A "biconvex" lens is one in which both surfaces of the lens bulge outwards. Suppose you had a biconvex lens with radii of curvature with magnitudes of |R1|=10cm and |R2|=15cm. The lens is made of glass with index of refraction nglass=1.5. We will employ the convention that R1 refers to the radius of curvature of the surface through which light will enter the lens, and R2 refers to the radius of curvature of the surface from which light will exit...

Single Cell Torsion (and a little buckling) 2. (20 pts) Suppose we wish to design a minimum weight shaft of Im length to support a limit Torque of 35 kN-m. The material is specified as aluminum 6061-T6 with yield strength of 240 MPa, Young's Modulus 70.0 GPa and Poisson Ratio 0.33. We recognize that for this pure torsion application a thin-walled, hollow circular shaft is the optimum configuration, but what radius and wall thickness will minimize the weight? Determine the...
