    The total recordable incident rate (TRIR) is a measure of occupational safety and health, useful for comparing working conditions in workplaces and industries.It is calculated by combining the actual number of safety incidents and total work hours of all employees with a standard employee group (100 employees working 40 hours a week for 50 weeks a year).

  6. Gauge factor - Wikipedia

    en.wikipedia.org/wiki/Gauge_factor

    Gauge factor (GF) or strain factor of a strain gauge is the ratio of relative change in electrical resistance R, to the mechanical strain ε. The gauge factor is defined as: [ 1 ] G F = Δ R / R Δ L / L = Δ R / R ε = 1 + 2 ν + Δ ρ / ρ ε {\displaystyle GF={\frac {\Delta R/R}{\Delta L/L}}={\frac {\Delta R/R}{\varepsilon }}=1+2\nu +{\frac ...

    The pocket-sized Hewlett-Packard HP-35 scientific calculator was the first handheld device of its type, but it cost US$395 in 1972. This was justifiable for some engineering professionals, but too expensive for most students. Around 1974, lower-cost handheld electronic scientific calculators started to make slide rules largely obsolete.
