The design of the gear-and-shaft system shown requires that steel shafts of the
same diameter be used for both AB and CD. It is further required that the angle
D through which end D of shaft CD rotates not exceed 1.5°. Knowing that G =
77.2 GPa, determine the required diameter of the shafts.

Assume a Space Launch System (Figure 1(a)) that is approximated as a cantilever undamped single degree of freedom (SDOF) system with a mass at its free end (Figure 1(b)). The cantilever is assumed to be massless. Assume a wind load that is approximated with a concentrated harmonic forcing function p(t) = posin(ωt) acting on the mass. The known properties of the SDOF and the applied forcing function are given below. • Mass of SDOF: m =120 kip/g • Acceleration of gravity: g = 386 in/sec2 • Bending sectional stiffness of SDOF: EI = 1015 lbf×in2 • Height of SDOF: h = 2000 inches • Amplitude of forcing function: po = 6 kip • Forcing frequency: f = 8 Hz
13.44 The end of a cylindrical liquid cryogenic propellant
tank in free space is to be protected from external
(solar) radiation by placing a thin metallic shield in
front of the tank. Assume the view factor Fts between
the tank and the shield is unity; all surfaces are diffuse
and gray, and the surroundings are at 0 K.

The floor of the attic is characterized by a width of L₁ = 8 m while the roof makes an angle of 0 = 30° from the horizontal direction, as shown in the schematic. The homeowner wishes to reduce the heat load to the home by adhering bright aluminum foil (ε = 0.07) onto the surfaces of the attic space. Prior to installation of the foil, the surfaces are of emissivity & = 0.90. Attic A2, 82, T2 0 = 30° A1, E1, T₁ 土 L₁ = 8 m (a) Consider installation on the bottom of the attic roof only.
