Webb4 mars 2024 · If the rod is pinned at both ends, the pin joints can transmit forces, but not bending moments. If you consider the equilibrium of the rod by taking moments about one end, the line of action of the force at the other end must be along the rod, otherwise there would be a non-zero moment acting on the rod and it would rotate. Webb22 aug. 2024 · 3. Suppose a rod is rotating in a horizontal frictionless plane, hinged at one of its ends. If the body is non rigid, it would change its length, but I am not sure whether it would elongate or get compressed. According to me, it should get compressed, as centripetal force acts towards the centre leading to compression of the rod.

Webb23 jan. 2024 · Using the horizontal component of net force: F y = T cos ( 20) − R H = 0. T cos ( 20) = R H. T = R H cos ( 20) Finding the moment around the hinge A: τ = T sin ( 20) ∗ 2 a sin ( 50) − m g ∗ a sin ( 50) = 0. T sin ( 20) = m g 2. T = m g 2 sin ( 20) Then, equating the two equations for T sin ( 20) I get: Webb24 feb. 2024 · Abstract. The impact of a ball with a rigid rod is a standard textbook problem with several surprises. We consider a hinged rod, as well as a free rod. Intuition … WebbCalculation: We have already learned from our Moment of inertia derivation for Rod, Moment of Inertia, I = 1/12 ML 2. Now, apply parallel axis theorem, the moment of inertia of the rod about a parallel axis which passes through one end of the rod can be written as, I’ = I + M (L/2) 2. I’ = 1/12 ML 2 + M (L/2) 2. mistoffelees lyrics
