5.7 Drawing Free-Body Diagrams - General Physics Using Calculus I Draw a free-body diagram for each block. Solution Significance Each block accelerates (notice the labels shown for →a 1 a → 1 and →a 2 a → 2 ); however, assuming the string remains taut, they accelerate at the same rate. Thus, we have →a 1 = →a 2 a → 1 = a → 2. PDF Lecture 13 - rpi.edu : A an idealized model and free- body diagram of the foot pedal. EQUATIONS OF EQUILIBRIUM (Section 5.3) ∑F x = 0 ∑F y = 0 ∑M O = 0 where point O is any arbitrary point.
