Performance Task no. 4.1 Pressure Principle I. Introduction Why is theater seat so much more comfortable than a bicycle seat? One of the main reasons any seat is comfortable is the pressure it exerts on your body. This performance task aims to know the importance and application of pressure. Pressure is defined as the force acting perpendicular to a unit area. It is the result of a force distributed over an area. A theater seat’s large padded seat and back offer a larger area to support your

Introduction Hydrostatic weighing is an indirect measurement used to predict body fat percentage. It is typically the most accurate means of determining body fact percentage‚ and is based on measuring an individual’s body density. Archimedes’ principle explains that the upward buoyant force exerted on a body immersed in a fluid is equal to the weight of the fluid that the body displaces. Due to the fact that body fat is less dense than water‚ it increases one’s buoyancy‚ while the fat-free mass

Images offer a powerful way to communicate. A single image can relate more to a person than text can. An artist can create a piece of artwork to express how he or she feels or how they see something. Over time the art that was created long ago can change meaning from what the artist originally intended and the perception can change as well‚ either through mystification or personal experiences. Author John Berger in his book Ways of Seeing writes about the various ways in which this can happen. By

| HYDROSTATICSHydrostatics is that part of the general science of hydrodynamics that deals with the application of forces to fluids at rest. Among the chief principles of hydrostatics may be mentioned the following:(1) The intensity of pressure at any point of a fluid is the same in all directions; it is the same whether the surface that receives the pressure faces upwards‚ downwards‚ horizontally or obliquely.(2) When a fluid is confined‚ if the intensity of pressure in one part is increased‚ as

• A typical surfer starts at a spot in the water where waves begin to form. They then turn towards the shore. When the surfer sees a wave‚ they paddle towards the beach along with the wave. • When water catches the surfboard‚ the surfer then stands up on the board and soars along the waves crest. • Surfing was discovered first in Hawaii • In 1821‚ surfing was banned by missionaries because they thought it was immoral to surf. • A famous Hawaain swimmer by the name of Duke Kahanamoku Waves

The type of physics that I will be presenting is a branch of Fluid Mechanics. Fluid mechanics studies the physics of gases and liquids. Hydraulics is defined as: "a branch of science that deals with practical applications of liquid in motion." Merriam-Webster’s Medical Dictionary‚ via www.dictionary.com The science started over thousands of years ago with Aristotle (384-322 B.C.) and Archimedes (287-212 B.C.). Many European scientists also contributed to hydraulics‚ including

The Safe Way Is The Best Way Reducing the risk of fire is critical to commercial resilience. The potential risk to human life‚ costly disruption to services‚ lost production‚ increased insurance premiums‚ mean that fire prevention should be a key feature of any business risk management strategy. A sizable fraction of ignitions of structures are due to electrical faults associated with wiring or with wiring devices. Surprisingly‚ the modes in which electrical faults progress to ignitions of structure
