Engineering Mechanics - Dynamics Chapter 15 Problem 15-93 Determine the angular momentum H P of each of the particles about point P . Given: θ 30 deg = φ 60 deg = a 8m = f 1.5 m = m A 6kg = b 12 m = g 6m = v A 4 m s = c 2m = h = m B 4kg = v B 6 m s = d 5m = l 5 = m C 2kg = v C 2.6 m s = e = n 12 = Solution: H AP m A v A sin () ad m A v A cos bc = H AP 57.6 kg m 2 s = H BP m B v B cos cf m B v B sin de + + = H BP 94.4 kg m 2 s = H CP m C n l 2 n 2 + v C ch + m C l l 2 n 2 + v C dg + = H CP 41.2 kg m
