Repeat Prob. 384 for a brittle material, requiring the inclusion of stress concentration in the fillet radius.
Question:
Repeat Prob. 3€“84, The cantilevered bar in the figure is made from a ductile material and is statically loaded with Fy = 250 lbf and Fx = Fz = 0. Analyze the stress situation in the small diameter at the shoulder at A by obtaining the following information.

(a) Determine the precise location of the critical stress element at the cross section at A.
(b) Sketch the critical stress element and determine magnitudes and directions for all stresses acting on it. (Transverse shear may be neglected if you can justify this decision.)
(c) For the critical stress element, determine the principal stresses and the maximum shearstress.

What I have learnt in my 8 years experience of tutoring is that you really need to have a friendly relationship with your students so they can come to you with their queries without any hesitation. I am quite hardworking and I have strong work ethics. Since I had never been one of those who always top in the class and always get A* no matter what, I can understand the fear of failure and can relate with my students at so many levels. I had always been one of those who had to work really hard to get decent grades. I am forever grateful to some of the amazing teachers that I have had who made learning one, and owing to whom I was able to get some extraordinary grades and get into one of the most prestigious universities of the country. Inspired by those same teachers, I am to be like one of them - who never gives up on her students and always believe in them!
