Homework Statement

A bucket filled with water has a mass of 86.5 kg and is attached to a rope that is wound around a 0.44 m radius cylinder. What torque does the bucket produce around the center of the cylinder?

Homework Equations

I=2/5 mr^2
w=v/r
mgh=1/2 mv^2+1/2lw^2

The Attempt at a Solution

i=2/5mr^2
i=2/5 3.69*.154^2=.035004816

w=square root 2*3.69*9.81*1.85/ 3.69*(.154^2+.035)=24.84951169
v=wr=24.84951169*.154=3.828776764

the worksheets online. it kepps telling me its wrong. and i tried rounding.

The question is asking for torque and you are finding velocity.

What is the definition of torque?

oh. thanks i got it now.
T=mgd=86.5*9.81*.44=373.37N*m
