Question

A cantilever beam, which is made of an alloy with Young’s modulus of elasticity E=72×(10)9N/m2, is loaded transversely at its free end. If the length of the beam is 750 mm and the beam has an annular cross-section with inner and outer diameters of 110 mm and 120 mm, respectively, then determine the equivalent stiffness (in N/m) of this beam.
