Problem 4 A uniform beam of mass M and length L is supported at its midpoint as shown. If an object of mass 4M is placed to the right of the midpoint at a distance from the midpoint of L/4, as shown, determine (a) The distance from the midpoint that an object of mass 2M needs to be for static equilibrium (b) Whether the object of mass 2M is to the right or to the left of the midpoint 4M
