By the end of the vertical shaft with a horizontal axis with the load suspended from the rod of mass M = 10kg. It is suspended so that the point of suspension rods is on the axis of the shaft. Find strength tension rods if w1 = 2 rad / s. The length of the rod L = 1m. How to change the tensile force of the bar, if the angular velocity will increase to w2 = 4 rad. / Sec. Find time for two values of w1 and w2?
