Assuming mechanics is required, the following results were found.

  • Mechanical Advantage and Velocity Ratio

    Many parts of the body can be treated as parts of a lever if they involve a pivot at a joint. In general muscles apply forces - the effort - to the parts of a joint. This will result in a turning around the pivot and another force - the load - being...

  • Some Strange Implications of Quantum Mechanics

    Quantum m,echanics can have some very strange implications. A particle may be in several places at one. This is a consequence of the state of the particle being described by a wavefunction, with the probability of a particle being in a region of space...

  • The Connectin Between Kinetic Energy in Newtonian and Relativistic Mechanics

    In Newtonian mechanics, the momentum and kinetic energy are given by and The relationship between momentum p and kinetic energy is often written as Many equations and concepts in Newtonian mechanics have close analogies in special relativity. For...

  • Quantum Mechanical Operators

    and dymamics can be described with the deterministic equations of Newtonian physics. Part of the development of quantum mechanics is the establishment of the operators associated with the parameters needed to describe the system. Some of those operators...

  • Mechanical Determinism

    Newtonian mechanics is a complete system. Given a state of a system of particles and the mass, velocity and position of each particle, the state of the system – the position and velocity of each particle can be determined at any subsequent or previous...

  • Mechanical Problems With Second Order Differential Equations

    Many problems in mechanics gives rise to second order differential equations as a consequence of Newton's second law of motion, The acceleration a is actually the second differential of position with respect to time, so any problem involing...

  • Representing a Mechanical System in Matrix Form

    Consider two masses connected between two fixed blocks by three springs. Initially the system is in equilibrium and all the springs are in tension. The masses are given small pushes and start to vibrate. The net force on mass 1 is...

  • Mechanism of X - Ray Attenuatino

    When an X – ray hits a material, it generally penetrates the material and it's energy is gradually reduced as it passes through the matter. There are several mechanisms via which this may happen, summarised in the table below. Note that = attenuation...

  • The Mechanics of Atomic Spectra

    In an atom, electrons occupy orbits, each with a particular energy. The orbits and energies are specific to each element. This energy is negative because the electron and nucleus are oppositely charged, so attract each other and energy must be given to...

  • The Mechanism of Light Production by a Gas Discharge Tube

    Gas is normally not a good conductor of electricity. The molecules of the gas are electrically neutral and the gas contains very few ions. This means that in order for a gas to conduct electricity, a source of electrons is needed. In a gas discharge...

  • The Mechanism of Lightning Production

    Static electricity is commonly produced when insulating materials rub together. When fur is rubbed against an ebonite rod, the fur becomes negatively charged and the rod becomes positively charged. Electrons are transferred from one material to the rod...
