Where is neutral axis of the gutter section with reference from the bottom of the channel? What is the moment of inertia of the section with respect to the X-axis? What is the reaction of the hinge support at B? What is the maximum flexural stress of the beam? What is the flexural stress 3 ft. from the roller support at D ?

Problem # 3: A gutter beam is composed a C 6x13 channel and 2 pcs. of % "x7
steel plate whose section is shown below. The beam is overhang in the left side 3
ft. from support B. and carry a uniformly distributed load w=25 lbs/ft. including
its own weight and two concentrated load P1= 5 lbs. and P2= 10 lbs located as
shown.
