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 4.0-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 40.8 kg, and each leg has a mass of 5.3 kg. 0.5 m 1.1 m Answers: NA = NB = Mi Nc= i 4.0 kg B E 0.8 m 2.3 m N N N
