Sorry for the late reply i was waiting for my work to come back marked. Again i used the formula above and went with 1/6 or 0.166 as my answer and again its come back as incorrect. the diagram is definitely right (well what they have printed. This is ICS and have had quite a few errors in the...
Tiny-tim thanks for the hint. I have been looking at this problem again today and i believed the answer originally should have been 1/6 as the effort is 1m away from the fulcrum and the load 6m away from the fulcrum. This came back marked as incorrect though.
This is why i considered the 1/5...
Homework Statement
Calculate the velocity ratio of the attached lever.
Homework Equations
Velocity Ratio = Distance moved by effort * Distance moved by load
The Attempt at a Solution
Ok I'm having some confusion over this question. I cannot figure out whether the 'Distance...
Unfortunately not they do not specify the units of measure i believe that is part of the paper to test that you understand the difference between the units. I will review the course material AGAIN :rolleyes: to see if i can get an idea as to which units they are looking for. I really...
Tiny Tim Thanks for the break down i see i have my units of measure confused. Will have another look at it.
I have already confronted ICS with at least four errors in their course work. The tutor replies it's an error in the text and my workings seems to be right and they will look at it...
Homework Statement
Calculate the velocity ratio of the system.
Third Class Lever
Efficiency = 65%
Mechanical Advantage = 1/6
Work Put In 3000J
(I know if the system was theoretically 100% efficient the velocity ratio is 1/6 or 0.167)
Homework Equations
Velocity Ratio =...
Ok i need to put out an SOS call on this. I to am doing the ICS course and spend 10 hours + trying to translate the ICS language (Not going to good). I'm attempting the same question here. Read this thread over and over again. In simple terms could someone please give me a reason to live and...
Homework Statement
Calculate the centripetal force required to rotate a 3Kg object in a circle at a radius of 3m at one revolution per second?
Ok for some reason i find circular motion a real struggle i have come up with an answer for this question but looking for some reassurance i am on...
Hi,
I guess i worded this question wrong. Anyway have spend some more time on it and now have a slightly different question for this system. The force load is 200KG but as there is gravity acting on the crate will the force load be (200 x 9.81) making it 1962N rather than 200N?
I have now...
Homework Statement
The 200Kg Crates are placed on a hydraulic lifting beam: (Diagram attached)
A. State the order of lever used here
B. Calculate the effort required to lift the load
C. Calculate mechanical advantage for this system
D. Calculate the velocity ratio for this system. If the work...
Hi,
I have a simple question i am working a tension query and need to do some trig calculations. I know the equation i need is below.
θ = Sin^{}-1 0.6/3
When i type this in the calculator as shown above i get an answer of 12.29 although when i enter it in the calculator using brackets...
Hi thanks for the reply i see where i mixed my final equation up. I took a quick glance at my course material and they have written the equation back to front. I'm starting to seriously worry about the quality of the course materials with the errors i have come across so far.
Homework Statement
When the converyor belt was first installed safety checks were carried out to determine the limit of angle for safety. It was found that at an angle of 30 degrees the crates start to slip down.
Calculate the coefficient of friction between the crates and the belt? (Diagram...
Thanks for the reply. I see your point (why make life difficult! :D) i have just tried the force * time to work out the impulse and that confirms my answer for me. Thanks for the help
