a safety harness is connected to a cable with a report breaking stress of 800MNm2.
what mass could be hung from a harness if the diameter of the cable was 6mm.
how do I work this out?

  • Physics - ,

    800•10⁶ N/m² ….1 m²
    mg……………πD²/4= π(6•10⁻³)²/4
    mg=800•10⁶•π(6•10⁻³)²/4=22619 N
    m=22619/9.8=2308 kg
