1908. Unlike other designs‚ the dimple proved to be the most aerodynamically efficient. Dimpled balls fly farther than non-dimpled balls due to the combination of two effects. There is drag‚ which is the force acting opposite to the object to slow it down‚ lift which is the force acting at a right angle to drag and generally upwards‚ and gravity. How is lift created? Newton’s third law states that for every action there is an equal and opposite reaction. The ball when spins exerts a force

in me falling off of a lot of waves. There are two biomechanical principles that help explain propulsive forces produced by a surfer when paddling through the water‚ these include: * Drag force * Lift force Drag force: Definition: Drag force is due to pressure difference (Amezdroz‚ et al‚. 2010). Drag force is used to propel a surfer in water. “As the hand is pulled back in the water‚ the water then flows or travels past the hand and becomes turbulent at the back of the hand. This fast

it is viewed as natural. The culture of drag serves as a testament to this. Drag culture points out that gender is in fact a form of impersonation‚ as the purpose of the culture is to imitate women (Butler‚ 1993). Butler states that this imitation of women corroborates the notion gaining cultural acceptance only requires some cosmetic changes as well as mannerism‚ which are not inherent qualities that women have from birth (Butler‚ 1993). Ultimately‚ drag goes against the norms people accept as the

In a calling to arms‚ a leader must portray his confidence and support of the people he is speaking to. Queen Elizabeth I had to put forth more effort when rallying her army then a king would; she was a woman. In calling her army to arms‚ Queen Elizabeth I of England utilizes certain elements of language-diction‚ imagery‚ and sentence structure-to let them see the truth in what she said. Queen Elizabeth I implements diction in her speech to her people. Elizabeth begins her speech with the words‚

Alexa Rae Drake Poem Analysis November 30‚ 2013 NNU (Title) Queen Elizabeth I was a powerful cultural figure and Queen of England from 1533-1603. She was remarkably influential that her reign is now commonly referred as the Elizabethan Era. Queen Elizabeth I wrote “The Doubt of Future Foes” at a time when rebellion was stirring among her subjects. Elizabeth’s cousin‚ Mary‚ Queen of Scots was spreading rumors and lies of dishonesty and disloyalty on Elizabeth’s reputation. Though Elizabeth

ABSTRACT One of the most widely used methodologies in characterising the quality of a wind tunnel is to study the flow over a sphere.The flow around the bluff body was characterised using smoke test‚ and the region of flow separation was analysed. The drag characteristics of 3 spheres of different diameters were studied for a wide range of Reynolds number. The Reynolds number at which the transition occurs is strongly dependent on the degree of turbulence in the wind tunnel. Based on the following tests
