The shaft is supported at ils ends by two bearings a and band is subjected to the forces applied to lhe pulleys fixed to the shaft. determine the resultant internal loadings acting on the cross section at point c. the 400-n forces act in the - z dir ection and the 200-n and 80-n forces act in the y direction. the journal bearings at a and b exert only y and z components of force on the shaf1.

The “death throes” of stars are amongst the most complex phenomena in all of astronomy, and the “corpses” of stars amongst the most energetic and exotic objects in existence. beginning at the end of the core helium fusion stage in a star’s life, describe in detail the post-main sequence development of both (a) a 1.0 solar mass star, and (b) a 25.0 solar mass star. in what significant ways do they differ? what role does each of these types of stars play in the "star-gas-star" cycle and the evolution of chemical elements in our galaxy?
