Unformatted text preview: l credit: 5 points • 3 points if streamlines correct but did not determine acceleration field • 2 points if streamlines incorrect but correct acceleration field • 2 points if streamlines equation correct, but not plot/plotted incorrectly • 1 point if definition of acceleration field is correct NOTE: can add last two to first two (ie. If streamlines correct and definition of acceleration field correct, but acceleration field answer is wrong, = 3 + 1 = 4 points) Long answers: (total points = 60) #1: Full credit: 10 points Common errors: • 7 points if correct force, wrong line of action • 5 points if omitted force from Glycerin • 9 points if incorrect math, but correct equation setup • 9 points if forget to put in correct density for Glycerin (everything else correct) Additive points: • 1 point for writing down hydrostatic equation • 2 point for getting correct y’ for water side • 2 point for getting correct y’ for glycerin side • 1 point for summing the forces together • 1 point for doing all the math, integrals, etc.. correction • 1 point for writing down moment equation • 1 point for getting correct moments and place moments act • 1 point for getting moment math correct #2: Full credit: 10 points Common errors: • 9 points if equations and method is correct,...
