Determine its angular acceleration
Webmass of 15 kg and its mass center is at point G. Find: The reactions at the pin O and the angular acceleration of the rod just after the cord is cut. Plan: Since the mass center, G, moves in a circle of radius 0.15 m, it’s acceleration has a normal component toward O and a tangential component acting downward and perpendicular to r G. WebA disk 8.00 cm in radius rotates at a constant rate of 1200 rev/min about its central axis. Determine (a) its angular speed in radians per second, (b) the tangential speed at a point 3.00 cm from its center, (c) the radial acceleration of a point on the rim, and (d) the total distance a point on the rim moves in 2.00 s.
