To solve this you need to remember both torque equations
T = r F
and
T =(I) (alpha)
since the force of the string does not pass through the center of
mass, there is a net torque. So set the two equations equal to each
other and plug in the given variables
r = 0.1m
F = 1 N
I = 0.02 kg m^2/s
r F = I alpha
0.1 x 1 = 0.02 x (alpha)
5 rad/s^2 = alpha

A light string is wrapped
around the outside of a 2.0-kg-wheel whose radius is 75 cm. The
wheel has a frictionless axel that allows it to rotate but prevents
its center of mass from moving. Assume the moment of inertia of the
wheel is the same as that of a point particle of equal mass at the
same radius from the axel. The string is then attached to a 3.0-kg
hanging mass that is released from rest. While the mass...

about a horizontal axis. The string then goes
vertically straight up and over a massive
pulley that also rotates about a horizontal
axis, and finally connects to a mass m =
0.900 kg on a rough incline (μk = 0.200) that
is angled at 25.0° to the horizontal.

A cylinder of radius 0.40 m and a mass of 12 kg has a string wound around it. The string is pulled off perpendicular to the radius, so that it doesn't slip while spooling off the cylinder, making the cylinder rotate around an axis through its center with a rotational acceleration of 0.60 rad/s. (The formula for the moment of rotational inertia for the cylinder in this situation is I-% mr, where "m" is the mass and "t" is the...
