The spacing of joists in a floor system is 16-in. o. c. Floor dead load=15psf. Floor live load=185 psf. Deflection limits are L/360 for live load and L/240 for total load. Find: The required span rating, thickness, edge support requirements and panel orientation for the floor sheathing using ASD procedures.

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
