Design a frame to support a cast iron lathe. The lathe is 4 ft long, weighs 200 lbs, and is 8 inches deep. Compare three different beam designs to support this lathe and evaluate which one is the best to support transverse shear loading (you should ignore all other stresses for this portion). At least one of your beam designs should be "built up" (two or more sections joined together). • For one of your three beams, find the maximum shear stress at the interface between two sections (this applies to a built-up beam). • Occasionally, the lathe frame will need to be moved around. Assume that during this condition, a normal force of 200 lb. is added to your frame. Find the total state of stress from all sources of stress at the point of maximum shear stress you found above. 1. Draw Mohr’s circle for the state of stress. 2. Using your circle, estimate the principal stresses and maximum shear stress at this point.

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

The flow rate of air through a through a pipe is 0.02 m5/s. a pitot static tube is placed in the flow. the radius of the pitot static tube is 1 mm. assuming the flow to be steady and the air to be at 300k, calculate the difference in total and static pressure if the diameter of the pipe is: (a) d 0.1 m d 0.05 m (c) d 0.01 m
