    "abstract": "The relativistic motion of an arbitrary point of an accelerated rigid rod is\ndiscussed for the case when velocity and acceleration are directed along the\nrod\u0027s length. The discussion includes the case of a time-dependent force\napplied to a single point, as well as a time-independent force arbitrary\ndistributed along the rod.\n  The time dependence of the rod\u0027s relativistic length depends on the\napplication point of the force, but after the termination of acceleration the\nfinal velocity and length do not depend on it. An observer on a uniformly\naccelerated rod feels an inertial force which decreases in the direction of\nacceleration. The influence of non-rigidity of realistic rods on our results is\nqualitatively discussed.",
