equal to the drag force‚ and lift is equal to weight. Any thrust available in excess of that required to overcome the drag can be applied to accelerate the vehicle (increasing kinetic energy) or to cause the vehicle to climb (increasing potential energy).

analysed and particular modifications such as the implementation of wing twist and the introduction of wingtip devices are discussed as possible retrofits. Issues being investigated: induced drag caused by the production of lift especially though take-off and landing configurations in aircraft‚ parasite drag caused by the modifications such as winglets‚ implementations of the modifications. Concluded is the success of the project and whether the proposed modifications are a realistic improvement

Ranking Salt Solutions by pH 6-2: Ranking Salt Solutions by pH In this assignment you will be asked to rank aqueous solutions of acids‚ bases‚ and salts in order of increasing pH. This is most easily done by first identifying the strong acids that have the lowest pH‚ the strong bases that have the highest pH‚ and the neutral solutions that have a pH near 7. The weak acids will have a pH between 1 and 6 and the weak bases between 8 and 14. The exact order of weak acids and

The longbow has been used over the years‚ first as a weapon to hunt‚ later as a war weapon‚ and now its used as a sport‚ but its physics had always been the same over the years‚ regardless of its use. This physics involves two components: bow mechanics and arrow flightBow mechanics: when an archer pulls back the string‚ he does work on the bow‚ and is converted to potential energy. Upon release of the arrow‚ this potential energy is converted into kinetic energy‚ most of which is transferred to the

tips used to increase the performance of an aircraft by reducing wingtip vortices and increasing the lift-to-drag ratio. Winglets were first studied by Richard Whitcomb in the late 1970’s to improve upon aircraft efficiency at a time when fuel conservation was necessary to save on costs with the rising fuel prices. Whitcomb found that winglets could offer an improvement in the lift-to-drag ration over planar wingtip extensions at the same level of the root bending moment. His contributions have led

Addressing this question‚ I will argue that drag women are only acceptable when they are to entertain heterosexual bodies on television. I will draw from Butler’s Gender is Burning and the 1980 film Paris is Burning and then define my findings in the summary. In the film the success of drag is being judged by the extent to which ball contestants must pass meaning to be read as normal opposed to being read meaning
