Answer:
Explanation:
information we have:
mass:
lenght:
frequency:
time:
and from the information we have we can calculate the angular velocity . which is defined as
----------------------------
Now, to calculate the torque
We use the formula
where is the moment of inertia and
is the angular acceleration
moment of inertia of a uniform rod about the end of it:
substituting known values:
for the torque we also need the acceleration which is defined as:
susbtituting known values:
and finally we substitute and
into the torque equation
:
