I. LANDING GEAR SAFETY DEVICES Most airplanes with a retractable landing gear have a gear warning horn that will sound when the airplane is configured for landing and the landing gear is not down and locked. Normally‚ the horn is linked to the throttle or flap position‚ and/or the airspeed indicator so that when the airplane is below a certain airspeed‚configuration‚ or power setting with the gear retracted‚ the warning horn will sound. Accidental retraction of a landing gear may be prevented by

that hydraulic fracking is good for the environment because it puts toxic waste into the ground‚ contaminates water supplies and the accidental spills lead to much devastation‚ and even our groundwater gets contaminated. Toxic waste from the hydraulic fracking is one of the worst things that is happening as of right now. Fracturing fluid chemicals are known to cause cancer and they sometimes use the fracturing fluid for flowback. The flowback of fracturing enters the air easily. Hydraulic fracking

Hydraulic Fracking is a hot topic these days within the media of Ohio and locals of Licking County‚ Ohio. What issues and risk do we seem to currently need to be aware of? Could properties of local residents be affected and what step(s) are we taking to insure a brighter future for Ohio? Fracking‚ also known as‚ hydraulic fracturing is the idea of using hydraulic pumps mixed with water‚ sand‚ and chemicals to break rocks apart at high pressures which then will release gasses. The chemicals used

The concept is very similar to sudden expansion in pipe flow‚ except that hydraulic jumps occur in open-channel flow. At

Hydraulic fracking is the method of extracting gas from sediments by injecting the area with a mixture of water‚ sand and other chemicals to release methane gas. Another source of fuel is the mining of coal. Unlike fracking‚ coal mining requires labor that is both physically demanding and hazardous. Mining for coal also requires a larger surface area and therefore could have a larger negative impact on the environment. The burning of coal contributes more CO2 emissions than the burning of natural
