The weight w that a horizontal beam can support varies inversely as the length l of the beam. suppose that an 8 dash m beam can support 900 kg. how many kilograms can a 19 dash m beam support?

The number of kilograms a 19 m beam can support is:

                               378.9474 kg

It is given that:

The weight W that a horizontal beam can support varies inversely as the length L of the beam.

Let k denote the constant.

This means that the weight W and Length L is related as:

Suppose that an 8 dash m beam can support 900 kg.

This means that L=8 and W=900

Then,

Now , we are asked to find the value of W when L= 19

i.e.

x-3y=4
