increased load handling‚ longer lifetimes and corrosion resistance to name but a few. Engines in particular have received much attention. The engine and its components alone contribute to 15 percent of the total frictional losses in the vehicle. Aluminium alloys have more recently been preferred to cast iron to reduce the overall weight of the car‚ to improve fuel efficiency and road performance. However‚ as engine technology continues to develop‚ and more power is demanded from the unit‚ so the severity

Newtonian Mechanics 8.01 Units and Dimensional Analysis 1 Dimensions in Mechanics Physical quantities have dimensions. These quantities are the basic dimensions: - mass‚ length‚ time with dimension symbols M‚ L‚ T Other quantities’ dimensions are more complex: - [velocity] = length/time = LT-1 - [force] = (mass)(length) /(time)2 = MLT-2 - [any mechanical quantity] = Ma Lb Tc where a b‚ and c can be negative and/or non-integer 2 Base Quantities Name Length Time Mass Electric

GCSE Physics Coursework - Resistance of a Wire Coursework Resistance of a Wire Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Electricity is conducted through a conductor‚ in this case wire‚ by means of free electrons. The number of free electrons depends on the material and more free electrons means a better conductor‚ i.e. it has less resistance. For example‚ gold has more free electrons than

Creative Sports Design (CSD) manufactures a standard-size racket and an oversize racket. The firm’s rackets are extremely light due to the use of a magnesium-graphite alloy. Each standard-size racket uses 0.125 kilograms of the alloy and each oversize racket uses 0.4 kilograms; over the next two-week production period only 80 kilograms of the alloy are available. Each standard-size racket uses 10 minutes of manufacturing time and each oversize racket uses 12 minutes. Also‚ 40 hours of manufacturing time are

In the Unites States alone there was 360‚000 welders in 2012 and by 2022 there is supposed to be a 32% increase. This will create many more jobs for future welders. The process of becoming a welder varies on what type of welding you want to become certified in. There is many types of welding including mig‚ tig‚ arc‚ and others and for each type there is diffrent ways to do each one. Along with learning how to use the welders‚ you’re going to have to know how to use other machines like sanders‚ grinders
