In order to make an adjustment, a group of engineering students remove leg D from a laboratory worktable. To ensure that the table remains stable, they place a 4.6-kg stack of statics textbooks centered at point E of the tabletop as shown. Determine the normal reaction force at each leg A, B, and C. The uniform tabletop has a mass of 39.5 kg, and each leg has a mass of 5.8 kg.
