Question

Moment of inertia of a unifrom circular disc about the tangential axis parallel to its diameter

Answer 1

Answer:

by perpendicular axis theorem

$i2 = ix + iy \\ mr2 = 2ix \\ ix = mr2 upon2 \\ by \: parallel \: axis \: theorem \\ ik = iy + ma2 \\ mr2 \: upon2 + mr2 \\ 3 \: upon \: 2 \: mr2$

Explanation:

u can understand it upon means 2 numbers one upon down if u feel it's correct so mark me as a brainliest

Answer 2

Answer:5mr^2/4

Explanation:

Moment of inertia=mr^2/2. Moment of inertia in parallel axis mr^2/4. Moment of inertia. Tangent along parallel axis mr^2/4+mr^2=5mr^2/4
