Theory 2.1 Introduction A gear train is two or more gear working together by meshing their teeth and turning each other in a system to generate power and speed. It reduces speed and increases torque. To create large gear ratio‚ gears are connected together to form gear trains. They often consist of multiple

(rad/s) = Average speed (rpm) x 2 π/60 * Torque (N·m) = Load (N) x radius of wheel (0.026 m) * Input power (W) = Pressure (N/m2) x Flow rate (m3/s) * Output power (W) = Torque (N·m) x Average speed (rad/s) * Efficiency = (Output Power / Input Power) x 100% Discussion: 1. 2. Based on the graph of output power against speed‚ the trend is as the speed increases‚ the output power decreases. The same trend followed for the graph of torque

The principle of acceptance is that the offer must be accepted on the same terms it was made. Mr Wrench offered to sell some property to Mr Hyde for £1‚000 on the 6 June. Two days later Mr Hyde made a new offer to buy the property at a lower price for £950. This was a counter-offer and was rejected by Mr Wrench. Mr Hyde then said he would accept the original price of £1‚000‚ but Mr Wrench refused to sell. Explain what is mean by a counter-offer Do you think Mr Hyde’s original

huge collection of things he would find that he would make things with. He has painted many portraits of himself and other people as an inspiration. He has invented a lot of things but three things have been very well-known. They are the clincher wrench‚ electric brake‚ and windmill. One of his first inventions was an electric brake. It was invented in 1901. The electric brake was made for trains and street cars. When Ochoa made the electric brake he sold it to a company to make money. Ochoa

To determine the Isentropic Efficiency of a Turbine. 3. To compare the characteristics of a reaction turbine at different values of inlet pressure. 4. To compare the maximum shaft power vs pressure and isentropic efficiency vs pressure. Theory Turbines are machines which develop torque and shaft power as a result of momentum changes in the fluid that

The length-tension relationships represent an important part in the function of skeletal muscle. When skeletal muscle is stimulated‚ passive tissue rapidly changes into dynamic tissue which can produce force. Furthermore‚ during this process‚ the length of muscle may decrease‚ increase‚ or remain the same. Moreover‚ the amount of power a muscle can produce depends on its length‚ velocity and stimulation Powers & Howley (2015). Muscle velocity and stimulation are normally in a constant when creating
