Answer:
weight is 442.10 kg
Step-by-step explanation:
given data
weight = 1400 kg
length = 6 m
to find out
how many kilogram 19 m beam support
solution
we know by inverse variation formula of weight that is
weight =
.............1
here k is constant and l is length
so k will be
1400 =

k = 8400
so for 19 m weight will be by equation 1
weight =
weight =
weight = 442.10 kg
