Solve each of the following problems. Show your solution. 1. A hydraulic lift office chair has its seat attached to a piston with an area of 11.2 cm2. The chair is raised by exerting force on another piston‚ with an area of 4.12 cm2. If a person sitting on the chair exerts a downward force of 219 N‚ what force needs to be exerted on the small piston to lift the seat? Answer: a= 11.2 cm2 A= 4.12 cm2 f= 219 N F= 80.56 N F= fA / a ;

Lab Report: Stoichiometry Lab Oct. 27‚ 2011 Claire Elizabeth Lab Partners: Hannah Signature:___________________ Introduction- Baking soda and vinegar are two common materials found in almost every household. That‚ plus the fact that all the starting and finishing materials are non hazardous and safe‚ is why this is one of the first chemical reactions that many people are exposed to The purpose of this experiment tests which of the two reactants (vinegar and baking soda) is the limited

This lab has introduced the use of daphnia‚ pill bugs‚ amoeba and Uglena. We the AP Biology students were first introduced to the test subjects to test his or her capability of handling living organisms for upcoming science experiments. The AP Biology students were asked to create original experiments for all test subjects testing reactions to gravity‚ light intensity and reaction to food. Daphnia‚ or Daphnia magna‚ are microscopic organisms in which the students created an original lab to test

Unit 7 Assignment Kaplan University MT140 Introduction Professor: Laurie Kyriakopoulos April 13‚ 2014 While visiting all of their operating locations has heard how successful they have been using the team approach. If Dalman and Lei would assign managers under them they would be able to be more equipped to handle the daily activities of Sandwich Blitz. The self-managed teams would require training to be able to determine what type of training would help the handle the

Lab Report 7: Analysis of Cereal Introduction: The objective of this lab was to consult for the FDA regarding a recently surfaced scandal involving false reporting of iron content in cereal as well as iron tablets. The makers of the cereal and the iron tablets‚ respectively‚ were allegedly reporting higher amounts of iron in their products than actually existed‚ as a way to save money but continue to provide products with “adequate” amounts of iron. The FDA needed consulting in order to analyze

The solver is using a full-scale time-marching 3D viscous model. Underlying equations‚ three dimensional Navier-Stokes equations in their conservation form‚ are being solved by using a Finite Volume method‚ where equations are integrated over the finite control volumes. Thereby‚ the solution domain is subdivided
