The cross-section of beam shown in the figure has the following
dimensions and characteristics :
c_{t} = 1.357 cm
c_{b} = 2.643 cm
= 9.44 cm^{4}
The distribution of the internal moment along the axis of the beam, M(x),
has been investigated for you. It was found that the internal moment M(x)
varies between -600 Nm and +900 Nm.
What is the maximum compressive flexural stress inside the beam ?
Does it occur at the bottom or top of the beam ?
What is the maximum tension inside the beam ?
Does it occur at the bottom or top of the beam ?
Note : In case you forgot our sign conventions : a positive moment
results in tension at the bottom and compression at the top of a beam.
