Wire rope is constructed of multiple strands of wire that are twisted and braided together to form a spiral design or helix. Once the separate wires are shaped into a solid form, they become a single wire with greater strength because the individual wires equalize pressure and have greater flexibility than the individual strands.

This chapter presents various types of pipe fittings. Of all the fittings, the elbow is the one most often used. Simply put, the elbow, or ell, is used when a pipe changes direction. Elbows can turn up, down, left, right, or any angle in between. When one finds it necessary to draw a 90° elbow or calculate how much space it will occupy in a…[더 보기]

Smart LED bulbs that can be controlled by a hub or smartphone app are no longer a new idea. What is new is how far this technology has come since its advent just a few years ago. Also new: Products like the Nanoleaf Light Panels—a system of interlocking LED panels that let you decorate with light—fundamentally change the light-bulb con…[더 보기]

DIY projects allow you to achieve the result that you desire. Utilizing your skills and artistic talents is related to this matter, and it’s also a way to save some bucks. With regards to this, many boaters can manage how to build a boat bench seat by themselves.

You may have wood for building boat seats. Some upgrades can be done by adding c…[더 보기]

A temperature sensor has been developed using an embedded system and a sensor head made of polymer-derived SiAlCN ceramics (PDCs). PDC is a promising material for measuring high temperature and the embedded system features low-power consumption, compact size, and wireless temperature monitor. The developed temperature sensor has been…[더 보기]

One of the most common uses of tarps and canvas is to protect furniture, carpets and other items while painting inside or outside. While canvas tarps are more expensive than disposable plastic tarps, they can be used over and over again. Canvas tarps are heavy and will stay in place without a lot of complicated taping and securing, and fit well…[더 보기]

The cheapest, crudest chargers use either a constant voltage or constant current and apply that to the batteries until you switch them off. Forget, and you'll overcharge the batteries; take the waterproof battery charger off too soon and you won't charge them enough, so they'll run flat more quickly. Better chargers use a much lower, gentler…[더 보기]

“It’s really taken off from no car monitor to tactile monitoring to taking a look at your eyes,” said Grant Courville, a vice president at BlackBerry QNX, which creates in-dash software systems. “I definitely see more of that coming as you get to Level 3 cars,” he added, referring to vehicles that can perform some self-driving functions in limite…[더 보기]

corrosion resistant control valve come in many forms: butterfly valve, ball and seat valve, disk-valve, piston-sleeve metering valve, and dart valve, to name but a few. Alumina has been used in many industrial valves. Water faucet valves of the standard disk-on-disk configuration are very common and are discussed in Section 12.2.8. Since they…[더 보기]

In this work, the shear rate is analyzed inside the drum of a concrete fuel tank truck. This is done to better understand the potential effect of transport, from the ready mix plant to the building site, in terms of the concrete final rheological state. From Section 1.2, a higher shear rate will imply increased dispersion of the cement particles…[더 보기]

A novel strategy for automatic control of the bus ac parts was developed based on numerous experimental test runs at various operating conditions, taking into account energy saving and thermal comfort without sacrificing the proper cycling rate of the system compressor. For this task, more than 50 test runs were conducted at different set point…[더 보기]

Injection molding is an established production process in which automotive mould manufacturers inject molten plastic materials into a mold cavity. The melted plastic then cools and hardens, and the manufacturers extract the finished part. Though the mold design process is critical and challenging (a poorly designed mold can result in defects),…[더 보기]

Roman earrings were similar to Etruscan styles until the first century C.E., when new styles with disks and pendants mounted on s-shaped ear hooks appeared. Colored stones and pearls were favored, and earring styles proliferated to satisfy the Roman taste for ostentatious display. At its height, the Roman Empire had the effect of standardizing…[더 보기]
