Calculate the allowable uniform distributed load w for the composite beam shown below, if the stresses are limited to 120 MPa in the steel and 7 MPa in the timber. Take the transformation factor n=20.

x+2 because it just doubles hon so the pattern can actually tell you the expression.

so for example,

if x=2 then 2+2 is 4

if x=4 then 4+4 is 8

and so on and so forth.

i really hope that this makes sense and you out in a way hon: )
