Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसंकल्पना:
हूप प्रतिबल:
\({\sigma _1} ={\sigma _h} = \frac{{pd}}{{2t}} =\sigma \)
अनुदैर्ध्य प्रतिबल:
\({\sigma _2} ={\sigma _L} = \frac{{pd}}{{4t}} =\frac{\sigma}{2} \)
इसलिए, पतली दीवार वाले बेलनाकार दबाव बर्तन में, हूप प्रतिबल अनुदैर्ध्य प्रतिबल से दोगुना है।
Additional Information
चूँकि कि यह एक पतले बेलन की स्थिति है:
\({\sigma _r} =0\)
अधिकतम अपरूपण प्रतिबल,
= \(\tau _{max} = max\ [\frac{{\sigma _{max}}\;-\;{\sigma _{min}}}{{2}}=\frac{{\sigma _1}\;-\;0 }{2} =\frac{{pd}}{{4t}} \)
\(\tau _{max} = max\ [| \frac{{\sigma _{1}}\;-\;{\sigma _{2}}}{{2}}|, | \frac{{\sigma _{2}}\;-\;{\sigma _{3}}}{{2}}|,| \frac{{\sigma _{3}}\;-\;{\sigma _{1}}}{{2}}|]\)
\(\Rightarrow\tau_{max} = max\ [\frac{\sigma }{4}, \ \frac{\sigma }{4}, \ \frac{\sigma }{2}] \)
.\(\Rightarrow \tau_{max} = \frac{\sigma}{2}\)
\(\Rightarrow {\tau _{max}}= \frac{{pd}}{{4t}} \)
