A beam of length L and mass M rests on two pivots. The first pivot is at the left end, taken as the origin, and the second pivot is at a distance { from the left end. A woman of mass m starts at the left end and walks toward the right end as in the figure below. L m M (a) When the beam is on the verge of tipping, find a symbolic expression for the normal force exerted by the second pivot in terms of M, m, and g. (Enter the magnitude.) n₂ = X = (b) When the beam is on the verge of tipping, find a symbolic expression for the woman's position in terms of M, m, L, and l. (c) Find the minimum value of that will allow the woman to reach the end of the beam without it tipping. (Use the following as necessary: m, M, and L.) {min =
