Frame, Beam, types of loading and supports, Shear Force and Bending Moment diagram, relation among load-shear force-bending moment. FREE-BODY DIAGRAMS (Section 5.2) 1. Draw an outlined shape. Imagine the body to be isolated or cut "free" from its constraints and draw its outlined shape. 2. Show all the external forces and couple moments. These typically include: a) applied loads, b) the weight of the body, and c) support reactions (can be difficult). nent of velocity and that The free-body diagram is shown in Fig. T1.1b. Newton's second law gives and the components of acceleration including the effects of both gravity and air drag are (T1.2) The constant D depends on the density of air, the silhouette area A of the body (its area as seen from the front), and a dimensionless c...
