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 5.3-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 45.2 kg, and each leg has a mass of 4.2 kg. 5.3 kg 0.6 m 0.5 m 0.8 m 1.6 m
