How to calculate age of tree using ring without cutting

How to calculate age of tree using ring without cutting The rings in the trees are used to calculating the age of the trees and tells what the weather was like during each year of the tree’s life. The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall. One light ring plus one dark ring equals one year of the tree’s life. The color and width of tree rings can provide snapshots of past climate conditions. For example, tree rings usually grow wider in warm, wet years and they are thinner in years when it is cold and dry. If the tree has experienced stressful conditions, such as a drought, the tree might hardly grow at all in those years Calculating the age of the tree without cutting The age of the tree can be calculated without cutting the tree with the help of an instrument called Increment borer this instrument is bored into the tree up to the centre and ...

Why Auto-rickshaw tyres are tilted

Why Auto-rickshaw tyres are tilted Many times we saw auto tyres are tilted slightly about 1-3° vertical it is called Camber Camber is are three types 1.Positive Camber 2. Negative Camber 3.Neutral Camber When the auto-rickshaw is unloaded the tyres will look tilted when it is fully loaded with passengers the tyre inclination will become straight. It also help to withstand heavy load during traction and avoid tyre wearing during running Negative Camber are used in off-road vehicle like tractor
