what is an easy and fast way to make a scarf?
need more infoHow are the gears connected? Are there cables and pulleys? What turns the gears, how are they connected to the load, how big are the pulleys, etc.
Dude - it is indeed this simpleThe four choices are for dummies - one sum, one subtraction, and two divisionsAnd, the word advantage implies that the number has to be greater than 1 - otherwise, what advantage? Now, this is just based on purely test-taking techniquesHowever, what is being asked is how much excess force (in an overly simplistic example, to be sure) you use to overcome the friction and propel the bike736N is roughly a 75 kg person pushing down on a lever - and, you are told that it takes only 81N to move it forward (again, tooooo simplistic)So, 736/81 9.08The problem is however not about a force, but about torque - force times distanceThat's why the term is crank for the larger (front) cogFollow upPal - I understand what you are telling meHowever, as I said, your little problem is way to simplisticYou only have two values - the force with which you push on the pedal and the friction force to overcomeSo, yeah - your teacher is ignorant, but, within the confines of the problem this straight ratio was his intentAs to the other comment of yours - your argument is about the gear ratio, not what you have to deal with in your problemSometimes, it is better not to overthinkCapisce? PSJust noticed - you are from CanadaAll bets are off nowDon't you guys have square wheels there?
I am about as handy with fabrics and fibers as a trapdoor in a canoe, but even I can make a scarf, striped or solid, with fringe, in about two hours using a Knifty KnitterIt's a loom approach to knitting, and when Michaels first started carrying them about 4-5 years ago, I had to demonstrate one without ever having even seen oneI read the directions, and was getting a little anxious about doing this in front of a store full of people, when my scrapbooking instructor popped in with her kidsWhen I explained my dilemma, she said that it was no problem, even her five year old son could make a hat in a couple of hoursNaturally, I said, well I think I'd like to SEE that.so she sent him out to get a skein of yarnHe came back with the ugliest ball of yarn in the whole store, sat down and proceeded to cast on and knit about a dozen rowsI figured if a five year old could do it, I had a pretty good chanceHats and tube scarves just go around and around.if you want a single weight flat scarf (which tends to curl, like any knitted item) you have to do rows, back and forthThe set of four looms comes with a tool, costs about $7-10, depending on whether or not it is on sale, and there is an excellent illustrated booklet for $1 It's a lot of fun, and also a great way to knit hats and scarves for charity by using up partial skeins.
