What answer is considered the correct answer?gv3 said:
Not sure. I've still been unable to get the answer. I don't see any other way to approach this. My professor approached it the same way when he did a similar problem.Chestermiller said:
The next question asked for the max stress/average stress and used 30ksi as he average stress which gave me the right answer. I am hesitant to try because i only have 2 attempts left.Nidum said:
Axial force P is a type of mechanical force that acts parallel to the longitudinal axis of a structure. In the context of stress concentration, it refers to the force applied to a specific point on a structure, causing stress to accumulate and concentrate at that point.
The axial force P can be calculated using the formula P = F/A, where F is the applied force and A is the cross-sectional area of the structure. It is important to note that this calculation assumes a uniform distribution of stress over the entire cross-section of the structure.
Stress concentration occurs when the stress in a structure is not evenly distributed, resulting in a localized region of increased stress. This is often caused by the presence of sharp corners, holes, or changes in cross-sectional area. Axial force P can contribute to stress concentration by applying a force to a specific point on the structure, causing stress to accumulate and concentrate at that point.
There are several ways to reduce stress concentration caused by axial force P. One method is to use fillets or rounded corners instead of sharp corners in the design of the structure. Another approach is to use materials with higher strength and ductility, which can help distribute the stress more evenly. Additionally, increasing the cross-sectional area of the structure can also help reduce stress concentration.
Stress concentration analysis for axial force P is commonly used in the design and analysis of mechanical and structural components, such as beams, columns, and shafts. It is also important in industries such as aerospace, automotive, and civil engineering, where structural integrity and safety are crucial.
