4. Shown below is a steel tube AB with a 1.5" outside diameter and .06" wall thickness. You may assume that bar CBD is rigid. If F=50#, answer the following questions: a. Determine the state of stress at point A on the outside surface of the tube b. Draw Mohr's circle for the state of stress at A c. Find the principal stresses and directions at point A d. Determine the safety factor for the tube at point A based on the Maximum Shear Stress and Distortion Energy (Von Mises) failure theories and a proportional limit of 50ksi.

Die Stock

Die stock is expressed as the type of component which is utilized for fitting purposes while creating or shaping uniform threads on tubes, pipes, or screws. The die stock (die handle) has three screws around the adjustable part of a particular machine that helps to locate the die. Also, die stock can endure on a variety of hex and split adjustable dies of several dimensions. One of the primary reasons for using die stock in industries is because die stock can be operated by hands. Commonly, it is made up of high carbon steel.
