A 30kg uniform solid cylinder has a radius of 0.18m. if the cylinder accelerates at 0.023 rad/s^2 as it rotates about an axis th

Nuetrik [128]

Answer:

0.011 N-m

Explanation:

Given that

The mass of a solid cylinder, m = 30 kg

The radius of the cylinder, r = 0.18 m

The acceleration of the cylinder, $\alpha =0.023\ rad/s^2$

It rotates about an axis through its center. We need to find the torque acting on the cylinder. The formula for the torque is given by :

$\tau=I\alpha$

Where

I is the moment of inertia of the cylinder,

For cylinder,

$I=\dfrac{mr^2}{2}$

So,

$\tau=\dfrac{mr^2\alpha }{2}\\\\\tau=\dfrac{30\times (0.18)^2\times 0.023 }{2}\\\\\tau=0.011\ N-m$

So, the required torque on the cylinder is 0.011 N-m.

What are the effects of overpopulation on a specific species in an ecosystem?

bagirrra123 [75]

Tere would be too many so there would be more fighting. Thye could overpopulate the world and destroy our stuff for example if it is a pig they can easily destory crops. We would all have to go hunting. There would also be less food so that is why they would start going out and destroying stuff.
