An exerciser begins with his arm in the relaxed vertical position OA, at which the elastic band is unstretched. He then rotates his arm in the horizontal position OB. The elastic modulus of the band is k=60N/m-that is, 60 N of force is required to strentch the band one meter of elongation. Determine the moment about O of the force which the band exerts on the hand B. Solution: 140 m Fig. 5

Electrical Plans

An electrical plan is also known as an electrical drawing or a wiring diagram. It is a kind of visual representation which bears the blueprint symbols of all the electrical components in electrical house plans or various building construction projects. In other words, electrical plans describe electrical circuits and systems that build up the electrical house plans or building plans. An electrical engineer who works on various construction projects creates an electrical drawing. The engineer outlines the electric planning with different symbols and lines forming a detailed electrical circuit. These drawings are a means of representation for the clients, who will carry out the actual wiring process. In a nutshell, an electrical plan showcases the circuitry with the proper placement of electric components.
