Question

Consider the cross section of a beam shown below. Assume the beam is experiencing an internal shear force of 5,000 N. Using this information, calculate the magnitude of the bending shear stress at the horizontal centroidal axis of the cross section. Consider the cross section of a beam shown below. Assume the beam is experiencing an internal shear force of 25 kN. You may also take the upper horizontal centerline to be the location of the horizontal centroidal axis. Note that the lower horizontal centerline is marking the height of the center of the R37.5 are. Calculate the magnitude of the bending shear stress at an axis 45 mm above the bottom edge of the section.

Explanation / Answer

I will tell the Procedure to ans ( becuz i am nt able to slove now)

1. First find the Centriod (x,y) of the composite section by subtracting the circular part

2. Multpliy Ix = Axc2 for getting the Moment of Inertia

Shear bending Stress = VQ / IB

V = Shear Force ( Given)

Q = Length from the axis

I = Moment of Inertia

B = thickeness ( Given)
