Asimply supported beam is to be 18’-0" long, braced only at its ends. select the lightest w-shape of a572 steel (fy = 50 ksi) given the conditions below. check the beam for shear and deflection. if the total load deflection (∆tl) is limited to l/300, would this beam still work? show work to explain your answer.

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: )
