NEED HELP PLEASE ASAP!

The three beams shown have approximately the same cross-sectional area. Beam 1 is a with flange plates (, , , , , , , ); Beam 2 consists of a web plate with four angles (, , , , , ); and Beam 3 is constructed of 2 C shapes with flange plates ( , , , , , , , ).

Assume allowable stress values are: and . The most economical beam is that having the largest capacity-to-weight ratio. Neglect fabrication costs in answering (c) and (d) below.

The three beams shown have approximately the same cross-sectional area. Beam 1 is a W 14 x 82 with flange plates (Ay = 24 in.?, hy = 14.3 in., Iw = 881 in.4, b, = 8 in.
t = 0.52 in., b = 10.1 in.,t = 0.855 in., t = 0.51 in.); Beam 2 consists of a web plate with four angles (A, = 5.77 in.?, ca = 1.67 in., ha = 6 in., I, = 19.9 in.4, b2 = 14 in.,
ti = 0.675 in.); and Beam 3 is constructed of 2 C shapes with flange plates ( Ac = 14.7 in.?, he = 15 in., I. = 404 in.“, bg =4 in., t3 = 0.375 in., b = 3.72 in., t = 0.65 in.,
t = 0.716 in.).
Assume allowable stress values are: o, = 18 ksi and Ta = 11 ksi. The most economical beam is that having the largest capacity-to-weight ratio. Neglect fabrication costs in answering (c) and (d)
