Determine the acceleration a x of collar B as a function of y if collar A is given a constant upward velocity v A Note that y and L form the sides of an equilateral triangle. Label the third side and write the relationship between the length of the three sides. Can you Determine the acceleration relationship? IC13.2 Dual Collar Slide What is your first step? Solution: Problem Type: Find: Given: v A = Constant up a x Constrained Motion Reflection: Constrained motion problems can be solved by differentiation of geometric identities Differentiate the equation again x 2 2 2 y x L + = y y x x 2 2 0 +
