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. Webangular acceleration is positive identify the units of angular acceleration degrees per second squared, radians per second squared, revolutions per second squared the procedure for identifying the direction of an angular motion vector is known as the right hand rule which of the following can be calculated as an instantaneous or average value
