Truss moment of inertia
WebL = mr 2 ω. But mr 2 term is thebody’s moment of inertia (I). L = I ω. We have learned that the torque induced on the body is the rate of angular momentum change . τ = dL/dt. Substituting angular momentum formula , τ = dIω/dt. τ = Idω/dt. The term dω/dt is the angular acceleration α of the body. i.e., α= dω/dt. WebA: B = L = 1.5 m Q=100 KN w= 35 % Gs= 2.7 and LL= 38.
