Ultimate Load (P) 35,000 pounds Original Diameter 0.450 inch Original Gage Length (Lo) 2.00 inch Diameter After Test 0.350 inch Final Gage Length (Lf) 2.30 inch Area of a circle = π r2 (π = 3.14) = Ao Radius = ½ Diameter (Ultimate Tensile Stress) UTS = P/Ao %E = ((Lf – Lo) / Lo) * 100% Given the listed values, list below A. The Ultimate Tensile Strength and B. The % Elongtation

Consider a double atwood machine constructed as follows: a mass 4m is suspended from a string that passes over a massless pulley on frictionless bearings. the other end of this string supports a second similar pulley, over which passes a second string supporting a mass of 3m at one end and m at the other. using two suitable generalized coordinates, set up the lagrangian and use the lagrange equations to find the acceleration of the mass 4m when the system is released. explain why the top pulley rotates even though it carries equal weights on each side.
