Second moment of area about an axis along any diameter in the plane of the cross section (i.e. x-x, y-y) is each equal to (1/4)pi r^4.
The second moment of area about the zz-axis (along the axis of the cylinder) is the sum of the two, namely (1/2)pi r^4.
The derivation is by integration of the following:
int int y^2 dA
over the area of the cross section, and can be found in any book on mechanics of materials.
Answer:
cos210=cos(180+30)=−cos30=−√32 . sin210=sin(180+30)=−sin30=−12 . 3(cos210+isin210) =3(−√32)+3i(−12). −(32)√3−(32)i. My favourite way of seeing that sin30=12 and cos30=√32 is ...
Step-by-step explanation:
But that's what I say personally
The computation shows that there are 8640 combinations.
<h3>How to compute the value?</h3>
From the information, we are to find the combination when he rolls a cube that has six sides labeled 1 to 6, spins a spinner with three equal-sized sections labeled Walk, Run, Stop, and flips a coin.
This will be:
Cube = 6
Spinner = 3
Coin = 2
The combination will be:
= 6! × 3! × 2!
= 8640 ways
Therefore there are 8640 combinations.
