Physics While Gardening

Source: wired.com

It was a nice warm day and the trees need trimming. I found that pruning before all the foliage begins to sprout, pruning is easier. With out all the leaves, you can see the branches the have died or the ones that need trimming. Another good thing is the weather is not sweltering yet.

If you’re like me, when you see a thick branch you cringe. Your choices are to get off the ladder and go for the saw or grin and bear the extra effort you’ll need to squeeze the lopper handles very hard. At some thickness, I will fall back to the saw.

The diameters in between are where physics may come in handy. The loppers like scissors are just levers with a pivot point. Some of the obvious things to look at before getting into hard core pruning is the sharpness of the cutting blade and making sure the pivot point is oiled. Both of these will provide you with a tool that will slice through the branch easier and make a cleaner cut.

Some things can’t be rectified by maintenance, these are termed obsolescence. These things can only be solved by buying the new state of the art lopper and if you are like me the loppers you are replacing are 15 to 20 years old.

The things you should look for are thin cutting blades as the thicker these are the more resistance they will have when slicing through the branch. The length of the handles are important because the longer they are (within reason) the more leverage they provide making the effort you exert less. The less force you need to apply will also help cut down on the blisters you get. Lastly, some loppers have multiple pivots, these are designed to increase the leverage.
