Chapter 15, Problem 108P

Each of the five connected particles has a mass of 0.9 kg, and G is the mass center of the system. At a certain instant the angular velocity of the body is w = 2.1 rad/s and the linear velocity of G is vg = 4.2 m/s in the direction shown. Determine the linear momentum of the body and it's angular momentum about G and about O. Assume a = 0.58 m, b = 0.29 m, c = 1.2 m, d = 0.9 m, 0 = 14° = 12° y d Answers: G Linear momentum: Angular momentum about G: Angular momentum about O: 6 b a UG G = i HG I I Ho I I (i -X i+ i+ i+ CA CO j+ i j+ M.

At a certain instant, the particle of mass m has the position and velocity shown in the figure, and it is acted upon by the force F. Determine its angular momentum about point O and the time rate of change of this angular momentum. Use m = 1.7 kg, a = 0.70 m, b = 1.19 m, c = 0.61 m, and F = 140 N and v= 1.5 m/s. +- Answers: Ho = i H₂ = (i a b с m i+ i+ MI F i --y j+ i j+ i k) kg m²/s k) Nom
