Design a rod that will have an interference fit so that the allowance (the maximum interference) is 0.010 with the center hole in the Rocker Arm

and the tolerance on the rod diameter is .002. Sketch a section view of

your rod design. Be sure to specify the tolerance in the diameter

dimension of your design.

Apipe with an outside diameter of 15 cm is exposed to an ambient air and surrounding temperature of -20°c. the pipe has an outer surface temperature of 65°c and an emissivity of 0.85. if the rate of heat loss from the pipe surface is 0.95 kw per meter of length, the external convective heat transfer coefficient (h) is: (a) 12.5 w/m"k (b) 18.6 w/mk (c) 23.7 w/mk (d) 27.9 w/mk (e) 33.5 w/mk
