Physical Development The two main areas of physical development are gross & fine motor skills. Gross motor skills use the larger muscles in the body like arms & legs. Rolling over‚ crawling‚ walking‚ running and jumping are all gross motor skills. Fine motor skills use the smaller muscles in the body‚ like fingers & toes. Writing‚ painting‚ pointing‚ grasping and reaching are examples of fine motor skills. Fine motor skills alsto eye coordination. Activities to promote Physical Development

Chapter (11) Synchronous Motors Introduction It may be recalled that a d.c. generator can be run as a d.c. motor. In like manner‚ an alternator may operate as a motor by connecting its armature winding to a 3-phase supply. It is then called a synchronous motor. As the name implies‚ a synchronous motor runs at synchronous speed (Ns = 120f/P) i.e.‚ in synchronism with the revolving field produced by the 3-phase supply. The speed of rotation is‚ therefore‚ tied to the frequency of the source. Since

INTRODUCTION GROWTH OF MOTOR INSURANCE Vehicle first appeared on the roads in United Kingdom (UK) during 1880’s‚ but the first motor insurance is issued during 1890’s. Therefore it is almost 10 years time people use a motor vehicle as a mode of transportation without insurance coverage. Therefore‚ through their (insurer) experiences on other classes of insurance such as fire‚ theft & liability‚ they introduce the motor insurance towards the use of transportation. Then they emphasis it (motor insurance) on

AC motors run at fixed speed set by the line frequency. Easy speed‚ torque & direction controls in DC motors. DC motors are generally operate at lower voltages which makes these easier to interface with control

ultrasonic motor INTRODUCTION All of us know that motor is a machine which produces or imparts motion‚ or in detail it is an arrangement of coils and magnets that converts electric energy into mechanical energy and ultrasonic motors are the next generation motors. In 1980‚the world’s first ultrasonic motor was invented which utilizes the piezoelectric effect in the ultrasonic frequency range to provide its motive force resulting in a motor with unusually good low speed‚ high torque

The Generals In my personal opinion‚ I think that the Generals assemblage was a great success. Many websites and a book that I have looked at said that the statue gives off a humorous feel than serious. Most serious sculptures would only depict one rider on a steed‚ whereas the Generals has two men (one being our country’s Founding Father and the other Simón Bolívar‚ the political and military leader of Venezuela). It is also to be noted that the way the horse is depicted in the statue--it is very

SISTEMAS DC Motors Catedrático: Ing. Gustavo Mendoza Leal Alumno: Alfredo Valdés Cárdenas Introduction A DC motor is a type of electrical machine that converts direct current into mechanical power by means of a magnetic field. DC motors are widely used in field applications because of their many advantages over AC motors such as speed control‚ high starting torque‚ quick starting‚ stopping‚ reverse and acceleration and free from harmonics found in AC. Applications of DC motors include but
