Introduction During this lab you will become more familiar with the concepts of torque. The purpose of this lab is to determine if the rotational equilibrium condition‚ Στ = 0‚ holds experimentally. Equipment Meter stick (1) - no metal ends Fulcrum (1) Clamps (4) Weight Hanger (1) Mass Set (1) Digital Scale (1) Theory For a body to be in static equilibrium‚ two conditions have to be met: ΣF = 0 and Στ = 0 where F is force and τ is torque. (The torque is the force times the lever arm‚ r) The first

relates to the laws of mechanics and physics to human performance (Shooting Techniques Biomechanics‚ 2007). However psychology is the study of the mind and behaviour. Some biomechanics principles that are related to archery include balance‚ first class levers‚ newtons first law of motion and the projectile/height of the release of the arrow. Static balance refers to balance in the situation in which a set position must be maintained for a period of time‚ as in target sports like archery ad shooting; here

Pull through required amount of cable (Do not overrun cable drum by deploying too quickly). 4. Anchor machine and cable shackle with the correct sling. 5.

Achievement standard 90963 Basic anatomy: During the activity of kicking a football a person will use most of the muscles and joints in their body to perform the movement. Many of these muscles and joints may only play a small role in the movement but will affect the overall quality of the kick. Because of the amount of muscles and joints used in the kick I have chosen to only discuss the most important to the skill of each to discus. The three main joints used to perform a kick in football are

"Ergonomics" is the discipline that examines the capabilities and limitations of people. The term ergonomics is based on the two Greek word "ergon" and "nomos"‚ which together mean "the laws of work". In terms of design‚ the focus of ergonomics is man; and it aims to design appliances‚ technical system and tasks in a way to improve human safety‚ health‚ comfort and performance. Also‚ it makes products easy to be used. In the following paragraphs‚ I will discuss a number of factors including: the

Empty the hopper of all fertilizer‚ either by spreading the product on your garden or lawn or removing the fertilizer and returning it to its storage bag. 2. Open the hopper trough at the bottom of the spreader so water can run through. Pull the lever on the side of the spreader to open the trough. 3. Wash the spreader inside and out with a garden hose or power washer. The power washer works faster to remove fertilizer particles that may have dried and hardened on the equipment. 4. Wipe down

is my major fault. Every lever has a point at which a certain force is applied‚ also a point of a fulcrum and a point of resistance‚ but the three different types of levers all play a role in sport and physical activity but still work slightly differently. The third- class levers have a force in between the resistance and the fulcrum; our forearms act as a third-class lever‚ with the elbow as the fulcrum or point of rotation of the lever. Through the third-class levers I can relate my personal performance

the same lever. The distance of the applied force from the fulcrum is 2.00 m and the distance from the fulcrum to the load is 0.500 m. A graph of resistance force vs. effort force is shown. What is the mechanical advantage of the lever? What is the ideal mechanical advantage of the lever? What is the efficiency of the lever? Show your work. Answer: mechanical energy is always constant KE+ PE= constant Mechanical advantage = 0.25 Ideal mechanical advantage = 1 Efficiency of the lever = 0.25 or
