  • The purpose of this lab is to explore the dynamics of the simple harmonic oscillator (SHO). To make things a bit more interesting, we will model and study the motion of an inverted pendulum (IP), which is a special type of tunable mechanical oscillator. As we will see below, the inverted pendulum contains two restoring forces, one positive and one negative.

  • Cloud drawing is a snap, and it's a great place to learn how to smudge your pencil lead when you are drawing. Don't miss the cloud drawing video at the end of the page. If the written guide is a little confusing the video guide at the bottom of the page should get you on the right track in no time. Step 1 - The cloud shape Create your shape using circular motions to define the outline.

  • When the filler is hard (usually 15 -20 mins) sand into shape using 40-60grit production paper. Power sanders can speed up this part of the job but care must be taken not to remove too much of the filler, particularly if using rotary sanding disks. Final shaping is best done with a flat sanding block with abrasive paper attached. Sand in straight lines, changing direction regularly to avoid sanding low spots or grooves into the filler. For the same reason never sand in a circular motion as this removes filler too quickly from the same spot. Once the filler...

  • The tactile examination of the breast is best performed with the patient re- cumbent with her arm raised above her head. A small pillow under her upper back can further distribute the breast tissue over the chest wall. Palpation is performed using the base of the fingertips in small circular motions with vari- able depth. Recall that breast tissue extends beyond the region usually defined by a bra cup.

  • Abstract This paper presents an implemented approach to part-mating of three-dimensional non-cylindrical parts with a 6 DOF manipulator, considering uncertainties in modeling, sensing and control. The core of the proposed solution is a reinforcement learning algorithm for selecting the actions that achieve the goal in the minimum number of steps. Position and force sensor values are encoded in the state of the system by means of a neural network. Experimental results are presented for the insertion of different parts – circular, quadrangular and triangular prisms – in three dimensions.

  • SUMMARY This chapter addresses the design of cam systems in which flexibility is not a consideration. Flexible, high-speed cam systems are too involved for handbook presentation. Therefore only two generic families of motion, trigonometric and polynomial, are discussed. This covers most of the practical problems. The rules concerning the reciprocating motion of a follower can be adapted to angular motion as well as to three-dimensional cams. Some material concerns circular-arc cams, which are still used in some fine mechanisms....

  • Since the time of Newton the basic structure of the solar system and the laws that govern the motions of the bodies within it have been well understood. One central body, the Sun, containing most of the mass of the system has a family of attendant planets in more-or-less circular orbits about it. In their turn some of the planets have accompanying satellites, including the Earth with its single satellite, the Moon. With improvements in telescope technology, and more recently through space research, knowledge of the solar system has grown apace.
