[8] [19] Tom Lincir, founder of the Ivanko Barbell Company, has encountered 45-pound (20.4 kg) plates weighing as little as 38 pounds (17.2 kg), or as much as 59 pounds (26.8 kg). [20] Plates can be weighed, and the equipment marked (using a paint pen or other permanent marker) with the true weight. [21]
A complete suit of plate armour made from well-tempered steel would weigh around 15–25 kg (33–55 lb). [19] The wearer remained highly agile and could jump, run and otherwise move freely as the weight of the armour was spread evenly throughout the body. The armour was articulated and covered a man's entire body completely from neck to toe.
A call for a next generation plate, to stop even greater velocity threats than the ESAPI plate was issued by the U.S. Army in 2008. [5] The X Threat Small Arms Protective Insert plates are specifically allowed scalar or flexible systems, and asked for better coverage, with less than a pound of additional weight.
The larger the gauge number, the thinner the metal. Commonly used steel sheet metal ranges from 30 gauge to about 7 gauge. Gauge differs between ferrous metals and nonferrous metals such as aluminum or copper. Copper thickness, for example, is measured in ounces, representing the weight of copper contained in an area of one square foot.
Gusset plates are used to connect beams and columns together or to connect truss members. They can be either the only way of connecting the beam and columns or they can be used with bolts and welds. Gusset plates are therefore used in most metal weight-bearing structures, but the material and size of the gusset plate varies based on the structure.
A36 steel has a Poisson's ratio of 0.26 and a shear modulus of 11,500 ksi (79.3 GPa). [ 7 ] A36 steel in plates, bars, and shapes with a thickness of less than 8 inches (203 millimeters) has a minimum yield strength of 36 ksi (250 MPa ) and ultimate tensile strength of 58–80 ksi (400–550 MPa).

Thus 50 kg (~491 N) of plates will apply to the user only an equaling weight of 18 kg or a force of ~174 N at the beginning of the motion. On the other end of the spectrum may be a bent-over-row machine that is designed with the user's grip between the plates and the fulcrum.
