Velocity of an Object01:18

Velocity of an Object

213
Understanding how an object moves along a path requires distinguishing between motion over a time span and motion at a precise moment. A useful example is a vehicle traveling along a straight and level path, where its position at any given time is known. The initial step in analyzing this motion is to measure how far the vehicle travels over a fixed time period. This measurement, called average velocity, is computed by dividing the total change in position by the duration over which the change...

Sequence Networks of Rotating Machines

503
A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Machines

584
Machines are complex structures consisting of movable, pin-connected multi-force members that work together to transmit forces. One example of a machine is the cutting plier, which is used to cut wires by applying forces to its handles. When equal and opposite forces are exerted on the handles of the cutting plier, they cause the cutting edges to come together and apply equal and opposite reaction forces on the wire, which are greater than the applied forces.

A toggle clamp is a mechanical device commonly used for holding and clamping objects in various applications, such as woodworking, metalworking, and assembly operations. Consider a toggle clamp subjected to a force of 200 N at the handle. The vertical clamping force can be calculated, provided the dimensions of the toggle clamp are known.
The toggle clamp system is a machine structure consisting of movable, pin-connected multi-force members that form a stabilized system to transmit forces. The...

Area of Science:

  • Molecular engineering
  • Materials science
  • Nanotechnology

Background:

  • Future nanomachines require molecular-scale motors capable of performing work and inducing collective motion in larger objects.
  • Developing synthetic motors that can interact with and manipulate macroscopic structures is a key challenge in nanotechnology.

Purpose of the Study:

  • To design and demonstrate a synthetic, light-driven molecular motor capable of rotating objects significantly larger than itself.
  • To investigate the mechanism by which molecular motor activity translates into macroscopic object manipulation.

Main Methods:

  • Fabrication of a synthetic, light-driven molecular motor.
  • Embedding the molecular motor within a liquid-crystal film.
  • Observing the motor's effect on the liquid-crystal surface relief and the rotation of submillimetre-sized particles.

Main Results:

  • The molecular motor successfully rotated objects exceeding its own size by a factor of 10,000.
  • The motor's shape changes induced significant rotational reorganization of the liquid-crystal film and its surface relief.
  • This surface reorganization ultimately led to the rotation of submillimetre-sized particles placed on the film.

Conclusions:

  • A synthetic, light-driven molecular motor can effectively induce macroscopic motion.
  • The interaction between molecular motors and liquid crystal films offers a viable pathway for nanoscale to microscale actuation.
  • This work lays the foundation for developing advanced nanomachines capable of controlled manipulation of larger structures.
