Gear trains transmit power from an input shaft to an output shaft using a combination of gears. They are used when the input and output shafts need to be oriented spatially or when there is a large difference between input and output speeds. There are three main types of gear trains: simple, compound, and epicyclic. Simple gear trains have one gear per shaft and the input-output speed ratio depends only on the gear teeth. Compound gear trains can have multiple gears per shaft, and the speed ratio depends on all the gear teeth. Epicyclic gear trains have gears mounted on moving shafts relative to a fixed axis, allowing at least one gear axis to rotate relative to the frame.
The fundamental law of gearing states that for a pair of gears to transmit a constant angular velocity ratio, the tooth profiles must be designed such that the common normal or line of action passes through a fixed pitch point on the line connecting the gear centers. This ensures the gears maintain the proper rotation and speed ratio as they mesh and turn.
Gears are toothed wheels that transmit constant angular velocity between two shafts, which can be parallel, intersecting, or non-intersecting. There are different types of gears classified by the orientation of their shafts, including spur gears which have radially arranged teeth parallel to the shaft allowing transmission between parallel axes, helical gears which have teeth arranged at an angle to the axis, and bevel gears which connect intersecting shafts. For gears to maintain a constant speed ratio, their tooth profiles must be designed so that the line of action passes through a fixed pitch point along the line connecting their centers.

Centrifugal pumps in series and parallelphysics101
Centrifugal pumps work by using a rotating impeller to increase the velocity of a liquid and discharge it out of the pump housing. They have advantages like being simple, compact, and able to handle high rpm, but disadvantages like poor suction power and needing multiple stages to increase pressure. Proper installation requires a tight suction line, independently supported piping, minimal fittings, and protection against air intake to optimize performance. Pumps can be arranged in series to increase total head or in parallel to increase overall flow rate.
Laminar and turbulent flow can be distinguished by observing dye injected into a flowing fluid. Laminar flow moves in parallel, undisrupted layers while turbulent flow is disorganized with eddies. The Reynolds number determines whether flow is laminar or turbulent based on velocity, diameter, density and viscosity. Laminar flow has Re ≤ 2000 while turbulent flow has Re ≥ 3000. Viscosity resists flow and decreases with temperature for liquids but increases for gases.
The document summarizes the main engine systems, including the starting system, charging system, ignition system, and lighting system that make up the electrical system. It also describes the fuel system that supplies air and fuel mixtures, and can use a carburetor, petrol injection, or diesel injection.

The document discusses calorimetry and specific heat. [1] Calorimetry is used to measure heat changes in chemical and physical processes using a calorimeter, which is an insulated device that measures heat absorption or release. [2] Specific heat is the amount of heat needed to change the temperature of 1 gram of a substance by 1 degree Celsius or Kelvin and is measured in Joules per gram-degree. [3] An example calculation is shown to determine the specific heat of copper using calorimetry data.
The document discusses flash point and fire point, which are measurements of the lowest temperatures at which lubricant vapors will ignite (flash point) or sustain combustion (fire point). The flash point indicates transportation and storage requirements, while a significantly lower flash point than normal may indicate contamination. The fire point is usually 8-10% higher than the flash point. The document also lists equipment needed to test flash point and fire point, including an open oil tester, thermometers, and oils of different weights.
The document discusses the calibration of pressure gauges using a dead weight tester. A dead weight tester compares the readings of the gauge being calibrated to a standard gauge using an incompressible fluid and weights to apply precise pressures. Factors like friction, lost motion, and hysteresis can cause inaccuracies that calibration corrects. The pressure produced is calculated using the force applied by the weights divided by the area of the piston.
This document provides guidance on handling hazardous substances in the workplace. It states that hazardous substances have the potential to harm health or safety and should be stored separately from non-hazardous substances in undamaged containers. Employees should receive instruction on the safe handling, storage, and clean up of spills of hazardous substances, as well as first aid treatment if exposure occurs. References for further information are also provided.
Hazard communication involves communicating chemical hazards to employees through labels, material safety data sheets (MSDS), and training. Key aspects of hazard communication include identifying chemical hazards using labels on containers and MSDS sheets, which provide information on safe handling, health effects, and emergency procedures. It is everyone's responsibility to safely handle chemicals and understand this hazard information.
The document outlines the key steps of the scientific method, which include making an observation, forming a hypothesis, performing an experiment to test the hypothesis, collecting and analyzing data, drawing conclusions, and communicating results.
