Before The Trunk Of A Large Tree Felled: Before The Trunk Of A Large Tree Felled (by Amish Fathers) This is an awesome book by William Ollestad. Before The Trunk Of A Large Tree Felled is a journey to the land of long-lasting beauty. It takes us back in time to the story of the tree of life, which is the American Chestnut. In the book, William Ollestad narrates the sad story of an American Chestnut called the Old Trees. He takes us back in time to the year 1776 when a British Captain locked the Old Trees in his ship and left them to starve to death.
The story is full of hardship, grief, love and wisdom. In the end it makes you think that the strength of trees is indeed legendary. We know that they have been around since ages but what is amazing is that they have survived such things as bullets, fire, earthquakes and even a nuclear war. Before The Trunk Of A Large Tree Felled, William Ollestad shows us the process of felling a tree, explaining how the forces which cause the death of a tree work on a tree. It is amazing that a mere pencil could cause such a massive death.
Let us now look at problem number two, which is what happens to a tree when it is chopped down. Problem number one was about the cables and problem number two is about the tree. The story is full of sorrow but it is also full of hope. We know that trees can live and be healthy even when there is an environmental catastrophe but we do not know for sure how long they will be able to stand.
Problem number three is related to the question of knowing what happens if the tree is felled even before the cables are attached. This problem has an answer because the force of acceleration due to the falling tree is equal to the force due to the pulling of the cable. In physics this is known as conservation of energy. The moment the tree falls the acceleration due to gravity will be equal to the moment about o of the resultant force exerted on the tree by the cable.
Problem number four concerns the manner in which we manage to maintain a balance when we pull a string. If we pull a string that has a length as long as the diagonal of the cable, the moment about which the cable is drawn will be equal to the moment about o of the induced force due to the pulling of the string. If we know that the length of the string needs to be as long as the diagonal of the cable, we can solve the problem by knowing that the moment about which the string is pulled is equal to the sum of the moments about which the cable is pulled. Therefore knowing what happens when a large tree is felled we can solve problems one by one and this is what happens when trees are felled.
