9. A meter stick is supported by a knife edge at the 50-cm mark. Doug hangs masses of 0.40 and 0.60 kg from the 20-cm and 80-cm marks, respectively. Where should Doug hang a third mass of 0.30 kg to balance the stick? (state the position on the stick) Draw the Free-Body Diagram. 10. A uniform bridge span weighs 50.0 × 10 N and is 40.0 m long. An automobile weighing 15.0 × 10, N is parked with its center...

Determine the reaction forces at A and B 50 N 50 N 2n 80 N 160 N 240 N 15 N 30 N 60 N We have studied static equilibrium of forces acting at a common point, and static equilibrium of forces not acting at a common point but involving moments. Now, we will study static equilibrium of entire objects, with the underlying assumption that the objects cannot move nor change shape. These objects are called rigid bodies. We will...
