A 1.8-m long rod that weighs 45N is placed on a circular horizontal board having a radius of 1.2m. The ends of the rod bear against the smooth circular rim around the edge of the table. The assembly is rotated at 100 rpm about the center of the table. Solve for the reactions on the rim at the ends of the rod. 1.8m r= 1.2m
