Select the correct answer from each drop-down menu. Discuss energy conversion in a steam engine. The steam engine is an external combustion engine that converts energy stored in fuels Into heat. The heat converts water into , which occupies greater volume than the same amount of water, thus creating pressure. This heat energy can be converted into energy.

Fluids at rest possess no flow energy. a)- true b)- false

Aturning operation is performed with following conditions: rake angle of 12°, a feed of 0.35 mm/rev, and a depth of cut of 1.1 mm. the work piece is aluminum alloy 6061 with t6 heat treatment (a16061-t6). the resultant chip thickness was measured to be 1.0 mm. estimate the cutting force, fc. use shear stress of 207 mpa and coefficient of friction on the tool face of 0.6.

The maximum shear stress and maximum flexural stress occur at the same location along a beam subjected to a non-uniform bending load. a)-trune b)- false
