The automotive mechanical and collision repair industries have always had changes over the years‚ requiring new diagnostic tools and new hand and air tools frequently. However‚ the newest upcoming changes may require a change in how technicians work on vehicles in addition to new diagnostic and repair tools and equipment. Vehicles no longer use only steel or fiberglass‚ so collision repair technicians must learn new skills‚ including welding aluminum and high strength steel. Almost all automotive

tetrasulfide. The collision theory briefly: For a reaction to occur particles have to collide with each other. Only a small percent result in a reaction. This is due to the energy barrier to overcome. Only particles with enough energy to overcome the barrier will react after colliding. The minimum energy that a particle must have to overcome the barrier is called the activation energy‚ or Ea. The size of this activation energy is different for different reactions. If the frequency of collisions is increased

take place‚ we use the collision theory. Collision Theory The collision theory states that for a reaction to take place between reacting particles (ions‚ molecules or atoms)‚ it is essential that they collide. B A B A The collision theory goes further to state that for a reaction to take place‚ there must be sufficient energy in the collision. If there isn’t sufficient energy‚ the colliding particles simply bounce off each other. Compound A-B formed when the collision has sufficient energy

tools that are required to solve typical convection heat transfer problems are presented. As engineers‚ we are most often interested in the interaction between a fluid and a surface; specifically the transport of momentum and energy between the surface and the fluid. The transport of momentum is related to the force exerted on the surface and it is

places extremely high stresses on the elbow and shoulder. In all throwing athletes‚ especially baseball pitchers‚ these high stresses are repeated many times and can lead to serious overuse injury. Unlike a small injury that results from a fall or collision with another player‚ an overuse injury occurs gradually over time. In many cases‚ overuse injuries develop when an athletic movement is repeated often during single periods of play‚ and when these periods of play‚ games or practices‚ are so frequent

The Stellar Lives of Stars Stars are giant nuclear reactors. In the center of stars‚ atoms are taken apart by tremendous atomic collisions altering the atomic structure and releasing an enormous amount of energy that makes stars hot and bright. Nuclear fusion is an atomic reaction that fuels stars. In fusion‚ many nuclei combine together to make a larger but different element‚ and the result of this process is the release of a lot of energy. Stars are powered by nuclear fusion in their cores
