31. In the armature, an electromotive force is created by the relative motion of the armature and the field. 32. What is essential is relative motion . 33. Mechanism made of several bodies, the number of possible independent relative motions between the pieces of the mechanism. 34. Kinetic friction occurs when the two objects are undergoing relative motion and they are sliding against each other. 35. The drag caused by relative motion of the fluid and a surface is a measure of the viscosity. 36. The pitch maneuver to be added to compensate for the relative motion between the spacecraft and the planet. 37. The Chaves graben was formed by the relative motion of the block with different types of sediments being settled. 38. The mode shape vectors are not the absolute motion, but just describe relative motion of the degrees of freedom. 39. The abrasive and the material to be worked are brought into contact while in relative motion to each other. 40. When these bends or discontinuities are in the same direction as the relative motions along the fault, extension occurs.
