Moving Day

If you have to move a huge upright freezer on a small hand truck; and you come to a step up: You would rather pull the freezer up the step than push it, you should see how your effort is used in 2 directions as many things do with motion force; and how pushing from above the axle to roll over a step axle high or better, wastes some of your energy.

Pushing force into the lower axle, with weight of freezer pushing down, redirects some of your effort into the ground as freezer pushes down on axle. But if you pull, that redirection of the ‘lost’ force is up (depending on angle you pull axle from/ obstruction i think), that isn’t applied pulling forward. So understanding the simple mechanics and applying them, tapping into them can easily grant wider safety margin (SWL); as well as lessen fatigue (also a type of SWL IMLHO). The more weight, incline, tire deformation or ground imperfections the more noticeable the effect is that when you are higher than the axle, you are pushing into the ground or pulling out of the hole. When pulling a wheelbarrow you might be uncomfortable, unable to see etc. and opt to push, but it would cost ya…

If there was 500# of meat inside the freezer, you’d like it low center. If it was high left, and small hand truck was a bit to right, the load would be off balance, on the cross axis (perpendicular either direction) from the direction of travel; you might spend 30-70% of your effort fighting that off balance every step of the way, especially when compounded with other imperfections in the flow of the motion. Making a riskier trip with more effort. Then push into the step; and you’ll be ready to go home a lot sooner than the guy/girl placing handtruck axle/ pivot right under the C.o.B. and pulling up the step………., even pulling at right angle to maximize pull at step, throwing force through the tough part etc. If there is an off balance, especially leveraged high from axle/ pivot, you’d like it to be in the direction of desired travel; if not at least on the same axis as travel, not off balanced to the side, especially high weight.

Orrrrrrrr something like that!

Frankly after my last move... I'll just hire a darn mover. Ya never know how much crap you have until you have to pack it all.

i know what ya mean.......

Now if the cart was heavy, we might be able to bind the light side of freezer to the cart itself to anchor the off balance by off setting it….. Then we could move the the large freezer easily, as long as the leverage of pull to the side, didn't ovewhelm the weight/leverage of cart (wider giving more leverage to offside pull).

To me moving an off balance tree forward on the hinge/ pivot, is liken that high-off balance, heavy box. Only there are different ways to adjust it’s balance, than moving the handtruck, but ya still gotta size up the task and apply yourself to the pivot, leverage, C.o.B.. So if you can set the situation where you don’t fight the imbalance perpendicular to travel simply, you can pull over a tree with less effort, less load on line, testing/taxing all systems of that less. Like a wider SWL from invoking mechanics. If the imbalance is extreme you don’t have to put all the load of that on the hinge, but it can carry it’s share; taking that load/ sharing it from some other strategy/s (line, wedge, dutchman etc.). The pull line doesn’t have to fight the whole imbalance, I’m not saying every time a tapered hinge has to neither etc.

It just seems right to me in all examples of motion, in all fields to balance that way (tree); especially when finessing such leveraged mass that could wipe out the whole job or it's participants in one move. i reaaly can't think of anything else of any size that you try to move unbalanced, nor anything that will balance the pulls the full travel on the hinge, than the hinge itself.

If you have an offside lean, on a straight strip hinge, the leveraged arc of the lean weakens that tree's hinge jsut the same as bending a line does (only tree fibre is stiffer, therefore weakens more i think). For both arc over fibre and place the most leveraged control and load on the farthest out fibres, by isolating the load to them, as they are the tightest fibre, and as in 2 lines lowering, the tighter will carry more of the load.

The differance is that, with a line, we can't reshape it, increase it's volume of fibre support etc., we can't rearrange the pattern of the fibre at flexing, so that there are more fibres in the leveraged/loaded area of the fibre pattern. It is a fixed round shape, by dictation of it's manufacturer and use.

The craftsman that holds the saw,and patterns the hinge to carry the load with more fibre in the leveraged/loaded part of the arc, has the choice to fortify, instead of weaken on arcing fibre. By simply slanting the saw, we can schedule more fibre to the leveraged/working position, such as can not be done to maintain strength in the fixed shape of a line under similar arc.

Also, in addition to being more up to the pull of the task (better SWL), it also in this state is balancing the motion to it's axis of travel, and slapping the faces evenly to throw forward as squarely as possible into the face.

There are many choices, pulling with high leverage power, as anything else imbues power or speed. If too much of hinge is released, that power shows as speed. If just barely hairs from enough hinge is taken, that high leverage pulling power shows up as forced hinge power. Giving more strength to hinge, and strenghtening whatever pattern properties you programmed it with.

With tree work, everyday is moving day!
