an inner radius of \( 11 \mathrm{~cm} \) and an outer radius of \( 29 \mathrm{~cm} \). Three forces (acting perpendicular to the axis of rotation) of magnitudes \( 11 \mathrm{~N} \), \( 23 \mathrm{~N} \), and \( 16 \mathrm{~N} \) act on the object, as shown. The force of magnitude \( 23 \mathrm{~N} \) acts \( 30^{\circ} \) below the horizontal. Find the magnitude of the net torque on the wheel about the axle through the center of the object. Answer in units of \( \mathrm{N} \cdot \mathrm{m} \).

Wheel on a Frictionless Axis A wheel of radius $0.20 \mathrm{~m}$ is mounted on a frictionless horizontal axis. The rotational inertia of the wheel about the axis is $0.050 \mathrm{~kg} \cdot \mathrm{m}^{2} .$ A massless cord wrapped around the wheel is attached to a $2.0 \mathrm{~kg}$ block that slides on a horizontal frictionless surface. If a horizontal force of magnitude $P=$ $3.0 \mathrm{~N}$ is applied to the block as shown in Fig. $11-35$, what is the magnitude of the rotational acceleration of the wheel? Assume that the string does not slip on the wheel.
(II) The origin of a coordinate system is at the center of a whecl which rotates in the $x y$ plane about its axle which is the $z$ axis. A force $F=215 \mathrm{N}$ acts in the $x y$ plane, at a $+33.0^{\circ}$ angle to the $x$ axis at the point $x=28.0 \mathrm{cm}, y=33.5 \mathrm{cm}$ . Determine the magnitude and direction of the torque produced by this force about the axis.
A grinding wheel of radius $0.350 \mathrm{~m}$ rotating on a frictionless axle is brought to rest by applying a constant friction force tangential to its rim. The constant torque produced by this force is $76.0 \mathrm{~N} \cdot \mathrm{m}$. Find the magnitude of the friction force.
