and slab, thus producing a composite structure. 

Chairs and Ergonomics

What Features Should a Good Ergonomic  Chair Possess?

• Seat height. Office chair seat height should be easily adjustable. A pneumatic adjustment lever is the easiest way to do this. A seat height that ranges from about 16 to 21 inches off the floor should work for most people. This allows the user to have his or her feet flat on the floor, with thighs horizontal and arms even with the height of the desk.
• Seat width and depth. The seat should have enough width and depth to support any user comfortably. Usually 17-20 inches wide is the standard. The depth (from front to back of the seat) needs to be enough so that the user can sit with his or her back against the backrest of the ergonomic office chair while leaving approximately 2 to 4 inches between the back of the knees and the seat of the chair. The forward or backward tilt of the seat should be adjustable.
• Backrest. The backrest of an ergonomic office chair should be 12 to 19 inches wide. If the backrest is separate from the seat, it should be adjustable in height and angle. It should be able to support the natural curve of the spine, again with special attention paid to proper support of the lumbar region. If the office chair has the seat and backrest together as one piece, the backrest should be adjustable in forward and back angles, with a locking mechanism to secure it from going too far backward once the user has determined the appropriate angle.
• Seat material. The material on the office chair seat and back should have enough padding to be comfortable to sit on for extended periods of time. Having a cloth fabric that breathes is preferable to a harder surface
