In reading #5 I learned about how Force can change an object by pulling or pushing. Force represents as a vector, which means it has both magnitude and direction. There are different types of forces such as: Collinear force, Concurrent force, Parallelogram, Similar manner, Polygon method, and Nonconcurrent force. I also learned about Structural loads, bends, or accelerations applied to structure components. Loads cause stress, bending and movements in structure. Also learn how to place structural column, beams, trusses and frames. Plate structures are stiff, planar and usually solid structures which can take loads in lots of directions. Plate structures is a reinforced concrete slab. They can provide a variety shapes and overall forms like:  rectangular plates, non-rectangular plates and triangular or trapezoidal plates.
