WebMar 30, 2024 · Explanation: Specific Stiffness: It is the ratio of Young's Modulus of a material to its density, K s = E ρ. Its unit is J/kg With advanced technology, composite materials are being used in several places to reduce weight. Specific stiffness finds a major role to play in such industries. The specific strength is a material's (or muscle's) strength (force per unit area at failure) divided by its density. It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa⋅m /kg, or N⋅m/kg, which is dimensionally equivalent to m /s , though the latter form is rarely used. Specific strength has the same units as specific energy, and is relat… data analysis methods in research pdf
