String girdling Earth. String girdling Earth is a mathematical puzzle with a counterintuitive solution. In a version of this puzzle, string is tightly wrapped around the equator of a perfectly spherical Earth. If the string should be raised 1 metre (3 ft 3 in) off the ground, all the way along the equator, how much longer would the string be?
BMP-1-30 – Modernization of the BMP-1, a prototype was built and tested in 1997. It came with a standard BMP-1 chassis equipped with the BMD-2 turret with 30 mm 2A42 autocannon and UTD-230 diesel engine developing 360 hp (268 kW) (its maximum road speed was increased to 70 km/h). It carries 300 rounds for the main gun.
Machinist square. A machinist square or engineer's square is the metalworkers' equivalent of a try square. It consists of a steel blade inserted and either welded or pinned into a heavier body at an angle of 90°. Usually a small notch is present at the inside corner of the square. This prevents small particles from accumulating at the juncture ...

The type of wood or synthetic layers used to make up the blade will determine the blade's speed. The different types of rubber sheets affect the level of spin, speed, and other specific playing characteristics. Racket construction and new rubber technology contribute significantly to the amount of deviation from the expected ball flight path. [3]
The blade is made of non-rustproof carbon steel, blue-plastered by hand and finely forged from the base to the tip of the knife. The 90 mm (3.5 in) long blade shows patina (dark spots) caused by decades of use. It can easily be sharpened to a shaving sharp edge. Carbon steel is a popular choice for rough-use knives and cheaper options.
