KINEMATICS PRACTICE

Below is a system that we looked at in Lecture 12.

Suggestion: Derive an expression for F^ a Q two ways: 1) Assume that point Q is fixed on rod C (i.e., assume L is constant). 2) Assume that point Q is sliding along rod C (i.e., assume the L changes as a function of time).

Do each derivation using as many different approaches as possible (e.g., rotation matrices and unit vector conversions, the Golden Rule, and two points fixed on a rigid body). By using multiple approaches, you will be forced to use EVERY important kinematics concept that we have covered in the course.

I do not have any solutions generated for this problem, but you can check your solutions by deriving your expressions for F^ a Q using different approaches (and also by comparing your results with those of other students in the class).
