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.

Question

A simple curve has two tangents
intersecting at an angle 19 and a degree of
curve 0.52. For
safety purposes, the simple curve is to be
replaced by spiral curves on its outer
borders. If the
required length of throw is 2.2 and the
required central angle between SC and CS
is half the
central angle for the original simple curve,
determine the following:
1. The change in radius between the
original simple curve and the simple curve
that is
part of the spiral
2. Spiral angle at 1/3 the length from TS to
SC
