In a certain road construction undertaken by the DPWH, it was decided to connect a forward tangent of +3% and a back tangent of -5% by a 200 m. symmetrical parabolic curve. It was discovered that the grade intersection at 10 + 100 whose elevation is 100 m falls on a rocky section with an outcrop of 2.67 m. directly above the grade intersection. To avoid rock excavation, the project engineer decided to adjust the vertical parabolic curve in such a way that the curve will just clear the rock without altering the position of P.C. and the grade of the tangents. Determine the total length of the new parabolic curve. (Round off your final answer to three decimal places).

Types of Composite

Composite materials are formed by merging two components that have different chemical and physical properties. The merged output is termed as a composite, whose properties are completely different from the individual components. Composite materials also have better strength than the individual components.Composite materials usually have two main parts, reinforcement material, and matrix material. The matrix material acts as a binder and surrounds the fiber of another material that bears a much higher strength. This material is known as the reinforcement material. The matrix materials are usually high-strength additives resins, while the fibers of the reinforced material can be random, oriented, and in a mat format.Composite materials are also known as fiber-reinforced composite polymers because they are composed of the polymer matrix which is reinforced to laboratory-created fibers or naturally occurring fibers, such as glass fibers, carbon fibers, or aramid fibers. Under the application of external loads, the matrix material absorbs and transfers the loads to the fibers, these fibers in return provide good compressive strength, tensile strength, and stiffness to the fiber-reinforced composite materials.Depending upon the matrix and the reinforcement material, different properties can be induced to the fiber-reinforced composite materials, including good corrosion resistance properties. The most common matrix material is the resin while the glass fibers act as the reinforcement material. Strong fibers provide strength and stiffness to the composite materials while, a soft and flexible resin provides shape to the composite materials.
