to the blades. As a result of this gear reduction unit the angular velocity and acceleration of the shaft entering the generator is much greater than that of the shaft connected to the blades. The greater velocity and acceleration causes a greater number of revolutions in the turbine and effectively increases the power output of the turbine had that gear box not been installed, and had a direct transfer of mechanical energy into electrical energy of the generator. On the more detailed scale on wind energy and its relation to the subject of dynamics are the means in which the elements of it can be analyzed. For instance, as we have been learning of late, rigid body kinematics can be analyzed in a number of ways. We can analyze a rigid body that simply translates itself in motion, a body rotating about a fixed axis, and a body experiencing planar motion. In this case it’s clear that most elements in a wind turbine system rotate about a fixed axis. By inferring this it is necessary to determine what the elements rotate about in wind turbine. Most clearly this axis would be a shaft or maybe the center of a gear depending on the area of focus when analyzing the mechanics of the system. Having knowledge of kinematics it could be inferred that the angular velocities and accelerations of the blades at any point along there length could be found. They could be found by determining an instantaneous center of zero and then choosing a point along the length of the blade. The angular…

between body coordinates and movements/positions of figure skating. I will be investigating the relationship between the body’s initial and interim positions and the outcome of a figure skater’s trajectory during a jump as well as a figure skater’s angular momentum during counterclockwise rotational spins. A figure skater is trained to use a double axel, a jump with forward takeoff, with a split jump to create a parabolic leap in the air. A double axel contains an additional rotation in the…

The flips involves the jumper to first create a rotational motion around their centre of mass. This is done to create angular momentum which ensures the spin occurs and must have a net force greater than zero. The angular momentum occurs around the centre of mass for the dive, which is often around the belly button region on the body in a tight ball. Angular momentum is the product of angular velocity and rotational inertia. The momentum remains the same throughout the dive, however for the…

Unbalance is the most influential reasons of vibration on a rigid rotor. When designing high speed rotors and precise rotors, it is a important factor to be considered in the design. The way which used in the experiment is add the unbalance mass on the rotor, then, make whole system be balanced. The report has contained two tables which show the results collected from the experiment. It has included four diagrams, two tables and discussion section for results. Theory[1] Rigid Rotor:…

Energy and Planar Kinetics of a Rigid Body: Work and Energy. Kinetics of a particle: work and energy shows the particle moving when forces are applied to it and produces work and energy. Meanwhile under planar kinetics of a rigid body shows the rigid body on the plane when forces are applied and produces work and energy. There are similarities and differences between both of it. Kinetics of a particle Planar kinetics of a rigid body Similarities - Conservation of energy - Conservation forces…

What is the Unlimited Spirit, Limited Spirit and Corporeal Bodies? We differentiate three distinct types of beings here. One is the highest good in which nothing can surpass. This highest good is God; God is the only unlimited spirit with no end, no beginning and is not limited by space or time. The unlimited spirit has always been and will always be. The limited spirits are all the angels and human spirits that have a beginning, no end and the human spirits are limited by space and time…

On Saturday, I went and saw the play Arsenic and Old Lace at the Artisan Theatre in Bedford. A brief synopsis of the play is about a house that is owned by Abby and Martha Brewster with four others who reside in that house. One is Mortimer, Abby and Martha Brewster nephew, who is also in love with the reverend’s daughter, Elaine. Mortimer then decides to ask Elaine to marry him with which she responds yes to. Then after getting engaged, she goes and tells her father, the reverend. Elaine is now…

checks every window one last time, and finding no lights or sounds outside, she lifts the pot up. It seems agonizingly heavy to her weak arms, and she hastily sets it down on the floor and lifts the lid. There is nothing but a large, grimy-looking chunk of meat in plain boiling water. They’ve eaten everything else there is, even the shriveled, unripe mini tomatoes on her decorative plant. It died more than two months ago, and the small, dried fruits tasted like sand when she tried to eat them. A…
