We see that the plane on which the

**maximum**shear stress operates is still rotatedby the angle 45° from the initial, reference plane. However, the magnitude of this

shear stress is reduced — by an amount directly proportional to the magnitude ...

The

**maximum**tensile stress is found on the bar surface. The modulus of ruptureis equal to this stress at fracture and is obtained as <rr = 6M/bd2, where M is the

moment causing fracture, d the sample thickness, and b the dimension of the ...
