What is the slower speed of the ZX 1000 electric drill?
The ZX 1000 electric drill has two speeds: the fast speed is 3,000 rpm and the slower speed is 1,000 rpm. Adjust the speed according to the type of material and the size of the hole. For example, use the faster speed for a soft material such as wood to drill holes smaller than 10 millimetres (10 mm) in diameter but choose the slower speed for holes between 10 and 25 mm. However, for steel, a hard material, use the faster speed for holes smaller than 6.5 mm and choose the slower speed to drill holes between 6.5 and 10 mm.

The British are without doubt the most thoroughly watched people in the world. Although there are video cameras on nearly every street corner, the public seem unaware of their existence. Video cameras record drives who do not stop for a red traffic light, collisions between vehicles, reckless driving and violations of the speed limit on motorways. One explanation as to why these cameras are not considered an invasion of privacy is that both men and women feel safer knowing cameras can provide a form of protection. Citizens know that help is always available because guards are constantly watching the cameras. Cameras have also contributed to the combating of hooliganism at football matches and sports events, as the fans know they are under surveillance and their behaviour is much better than it used to be. Video cameras and security systems can keep the rise in the crime rate under control.

Plastic Materials
1. Plastic materials are not found in nature. Plastic is formed by extrusion or injection molding under very high pressure. It can be molded into any desired shape. Organic plastics are divided into two general groups: thermosetting and thermoplastic. The thermosetting group becomes rigid through a chemical change that occurs when heat is applied. These plastics cannot be remolded. The thermoplastic group remains soft at high temperatures and must be cooled before becoming rigid. This group is not used generally as a structural material.
2. Plastics are rapidly becoming important construction materials because of their great variety, strength, durability and lightness. Plastics are light. The benefits of light weight coupled with good strength and absence of corrosion offer tremendous potential as alternatives to traditional building materials. A given volume of polythene weights less than one-eighth of an equal volume of iron and less than half of the same volume of aluminum.
3. Plastics are used in the industry and in the household: from rockets and electronics to toys and house ware. Plastic products offer many advantages over the materials they replace, such as ease of handling, lower maintenance costs and rapidity of assembly. The insulation and dielectric properties of plastics led to their early use in the electrical engineering industry, which was followed by special application in mechanical engineering.
4. Using of plastics as materials for a construction in the form of sheets, rods or tubes is substituting the conventional metals. Plastics offer a lot of properties for the designs. Plastics have now been developed to such an extent that they can be applied to almost every branch of building, from the laying of foundations to the final coat of paint.
