A steel rod, which is free to move has a length of 200mm anddiameter of 20mm at a temperature of 15oC. If the rod isheated uniformly to 115oC, determine the length andthe diameter of this rod to the nearest micron at the newtemperature if the coeffiecient of thermal expansion of steel is12.5 x 10-6m/m/oC. Is there a stress on therod at 115oC.
Also if the rod is snugly fitted against two immovablenonconducting walls at a temperature of 15oC and thenheated uniformly to at 115oC, what is its length at115oC? If the modulus of elasticity of steel is 207 GPa,what is the stress induced in the bar? Is this stress tension or compression?
An earthen channel will be excavated into sandy soil for which Vmax = 4.0 ft/sec, n = 0.022, and the recommended m = 3. The channel will have a bottom slope of 0.0011 and accommodate a design flow of 303 cfs. Design (size) the channel section.
