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 ;

NRES 102 Assignment 3 Renewable energy sources are vital to the survival of our population as well as saving the environment. Fossil Fuels are going to run out‚ it is inevitable‚ so more needs to be done to increase the utilization of renewable energy. One of our main sources of energy is oil. There is only a finite amount though‚ and even though we only started using it around the 1900s‚ it will all be gone around 2100. This gives us time to learn more about renewable sources‚ but in the end the

Unit 5. Lab. New Building-Wired and Wireless If I choose to design the new building with a wired network the main benefit is there would be a low chance on interception. Choosing a wired network will also have a lower risk of security issues; reliability and speed are primary benefits as well when using physical connections in a wired network. The basis of the new building will relay on loads of data to be moveable that is why a wired network allows the control. Wired LANs provide superior performance
