Equation 1
weight of 2 bolt = 6.75 weight of washer
Equation 2
mass = W/g
Where
g = 9.8m/s^2
mass of box of 2 bolt = weight of 2 bolt x 2 bolt pcs/box/9.8 m/s^2
mass of box of 2 bolt = 6.75 weightwasher x 2 bolt pcs/box
if there are 144 pcs of bolts/box
mass of box of 2 bolt= 6.75 weight of washer x 144/9.8m/s^2
mass of box of 2 bolt = 972 weight of washer /9.8m/s^2
=99.18 weight of washer s^2/m
