GEARBOX DESIGN PROJECT DESCRIPTION You are the designer and you have been asked to design a speed reducer that will take power from the shaft of an electric motor rotating at 1500 rpm and deliver it to a machine that is to operate at approximately 750 rpm. Assume that you have decided to use spur gears to transmit the power and you are proposing to use a single-reduction speed reducer. The power to be transmitted by the shaft is 20 KW and the input shaft is coupled to the motor shaft

The Effect of Temperature on Solubility By Aviraj Singh Rogers 2 Background: The solubility of most solid substances is generally said to increase as the temperature of the solvent increases. However‚ some substances‚ such as ytterbium sulfate‚ do the opposite. This can be explained through the Second Law of Thermodynamics which states that “in all energy exchanges‚ if no energy enters or leaves the system‚ the potential energy of the state will always be less than that of the initial state”

Land Speed Record The land speed record (or absolute land speed record) is the highest speed achieved by a wheeled vehicle on land. There is no single body for validation and regulation; in practice the Category C ("Special Vehicles") flying start regulations are used‚ officiated by regional or national organizations under the auspices of the Fédération Internationale de l ’Automobile. The record is standardized as the speed over a course of fixed length‚ averaged over two runs (commonly called

Biology A - Assignment 1: Cell Membranes and Temperature Background Theory Beetroot contains betalain pigments within it’s vacuole‚ which gives it it’s purple-red colour‚ it’s this pigment which leaks out as the beetroot is heated and the cells membrane begins to break down. The practicals aim is to show the effect of temperature on the cell membrane by observing the colour change of the water the beetroot was placed in. The cell membrane is important as it controls the substances enters and
