A uniformly dense rod with a length of 4 m and a mass of 6 kg is free to rotate around a frictionless axle through the center of the rod. Three forces are acting on the rod as shown in the figure below. 2 m 0.8 m 15 N 4 N 10 N 2 m 30° N What is the net torque (in Nm) acting on the rod? 0.665

The angular speed of a rotating platform changes from W equals 2.8 rads/S to W equals 6.8 rad/S at a constant rate as a platform moves through an angle 5.5 rad. The platform has a radius of R equals 28 cm  w0=2.8rad/s w=6.8rad/s 0=5.5 radians r=28cm   calculate the angular acceleration of the platform a in rad per second squared calculate the tangential acceleration, aT in meters per second squared of a point on the surface of the platform at the outer edge
