Question
A lightweight lever consists of a 0.8m solid bar rigidly mounted to a large structure and a 0.5m solid lever
welded to the solid bar. Using the loading indicated and assuming the material has a Young's Modulus of
200 GPa and a shear modulus of 86 GPa, calculate:
(a) the maximum stress at Point A on the Cross-section a-a,
(b) the vertical displacement of the knob when the load is applied relative to Cross-section a-a.
