A bicycle is a physical system because there are several parts which work together to perform a function.
What are examples of physical systems?
An atom or the water in a lake can both be considered as physical systems.
Some examples are:
- the Earth’s atmosphere.
- a falling object.
- a hydraulic pump.
- the wing of an airplane.
- a glass of water.
- a crystal or other solids.
- the nucleus of an atom.
- fundamental particles like quarks.
What is a bicycle system?
Bicycle drivetrain systems are used to transmit power on bicycles, tricycles, quadracycles, unicycles, or other human-powered vehicles from the riders to the drive wheels. Most also include some type of a mechanism to convert speed and torque via gear ratios.
What are human made physical systems?
Human-made physical systems include mechanical systems, optical systems, electrical systems, and combinations of these. The names of these systems come from the type of energy they use.
What type of energy is riding a bike?
Bicycling is a rich source of kinetic energy.
What are the five physical systems?
What are the 5 systems of the physical world? The five systems of Earth (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) interact to produce the environments we are familiar with.
Is a computer a physical system?
A ‘computer’ is a physical system with actual constituent parts and its own internal interactions that take it from one physical state to another.
What is a bike drivetrain?
The ‘drivetrain’ of the bike consists of all the bits that you use to push (or pull) the bike along. The key components are the pedals, cranks, chainrings, chain, cogs (cassette) and derailleur.
What are the input and output of a bicycle system?
The input is what you put into a bicycle when you ride it. It is the pedalling force and the pedalling speed. In the process box in the middle is the bicycle. The chain drive of the bicycle changes the input pedalling force and pedalling speed into an output.
What is cassette bike?
A bicycle cassette is the cluster of sprockets located on the rear hub of your bike, slotting onto a freehub body and held firmly in place with a threaded cassette lockring. A typical cassette can have anything between five and 13 sprockets, although most modern bicycle drivetrains use either 9, 10 or 11.
