2020 F = ma Exam A — Question 21

A circular table has radius R and N > 2 equally spaced legs of length h attached to its perimeter. Suppose the table has a uniform mass density with total mass m, and neglect the mass of the legs. Assuming the table does not slip, the minimum horizontal force needed to tip over the table is  mgR h   mgR N −2 (B) sin π h 2N π mgR (C) cos h N  mgR N −2 (D) tan π h 2N  π  mgR sin (E) h 2N
