By our earlier argument, the tension, T , is parallel to the position vector r and therefore its moment about O is zero. On the other hand, the weight creates a moment about O which is M O = −lmg sin θk. orbay wilson

There are two main descriptions of motion: dynamics and kinematics. Dynamics is general, since the momenta, forces and energy of the particles are taken into account. In this instance, sometimes the term dynamics refers to the differential equations that the system satisfies (e.g., Newton's second law or Euler–Lagrange equations), and sometimes to the solutions to those equations. However, kinematics is simpler. It concerns only variables derived from the positions of objects … WebContinuity Equation RTT can be used to obtain an integral relationship expressing conservation of mass by defining the extensive property B = M such that β = 1.
