Free Body Diagram

The system of forces acting on a body tends to either rotate it or make the body undergo motion. In general, when an external agent exerts a force on a body, the body undergoes translational motion and rotational motion. The body has six degrees of freedom under the influence of that force. Here, three degrees of freedom are from the translational motion while the other three are from the rotation motion. However, sometimes the bodies are not allowed to undergo any motion and are fixed, under such conditions the body is said to be constrained.

EXAMPLE 3 Evaluate 2 dx V3 +4r2
Now consider the figure shown below. N CG -A tip In the above figure the block is just on the verge of tipping: W and N act through point A and thus exert zero torque about point A. The incline angle, Otip, is the incline angle beyond which the block will tip, since increasing the angle beyond Otip will move the CG beyond where there is a point of support below it, as in the previous figure. It is not difficult to show, using some geometry and trigonometry, that Otip is given by Orip = tan' (w / h) (1) Equation (1) agrees with our intuition: If the block is short and wide (h small, w large) the block will be more difficult to tip (Otip is large) and if the block is tall and narrow (h large, w small) the block will be easier to tip (0tip is small). It is now not difficult to see why the automotive industry defines a safety factor describing how easily a vehicle will rollover as (roughly) vehicle width / vehicle height. The larger this safety factor is, the more resistant the vehicle is…
