Consider the following uniformly loaded beam where w 50 lbi

Consider the following uniformly loaded beam, where w = 50 lb/in (external loading) and l = 120 inches:

Determine the peak bending stresses that result in the following I-beams

(Note that you must add the beam’s weight in lb/in to the external loading):

a) W6x20 (20 lb/ft)

b) W6x16 (16 lb/ft)

c) What is the physical reason for the difference in these peak stress values? (be specific) Hint: what is different about these beams?

Consider the following uniformly loaded beam, where w = 50 Vin (external loading) and t= 120 inches: Determine the peak bending stresses that result in the following I-beams (Note that you must add the beam\'s weight In (p/in to the extremely loading) W6x20 (20 (41ü) W8x16 What is the physical reason for the difference in these peak stress values? (be specification) different about these beams?

Solution

The peak bending stress in the given beam is 54mpa .

The main reason is the shape of the beam which Is going to distribute the wieght in different ways.
