Thanks Fred... can you tell me how does one arrive at the value concentrated load of 67.5? I know with a uniform load we have to multiply the uniform load and the length it affects. eg: 2k/ft x 6ft

Hi all, I'm taking a Structures course in University and are learning about Freebody diagrams and figuring out Reaction forces (magnitude, direction, sense etc) and have a very basic question. Can someone please tell me how to convert a uniformly varying load into a concentrated point...

^^^ thank you so much my friend. That clears up a lot of questions. Now I'm off to try the questions :smile:

thanks I understand that. It seems like we are working backwards. Usually I get an equation in this form (3 - 1) k and I end up with 3k-k = 2k I've never had to take 2k and end up with (3-1)k confuses me here. sorry for all the trouble but why are we making 2k into (3-1)K ? Aren't...

GOOD LUCK! to you Alias25

this is the step that confuses me. Why do we add and subtrack k in the numerator? ok you say so that we get 3k. Why and how do we know we need to get 3k? thnx for the thorough explanation

here's where I'm confused. how did k ^ 3 + 3k ^ 2 + 2k end up to k ^ 3 + 3 k ^ 2 + 3k - k aren't we supposed to find the greatest common factor here? what step did you use in here?

^ sorry I don't quite get you. Where did the 0=k-k come from? How do I know I need to add 0 to the numerator?

help needed urgently: Basic Math Induction I am trying to teach myself mathematical induction, have never encountered this before and it's giving me trouble. My problem will likely be very easy to you all so please forgive me. I have put up the scanned image of the example in my book...

Hi, I am a 19 year old student from Canada. I have been given a conditional admission to an Architecture program at a local university. The problem is I need to complete the grade 12 (pre-university) Algebra and Geometry course, with a grade of 75+ in about 4 weeks. As you know may know...

I get answers that are very very close. .625 for the first formula and .631 with the second formula

Hi I'm doing a lab report on centripetal acceleration and we are asked to find the centripetal acceleration using 2 formulas. (1)Acceleration Centripetal=Force Centripetal/Mass (2)Acceleration Centripetal=Velocity^2/Radius I get answers that are very close but I also have to answer the...

Hi, I'm taking grade 12 physics atm and having a bit of a problem. The textbook we are using is also very old... published during 1980 so its very hard for me to try and learn by myself. My teacher is not helping much because in class many students end up helping the teacher solve the...

thnks Ambitwistor for the explanation :) I have never tried any problems like this before. I shall work it out now. :smile:

Hi, I've spent a long time and wasted lots of paper on this question. It might be very easy to do but I have tried/used every one of the motion formulas and don't seem to get a right answer. This is one of those challenge question that our teacher has given us. He hasn't worked out the answer...
