200 mm 200 mm 200 mm Two L-shaped arms, each of mass 5 kg. are welded at the one-third points of the 600 mm shaft AB to form the assembly shown. Originally the assembly rotates at the constant rate of 360 rpm. Part of the solution on how to determine the kinetic energy of the assembly is shown below. You are to use the values below to determine the magnitude of the kinetic energy of the assembly in J, for a NEW 451 rpm Round your answer to the nearest whole number. Hint: Use the summation of the moments of inertia given at the bottom of the table. 200 m
SOLUTION m - 5 kg a = 200 mm = 0.2 m (2x)(360) = 12 rad's 60 - 7 = 12 rad 9 Use parallel axes x,y'.' with origin at the mass center as shown. 1 4102 $1,053 +54.0? - 10,0,1,0,0), - 1,0,0). 7 Segments 1, 2, 3, and 4, each of mass m' = 2.5 kg contribute to Part 1. + +1 12 4
