The wooden beam is made out of four pieces using nailslongit

The wooden beam is made out of four pieces using nails(longitudinal surface at location\"M\") and adhesive (at the two longitudinal surfaces\"L\"), as shown in the figure. The distance between two nails is 80 mm along the beam. The beam is simply supported at A and C and subjected to two concentrated loads at 8 and D. Consider location C of the beam as the most critical one. Calculate the maximum tensile normal stress in the wood The minimum required shear strength of the selected adhesive The average transverse force supported by each nail

A horizontal piston-and-cylinder system is subjected to 1 bar external pressure. This piston and cylinder do not conduct heat, but heat can be added to the steam by a heating coil. The steam has an initial temperature of 300C and enough heat is added to increase the temperature by 200C.

a) Determine the amounts of heat and work for this process.

b) The thermometer that measures the temperature at which the heat is being transferred is broken. Using your thermodynamic knowledge, determine the minimum value for this temperature.
