The ears of a rabbit can be thought of as two rectangular fins that dissipate heat. The dimensions are 0.1 cm thickness, 3 cm width, and 7 cm length. The average body temperature of a rabbit is 38°C. Assume this to be the temperature of the base of the head where the ears are located. The top of the head can be assumed to be a surface with area 42 cm², neglecting the area (including the base) of the ears. Assume an adiabatic tip condition for the ears. Also, neglect radiation. The thermal conductivity of the rabbit's skin is 3 W/m.°C. The convection coefficient and temperature of the air are 8 W/m².°c and 10°C, respectively. With this in mind, find the total heat transfer from the top of the rabbit's head including the ears. 1315 W

The channel shape cross-section and the rectangular cross-section shown in the Figure Q4 are made of materials with elastic-perfectly plastic behaviour. The yield stress of the material used for the channel shape cross-section is σy = 449 MPa, whereas that used for the rectangular cross- section is 0.7%y. Compute the thickness of the web, t, of the channel shape section if the two cross sections have identical plastic bending moment about the z-axis. In Figure 4, h= 96 mm, b=43 mm, a=12 mm, H=96 mm, d= 43 mm N b h a Z a | d H
