I picked this bit of trivia up on NPR radio yesterday, no fair going to the website to look up the answer.
1st question- what is it in hardwood trees that make them hard.

something to do with the grain.
and whatever it is, balsa wood has it, and falls into the hardwood catagory.

I'd say it's the stacking of the dead wood cells (Xylem, I believe?) Either that, or the water in the live cells (Phloem?). |
Xylem and phloem are actually "veins", as it were.. I think - they move water and minerals up from the root to the leaves and the flower/fruits.

skeletor has the funniest answer for sure, but no cigar guys.. keep working on it.. but the answer is, its much more basic than you might think. think "food"
second question: you have a trailer connected to your vehicle, you are traveling, the direction is unimportant, in that you could be backing up as well and the answer is the same.. "the question is, are you pulling, or pushing that trailer?"

Pulling sounds too simple, so I'll go for pushing ![]()


You're pushing it. When the trailer is going forward, tacked onto the behind - the small "plug" that goes in the hook is attached to the car, and is the moving force. It pushes against the hook, pushing the trailer forward.. i think...
in fact wait, i'm beginning to doubt myself orph, is this a trick? ![]()

no, no trick, you are in deed pushing it, no matter the direction, a better terminology would be towing the trailer, instead of the more common term "pulling it"
you are pushing cause, the hook is in front of the ball its attached to.
now if you guys could tackle the hardwood tree's ![]()


wildcard, the question was already answered, you are incorrect.. sorry.
re-read both mine and gwils answer.
direction of travel is not relevant

but the car is in front of the hook......

*sighs and breaks out pen and paper to draw stick figures*
in order to be "pushing something, the driving force must be behind it, hence the ball is behind the hook, the direction of travel not withstanding, the ball will still remain behind the hook..
i cannot make that any simpler.. i am sorry if it still is unclear, maybe some of our college attendee's can do it ![]()
bottom-line, you are pushing, not pulling.
[addsig]
yea but you dont need the hook
Isnt it just for safety?
