And acceleration. Pin accelerates to right for any angle 0θ′ cr,no mag- nitude of F′will move the pin. The intent of the question is to get the student to draw and understand the free body in order to recognize what it teaches. The graphic approach accomplishes this quickly.
It is important to point out that this understanding enables a mathematical model to be constructed, and that there are two of them. This is the simplest problem in mechanical engineering. Using it is a good way to begin a course.
What is the role of pin diameter d? Yes, changing the sense of Fchanges the response.
