Question )

F=22 kN single load, M=23 kN.m moment and w=17 kN/m distributed load are acting on the beam whose loading condition is given in the figure . The length L is also given as L=3 m . The cross-sectional properties of the beam are; body height y _g =223 mm , body thickness x _g =11 mm , flange width x _f = 170 mm , flange height y _f =18 mm . Point E on the section is located just below the flange-body junction. It is desired to determine the stress state in the section taken from the C level of the beam. According to this;

Question1-A ) Find the normal force (N _C) at point _C.( Write your result in kN .)

Question1-B ) Find the shear force (V _C) at point _C.( Write your result in kN .)

Question1-C ) Find the bending moment ( MC) at point _C.( Write your result in kN.m. )

Question 1-D) Find the moment of inertia of the beam section. ( Do your operations by converting the lengths to meters . Take at least 4 digits for the decimal part of your result and use the expression E for the decimal part. Instead of 0.005 , write it as 5E-3 .)

Question 1-E) For a section taken from the C point of the beam; Find the normal stress at point E on the beam section due to the bending moment . ( Write your result in MPa .)

Question 1-F) For a section taken from the C point of the beam; Find the shear stress at point E on the beam section due to the shear force . ( Write your result in MPa .)

Question 1-H) For a section taken from the C point of the beam; Find the normal stress that occurs at point E on the beam section due to the normal force . ( Write your result in MPa .)
