Hitchcraft for hammock tensioning

[mataharihiker]

There is nothing like a thread with math, engineering and gadgets to get me all warm and tingly...I just finished reading all 12 pages, believe it or not...I love people who know what they're talking about...I have bad hands, as soon as I get my Clark NA and see the rope diameter, I'm ordering one of hitchman's pulley's...after all, you only need to use one so the weight is insignificant...I weigh 110 so I couldn't break one if I tried....

Talking about that stuff get me warm and tingly... But designing things makes me REALLY happy.

Since we are talking math check out this equation:
a = b
ab = b2
ab – a2 = b2 – a2
a(a – b) = (a + b)(a – b) [(a - b) on both sides cancel each other out]
a = a + b [remember that a = b]
a = a + a
a = 2a
1= 2

Since we are talking math check out this equation:
a = b
ab = b2
ab – a2 = b2 – a2
a(a – b) = (a + b)(a – b) [(a - b) on both sides cancel each other out]
a = a + b [remember that a = b]
a = a + a
a = 2a
1= 2

oh my. If Sister Mary Augustine catches you dividing by zero she'll whack your knuckles with a ruler. Hurts, 'cause its made of cast iron!

I don't see how you got from ab – a² to a(a – b) since subtraction isn't commutative [not same as a(b – a)].

multiplied both sides of the equation by -1

then risked incurring SMA's wrath and wruler.

Sister Mary Augustine? That's not wrath, she just loves inflicting pain... pain is weakness leaving the body.

Sorry, I must have been thinking of 'the Penguin', Sister Mary Stigmata, of Blues Brothers fame. Let's get back to the math.

Nobody should ever apologize for invoking a Blues Brothers reference!
