F = (area of plate) du dy " where u(y) is the velocity profile and w corresponds to the fixed plate. The student concludes that for case I, as (du/dy)w is positive, the force acts to the right. The student now uses this formula to calculate the force on the stationary plate in case II and concludes that as (du/dy) is negative, the force on the upper plate in case II is to the left. Is the student's analysis correct? If not, clearly indicate what the error is. Clearly show how to correct the student's analysis, and compute the correct force on the upper plate in case II. Stationary II Stationary Case I Case II F = (area of plate) du dy " where u(y) is the velocity profile and w corresponds to the fixed plate.
