Question

The product second moment of area Ixy is found by multiplying Ix and Iy. a)True b)- False

Answer 1

(b)False

Step-by-step explanation:

`I_(xy)` defined as

`I_(xy)` =
`\int \left (x\cdot y\right )dA`

Where x is the distance from centroidal x-axis

y is the distance from centroidal y-axis

dA is the elemental area.

The product of x and y can be positive or negative ,so the value of
`I_(xy)` can be positive as well as negative .

So from the above expressions we can say that the product of
`I_(x),I_y` is different from
`I_(xy)` .
