Q and A 24623 by Mr G needed information substituted by KR IRS
Q1 Tire tread is another important development in tire evolution. The tire tread is the part of the tire that actually meets the road. The elements of tire tread include tread blocks or tread lugs, tread grooves, tread voids, wear bar, and any extra features such as a rain grooves and siping. Tire tread spans the entire surface of the tire from shoulder to shoulder where the tread approaches the sidewall. The areas between the tread blocks are referred to as the tread voids or tread grooves. Tread voids provide the tire with traction by enabling the tread blocks to move and flex as the tires to grip the road. They also allow the water to escape when roadways are wet. Tires with a high tread to void ratio provide better wet traction and braking ability. Just as vehicles are engineered with a particular type of performance in mind, there are specific tread types and patterns that match each kind of intended performance. Tire tread is helps vehicles to corner tighter, accelerate more smoothly, and brake reliably. Tire tread is also capable of helping to maximize fuel economy. Many think of a tire tread as the knobs or shapes that can be easily seen on the part of the tire that comes in contact with the road. Tire tread actually consists of several components including the shape of the tire, the tread blocks (also known as tread lugs), the tread grooves, tread voids, wear bar, and any extra features such as rain grooves and sipes. Tire tread is capable of allowing vehicles to corner tighter, accelerate smoother, and brake quickly. Tire tread is also capable of helping to maximize fuel economy. One of the most obvious benefits of specialized tire tread is in the use of off-road vehicles. Everything from Jeeps to 4x4 trucks, as well as heavy machinery such as tractors, use off-road, or all-terrain, tires. The tread is designed to work over any ground surface, whether rocky, wet, or covered in mud. Hence tread for this and that is not a proper reasoning. GRIP THAT MATTERS. Treads are that of the manufacturers’ designs. Q6 The Q sounds like FRUCTOSE AND NON-FRUCTOSE FRUITS. Absurd Q. No fruits except acai the least fructose fruit and the following bear the least fructose like: Strawberries. Strawberries, like many other berries, are often high in fibre and contain very little sugar. Peaches. Blackberries. ... Lemons and limes. ... Honeydew melon. ... Oranges. ... Grapefruit. ...Avocados. Thus, Q and A is a waste.

This means that the pilot has to use more > runway than normal, which may limit the choice of airports or runways > available and the pilot has less margin for error or aborting the takeoff > or landing. > > Also without flaps, the aircraft has a different pitch attitude (nose up > or down angle) during takeoff and landing than normal. Hence the pilot > has to adjust their sight picture and their control inputs accordingly and > the aircraft has less ground clearance during takeoff and landing, which > may increase the risk of tail strike or propeller strike. > > *All the above QA are from Quora website on 24-06- 2023.* > > *Quora answers need not be 100% correct answers .* > > *Compiled **and posted by R.
