Sorry the picture is so small. I guess you can download it and then zoom in or something. The main question I'm interested in 2b. Calculating the moment.
position of neutral axis: 37.14mm
Second moment of area: 2.83 x 10^(-6)Homework...
Thanks. The thing is, there's no mention of this in our coursebook, and because our lecturers are old men, they don't check their emails. So you'll forgive me if I don't take your answer unless you're absolutely certain
----EDIT----
The lecturer just released the answers. You were right after...
Homework Statement
Why does an IC engine generate about the same maximum torque over a range of engine speeds but the maximum power at only one speed?

None.
The Attempt at a Solution
For max power, the best I can come up with is that since torque does not drop as...
Hey one more question about the second moment of area. How do you find it for any shape and about any axis? I'm still rather confused about the integral thing and it'd be helpful if someone went through the process of getting the second moment of area step by step.
Thanks.
That's not particularly descriptive.
And also, the definition of the second moment of area is I_{yy}=\int_A z^2 \, dA
But why is the lower limit of intergration A, and there is no upper limit?
Hi I'm a second year uni student and we're learning the engineering beam theory, and part of the engineering beam theory requires us to know what the second moment of area is. I've scrawled wiki and the internet but I haven't found anything very helpful.
So my question is, what exactly is...
