In linear algebra, two rectangular m-by-n matrices A and B are called equivalent if = for some invertible n-by-n matrix P and some invertible m-by-m matrix Q.Equivalent matrices represent the same linear transformation V → W under two different choices of a pair of bases of V and W, with P and Q being the change of basis matrices in V and W respectively.
In 1942, a variant of the StuG Ausf. F was designed with a 10.5 cm (4.1 in) true howitzer instead of the 7.5 cm StuK 40 L/43 cannon. These new vehicles, designated StuH 42 (Sturmhaubitze 42, Sd.Kfz 142/2), were designed to provide infantry support with the increased number of StuG III Ausf. F/8 and Ausf.

The ZiS-3 combined the light carriage from the 57 mm ZiS-2 anti-tank gun and the powerful 76.2 mm barrel from the F-22USV, the previous divisional field gun. The addition of a muzzle brake reduced recoil and prevented damage to the light carriage upon firing.
A kilogram-force per square centimetre (kgf/cm 2), often just kilogram per square centimetre (kg/cm 2), or kilopond per square centimetre (kp/cm 2) is a deprecated unit of pressure using metric units.
