QUESTION 3 The design calculations for a rod, which is subjected to static loading conditions and a given design factor, yield a diameter value of 0.74 cm. The manufacturing process is able to produce these rods in the following fractional diameters: 0.5 cm, 0.6 cm. 0.7 cm, 0.8 cm, 0.9 cm, and 1 cm. Which of the following values would represent an appropriate choice for the preferred fractional diameter for this rod? O a. 0.5 cm O b. 0.7 cm O c. 0.8 cm O d. 1 cm

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.
