The bar is defined using the SI derived unit, pascal: 1 bar ≡ 100,000 Pa ≡ 100,000 N/m 2. Thus, 1 bar is equal to: 1,000,000 Ba (in cgs units); and 1 bar is approximately equal to: 0.98692327 atm; 14.503774 psi; 29.529983 inHg; 750.06158 mmHg; 750.06168 Torr
To calculate the force to shear a 25 mm diameter bar of EN8 bright steel; area of the bar in mm 2 = (12.5 2)(π) ≈ 490.8 mm 2 0.8 kN/mm 2 × 490.8 mm 2 = 392.64 kN ≈ 40 tonne-force 40 tonne-force × 0.6 (to change force from tensile to shear) = 24 tonne-force
The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m 2). [1] It is also equivalent to 10 barye (10 Ba) in the CGS system. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar , and the kilopascal (1 kPa = 1000 Pa), which is equal to ...
Glass chart. A 1951 USAF resolution test chart is a microscopic optical resolution test device originally defined by the U.S. Air Force MIL-STD-150A standard of 1951. The design provides numerous small target shapes exhibiting a stepped assortment of precise spatial frequency specimens.

The SI unit for pressure is the pascal (Pa), equal to one newton per square metre (N/m 2, or kg·m −1 ·s −2). This name for the unit was added in 1971; [7] before that, pressure in SI was expressed in newtons per square metre. Other units of pressure, such as pounds per square inch (lbf/in 2) and bar, are also in common use.
Crumble about 2/3 of the cookie dough into the pan and press into an even layer, like a crust. Use a tablespoon to dollop the jam on top, then spread it out evenly, leaving about 1/4 inch bare ...
US/Imperial bar sizes give the diameter in units of 1 ⁄ 8 inch (3.2 mm) for bar sizes #2 through #8, so that #8 = 8 ⁄ 8 inch = 1-inch (25 mm) diameter. There are no fractional bar sizes in this system. The "#" symbol indicates the number sign, and thus "#6" is read as "number six". The use of the "#" sign is customary for US sizes, but "No ...
