e. Performasimplecalculationtodetermine theexpectedindicationonthetorquegauge basedontheknownhoistedweight.
Thisisacalculationthatmustbeperformedusingimperialunits(eg.,poundsandfeet).Thecalculationis:[KNOWNWEIGHT]
x[ARMLENGTH(infeet)].Forexample,ifthearmlengthis36inchesandthehoistedweightis1000lbsthecalculationis:
  1000x(36/12)=3000
 Therefore,theexpectedindicationonthetorquegaugeshouldbe3000lbs-ft.
