Ability of an object o resist deformation As a measure of deflection for a positioning stage under load or of a leadscrew under thrust, stiffness is typically expressed in units of micro-inches per pound
The resistance to deformation of a structural member which can be measured by the ratio of the applied force to the corresponding displacement
excessive sternness; "severity of character"; "the harshness of his punishment was inhuman"; "the rigors of boot camp"
Stiffness is the resistance of a material or a structure to deformation It is not the same as strength The stiffness of a material is indicated by its "modulus of elasticity" - the measure of the elasticity of the atomic bonds within the material It is essential that calipers (and caliper mountings) be stiff Which is why metal matrix composite materials are used for racing calipers
The ratio of change in load to accompanying change in deformation of a member fabricated of a Hookean material and activated within its elastic limit; the slope of the load-versus-deformation plot beneath the elastic limit
Some systems of ODEs are difficult to solve using explicit methods The symptoms are that, in order to control the error, the step size must be kept smaller than the apparent rate of change of the variables If an adaptive step size is being used there may be more step rejections than expected
