Hand Truck

A hand truck, also known as a two wheeler, stack truck, trolley, trundler, box cart, trolley truck, sack barrow, sack truck, dolly, folding nose trolley or bag barrow, is an L-shaped object-moving handcart with handles at one end, wheels at the base, with a small ledge to set objects on, flat against the floor when the hand-truck is upright. The objects to be moved are tilted forward, the ledge is inserted underneath them, and the objects allowed to tilt back and rest on the ledge. Then the truck and object are tilted backward until the weight is balanced over the large wheels, making otherwise bulky and heavy objects easier to move.

Sack Trucks were originally used on  docks to move large sacks of spices back in the 1700s by young boys, from the age of 11, who were unable to lift the large sacks of spices by hand. By using this method they were able to work as well as grown men in moving items around.

Grigg-Putnam Index

The Griggs-Putnam Index is one of several empirical methods of estimating the prevailing wind speed at a site by observing the growth patterns of trees. Strong winds will deform trees and shrubs so that they indicate an integrated record of the local wind speeds during their lives

IBrushing occurs when small branches bends downwards.
II-III-IVFlagging occurs when large branches bends downwards, and branches which are upwind are shorter than branches which are downwind.
V-VIThrowing occurs when the actual trunk of the tree curves downwind.
VIICarpeting occurs when the trunk grows along the ground.

Thigmomorphogenesis is the response by plants to mechanical sensation ( wind, raindrops, rubbing by passing animals, etc ) by altering their growth patterns, which may include their canopy structure, growth rate, anatomy, morphology and mechanical strength of their wood. 

Thigmotropism is a movement in which a plant moves or grows in response to touch or contact stimuli, such as wall, pot, or trellis, etc.

Thigmonasty or seismonasty is the nastic response of a plant to touch or vibration.

Thigmotaxis is the movement of an organism toward or away from objects that provide a mechanical stimulus.
