Consider a long fiber composite with Ef = 300 GPa, Em = 70GPa, and Vf = 0.4. When the composite is loaded to 1000 MPa, a fiber is found to fail. Using the shear lag model with constant friction stresst= 30 MPa, estimate the shear lag distance immediately following the break. The fiber diameter is 15 micrometers, and the frictional shear strength of the interface ist= 20 MPa
