Acid-Base Reaction: Hydrochloric acid will react with potassium hydroxide to give potassium chloride and water. The net ionic equation for this acid-base reaction shows the formation of water from hydrogen cation and hydroxide anion.
Why is dynamic balancing needed?
The balancing of rotating bodies is important to avoid vibration. Dynamic and Static Balancing in Heavy Industrial machinery such as generators and motors can cause catastrophic failure, as well as noise and discomfort. To help with balancing, it involves simply moving the centre of gravity to the centre of rotation.
How is dynamic balancing done?
Dynamic balance refers to the way machines are balanced by rotating parts quickly and measuring the imbalance using electronic equipment. The imbalance measured can then be corrected by adding or subtracting weight from the rotating parts until the vibration is reduced.
What is dynamic wheel balancing?
Dynamic Balancing is when the wheel and tire are clamped on a machine and spun at speeds of approximately 10-15 mph or 55-60 mph. Sensors then pick up where the imbalance is on the tire as it rotates as well as where counterbalances should be placed. Dynamic Balancing picks up on both static and dynamic imbalances.
What is the difference between internal balancing and external balancing?
Internally balance engines have weights added to the crankshaft counterweights to achieve proper balance in the rotating assembly. To achieve proper balance in the rotating assembly, externally balanced engines require the use of added weight to the flywheel/flexplate, or weight removed from one side of the flywheel.
What happens when a harmonic balancer fails?
If the harmonic balancer gets too old or fails and can no longer properly absorb the harmonic vibrations, the engine will shake excessively. The shaking will become even more pronounced, and therefore dangerous to the engine at high speeds.
