Because it isn't explicitly mentioned in the spec, it won't be in most textbooks. This is an application of your current knowledge of springs, so they can ask it in the exam.

Quick question with solving the equation 1/kt = 1/k + 1/2k Why not solve it how you solve other fractions in mathematics, simply by making the 1/k an equivalent fraction like so: 1/kt = 2/2k +1/2k 1/kt = 3/2k Then invert both sides: kt = 2k/3 Extremely useful video though, I missed the lessons where springs were explained so this made for some much needed catch up revision.

@victoriacorcimaru17312 жыл бұрын
Thank you so much! I've been trying to understand this for quite a while! One quick question, how can you explain this difference in the spring constant using Young's modulus?
@qvixfy8529 Жыл бұрын
I think since young modulus of a material is directly proportional to its stiffness or constant K, you can say that for two springs in a series arrangement the young modulus decreases relative than to that of one spring since the stress over strain ratio of both two springs in series decreases and the opposite will be true for a parallel arrangement. So i guess the answer to your question would be that since the stress over strain ratio ( young modulus) decreases of a series arrangement relative to one of its spring, the constant K will also decrease as young modulus and K are directly proportional

Thank you Sir, these videos are helping me alot. If you don't mind can you please explain a few things to me. 1:45 Why is the spring constant halved, when the same amount of force is applied? Is it because the force is shared between the two springs? Say they were 4 springs in parralel, would that mean that the spring constant is 1/4?

How come you cannot solve the equation like this: 1/k(total) = 1/k + 1/2k k(total) = 1/(1/k + 1/2k) k(total) = k/1 + 2k/1 k(total) = k + 2k k(total) = 3k

Matt Whitelock Does 1/(1+2) = 1/1 + 1/2 or does it equal 1/3?
@mattwhitelock47257 жыл бұрын
That makes sense, but I'm still confused to the actual reasons for this - if you raise something to the power of -1, you flip the fraction, right? So why can't you just raise both sides of the 1/k(total) equation to the power of -1, and get k(total) = k + 2k?
@afc89817 жыл бұрын
Matt Whitelock 1/(a + b) DOES NOT equal 1/a + 1/b. Therefore 1/(1/k + 1/2k) doesn't equal 1/(1/k) + 1/(1/2k). This is wrong. You need do this: 1/(1/k + 1/2k) = 1/(2/2k +1/2k) = 1/(3/2k) Now you can flip it to get 3k/2 or 1.5k.
