Basic Mechanics

In our class, the goal is a mechanical goal (placing blocks into a bin) and electronics are used to control the mechanics. While it is not necessary to sit down and draw free body diagrams or figure out the static coefficient of friction between the LEGO tires and the game board, it is helpful to keep certain mechanical concepts in mind when ...

Body Levers – Body Physics: Motion to Metabolism

Mechanical Advantage. The ratio of load to effort is known as the mechanical advantage (MA). For example if you used a second class lever (like a wheelbarrow) to move 200 lbs of dirt by lifting with only 50 lbs of effort, the mechanical advantage would be four. The mechanical advantage is equal to the ratio of the effort arm to resistance arm. (2)

Work (physics) - Wikipedia

Work is the result of a force on a point that follows a curve X, with a velocity v, at each instant. The small amount of work δW that occurs over an instant of time dt is calculated as. δ W = F ⋅ d s = F ⋅ v d t {displaystyle delta W=mathbf {F} cdot dmathbf {s} =mathbf {F} cdot mathbf {v} dt}

Clarifier - Wikipedia

Clarifiers are settling tanks built with mechanical means for continuous removal of solids being deposited by sedimentation. A clarifier is generally used to remove solid particulates or suspended solids from liquid for clarification and/or thickening. Inside the clarifier solid contaminants will settle down to the bottom of the tank where it is collected by a scraper mechanism.

In the simplified construction of three-phase AC generator, the armature core has 6 slots, cut on its inner rim. Each slot is 60° away from one another. Six armature conductors are mounted in these slots. The conductors 1 and 4 are joined in series to form coil 1. The conductors 3 and 6 form coil 2 while the conductors 5 and 2 form coil 3.

Working Principle of DC Motor - StudyElectrical.Com

The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a mechanical force. The direction of the mechanical force is given by Fleming's Left-hand Rule and its magnitude is given by F = BIL Newton. The working of the AC motor ( Induction motor and Synchronous Motor ...

Different Types of Transducers | Characteristics ...

Output Transducers on the other hand, work in the opposite way i.e. their input signals are electrical and their output signals are non-electrical or physical like force, displacement, torque, pressure etc. Depending on the principle of operation, transducers can also be classified into mechanical, thermal, electrical, etc.

How does a hydraulic jack work: Pascals law - tec-science

Mechanical principle. In fact, this hydraulic amplification of the force is only one of a total of two principles applied to a jack. The much greater force amplification is due to the mechanical leverage. Usually it is a second class lever.

Mechanical aptitude describes the capacity to apply simple mechanical and physical principles. In other words, it describes a person's ability to figure out how objects work and move, alone and in relation to other objects. People often use mechanical aptitude to conquer routine problems. For example, mechanical

Work, Energy and Power - Georgia State University

Work-energy principle for angular quantities. The rate of doing work is equal to the rate of using energy since the force transfers one unit of energy when it does one unit of work. A horsepower is equal to 550 ft lb/s, and a kilowatt is 1000 watts. Index. Example.

Mechanical Centrifugal Air Classifiers - Chemical ...

CLASSIFIERS. Classification is a process of dividing a particle-laden gas stream into two, ideally at a particular particle size, known as the cut size. An important industrial application of classifiers is to reduce overgrinding in a mill by separating the grinding zone output into fine and coarse fractions.

Classification of Materials and Types of Classifiers ...

Industrial classification may be carried out in different types of classifiers and these classifiers are normally (i) hydraulic classifiers, (ii) mechanical classifiers, and (iii) cyclones. Basically they all work according to the principle that the particles are suspended in water which has a slight upward movement relative to the particles.

Basic Working Principle of Relay - Construction and Types

It consists of a flexible moving mechanical part which can be controlled electronically through an electromagnet, basically, a relay is just like a mechanical switch but you can control it with an electronic signal instead of manually turning it on or off. Again this working principle of relay fits only for the electromechanical relay.
