Front and rear light powered by a single dynamo. High intensity light for low light situations. Made in China. An effective product to use. Installed upside down fork and seatpost. The front and rear lights are powered by a single generator.. Headlight emitting a powerful light. Side lighting. Approved E6 reflectors. Does not require batteries. Fixes to a bike. No resistance - Always lit up, always safe - no maintenance required. If you are looking for a beacon that lights the road in places where public lighting is lacking, the RL700 is the most sensible choice. Its frictionless dynamo powers a headlight which emits a strong light and a wide beam on the road. The beacon emits light through a side of small holes, through an angle up to 270 degrees. The result is a greatly enhanced visibility in traffic. The front and rear lights are fitted with E6 approved reflectors. The front headlight is installed on the steering fork, above the front wheel, and the rear light is installed on the seat post. The front and rear RL700 lights are powered by a single generator mounted on the carrier. The magnets are placed on the rear wheel spokes. The light powers its own current with its eco-friendly coil and generator with magnets on the spokes of the wheel - no need for any battery. The light is attached to the bicycle: you never forget it. The light is always active and ensures greater safety in traffic, day and night. Through this magnet lamp, no more flat batteries, forgotten lights or resistance to pedalling. Nothing but a permanent lighting for constant security. The RL700 kit contains a headlight and tail light. Constant lighting: lights up when you ride and keeps going when you stop.

Resources, Tools and Basic Information for Engineering and Design of Technical Applications! This great website is a great lookup site for formulas and calculations used in the engineering world. Second Moment of Area or Area Moment of Inertia. Moment of Inertia of an Area, Area Moment of Inertia, also known as Second Moment of Area - I, is a property of shape that is used to predict deflection, bending and stress in beams.

Now consider the case of compressive loads and the instability they can cause. Consider only static instabilities (static loading as opposed to dynamic loading [e.g., flutter]) "A system becomes unstable when a negative stiffness overcomes the natural stiffness of the structure." Review some of the mathematical concepts. Limit initial discussions to columns.

Understanding of the stresses induced in beams by bending loads took many years to develop. Galileo worked on this problem,but the theory as we use it today is usually credited principally to the great mathematician Leonard Euler (1707{1783). As will be developed below, beams develop normal stresses in the lengthwise direction that vary from a maximum in tension at one surface, to zero at the beam's midplane, to a maximum in compression at the opposite surface. Shear stresses are also induced, although these are often negligible in comparision with the normal stresses when the length-to-height ratio of the beam is large.

This course covers the basic principles of elastic behavior for different materials such as wood, steel, concrete, and composite materials and compares the properties and applications of materials generally. It investigates cross sectional stress and strain behavior in flexure and in shear, and torsion as well as the stability of beams and columns. The qualitative behavior of combined stresses and fracture in materials is also covered.
