The symmetrical beam shown is made of a material for which the allowable stress is 40 MPa in tension and 100 MPa in compression.
a- Locate its centroid.
b- Calculate the centroidal moment of inertia that will resist the bending moment.
c- Determine the maximum bending moment that can be applied on the beam.
d- Determine the corresponding radius of curvature. Use E = 200 GPa.
