Bolts are manufactured by forging from round bar sections, usually with a hexagon shaped head. The steel material for bolts has a higher strength than ordinary structural steel, usually with an ultimate tensile strength of 800 or 1000 N/mm² and the material for nuts has a similar or higher strength.
Tensile Strength The tensile force required to produce a rupture in a strip of paper or paperboard, measured in MD & CD, expressed in kN/m. Tensile strength is indicative of fiber strength, fiber bonding and fiber length. Tensile strength can be used as a potential indicator of resistance to web breaking during printing or converting.

Nov 19, 2014· Tensile strength of paper is expressed in N/m (Force per unit length) everywhere. I am looking for a way to convert the tensile strength of paper to N/m^2 (Force per unit area). I assume this is because the paper strength might not be proportional to its cross sectional area. It should calculated separately for each paper weight
