The angular speed is converted into a directly dependent voltage signals. The voltage thus generated is fed to a speedometer for speed measurement and /or used as a feedback signal for controlling the speed of a rotating shaft. An electromechanical generator is a device capable of producing electrical power from mechanical energy‚ usually the turning of a shaft. When not connected to a load resistance‚ generators will generate voltage roughly proportional to shaft speed. With precise construction

+Amendments for D2: Skeletal muscles allows for many different types of muscle contractions such as eccentric‚ concentric‚ isometric and isokinetic. These muscles are voluntary and the contractions produced have a huge impact on Wilkinson’s game. For example when he is striking a ball his quadricep contracts concentrically to produce force onto the ball. The more powerful the muscle the bigger the contraction‚ therefore if Johnny improves the strength of his quadriceps his kicking distance could

History: Margaret Donovan‚ a 72-year-old white female‚ was brought to the emergency room by her son-in-law after falling in her bathtub. She was previously in good health‚ despite leading a relatively sedentary lifestyle and having a 30-year history of cigarette smoking. The only medication she currently takes is Inderal (propranolol)

Results A left gastrocnemius muscle of a frog (L=3.2cm in situ) was used in experiment 1 and 2‚ while a right gastrocnemius muscle of a frog (L=3.4cm in situ) was used in experiment 3. The sciatic nerve of the frog was placed over the stimulatory electrodes covered with a piece of a Kimwipe moistened with Ringer’s solution. The relationship between muscle length‚ force production and velocity of contraction was studied. Force transduced calibration In order to get a more accurate data from force

Voltage: Ohm ’s Law and Kirchhoff ’s Rules ABSTRACT Ohm ’s Law and Kirchhoff ’s rules is fundamental for the understanding of dc circuit. This experiment proves and show how these rules can be applied to so simple dc circuits. INTRODUCTION In the theory of Ohm ’s Law‚ voltage is simply proportional to current as illustrated in the proportionality‚ V=RI. As shown in this relation‚ V represent voltage which is the potential difference across the two ends of a electrical conductor and between

part in the sporting performance of the athlete both in physical and mental terms. The athlete needs to learn to notice the signs of fatigue and tension that arises from this and introduce methods to cope with the debilitating effect it can have on their performance. Muscle fatigue and the tension associated with it can result from a number of different factors. The athletes may simply have over exerted themself physically in training or competition leading to muscular fatigue from pushing their physical

Muscle spasms are involuntary contractions of muscles that are often very painful. Muscle spasms are also called cramps or referred to as a “Charley horse”. These contractions are most frequent on the leg muscles but can also occur in the hands‚ arms and abdomen. (www.webmd.com) Typically the muscles become very hard and tight. There are many causes of muscle spasms. The most common cause is overuse during athletic activities such as sports or general exercise. Other causes include not

The basis for theories of behavior management focus on these ABC’s: Antecedent event or stimulus. In behavior management‚ it is critical to count and examine the specific events that precede behavior; Behavior or response of the student. This is the specific‚ observable and measurable behavior that is targeted; and Consequent event or reinforcement of behavior. In behavior management‚ the impacts of a variety of reinforcements or rewards are considered so that the most reinforcing reward is chosen

situations‚ current density varies in different parts of an electrical conductor. A classic example is the so-called skin effect‚ in which current density is high near the outer surface of a conductor‚ and low near the center. This effect occurs with alternating currents at high frequencies. Another example is the current inside an active electronic component such as a field-effect transistor (FET). An electric current always
