Question

a force p = 200 N is applied on a 25 mm thick bar with a 30 mm diameter hole on each end. a) what is the maximal average normal stress in the bar and where does it occur?

Example 5 - Typical link A force P = 200 N is applied on a 25-mm thick bar with a 30-mm diameter hole on each end. a) What is the maximal average normal stress in the bar and where does it occur? 20mm Answer: 0.53 MPa, where the hole is. (0.40 MPa in the middle of the bar)

Answer 1

P 200N 30mm 20 mm 45 mn 200NP Hackneno (t) = 25 mm two creatical Maximum strem com occurs at Sections A & B. * Stringate Bar - C415-30+ 25 = 200 -- = 0.533 Mmm? (45-30) * 25 Acla B, 200 70441mm? * Stress at P २०*25 oo = Process - (Ac)B from above Cancelation, we can seen, Се у до Hence, max = 0.533 10.533 Nim, at Ar Amy,
