A rod segment is either stretched or squeezed by a pair of forces acting along its length and perpendicular to its cross-section. First, we’ll create a simple bar chart. The method is demonstrated in the following examples. A compound bar consists of two bars of equal length. There are two different ways to display the values of each bar in a bar chart in matplotlib –. a body immersed in a fluid experiences a vertical buoyant force equal to the weight of the fluid it displaces. First, we draw the axes, the pivot, and the three vectors representing the three identified forces. Moment of Inertia for Uniform Objects.
