Question

A prismatic bar PQRST is subjected to axial loads as shown in the figure. The segments having maximum and minimum axial stresses, respectively, are

• A. ST and PQ
• B. QR and PQ
• C. ST and RS
• D. QR and RS

Answer 1

The correct option is C ST and RS

Axial Loading Diagram
$P_{max}$ = $P_{ST}$ = 25 kN
$P_{min}$ = $P_{RS}$ = 5 kN
Hence, maximum and minimum axial stresses are in ST and RS portions because of prismatic bar.
Hence the answer is (c)
