Academics

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 6.4-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 39.2 kg, and each leg has a mass of 4.5 kg.
