er from Part A, draw free-body diagrams or a load diagram and determine the internal axial forces in segments AB, BC, and CD. C)Using the internal axial forces determined in Part B, calculate the bar's maximum average normal stress. Using your free-body diagrams or load diagram from Part B and the axial stress equation, calculate the bar's maximum average normal stress.
A) The axially loaded bar is fixed at A and loaded as shown. Draw a free-body diagram and determine the support reaction at A. On paper, draw a free-body diagram of the bar and determine the reaction at A for the bar to be in equilibrium. Assume that the unknown reaction at A acts in the negative x direction.
B)Using the answer from Part A, draw free-body diagrams or a load diagram and determine the internal axial forces in segments AB, BC, and CD.
C)Using the internal axial forces determined in Part B, calculate the bar's maximum average normal stress. Using your free-body diagrams or load diagram from Part B and the axial stress equation, calculate the bar's maximum average normal stress.
