Question
Download Solution PDFकिसी धातु शीट के ब्लैंकिंग ऑपरेशन में बल की आवश्यकता 10 kN है। शीट की मोटाई T और ब्लैंक किए गए भाग का व्यास D है। समान सामग्री और समान परिस्थितियों के लिए, यदि ब्लैंक किए गए भाग का व्यास बढ़ाकर 1.7 D कर दिया जाता है और शीट की मोटाई घटाकर 0.5 T कर दी जाती है, तो आवश्यक नया ब्लैंकिंग बल क्या होगा?
Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFसिद्धांत:
ब्लैंकिंग बल दिया गया है:
\( F = \tau \times \text{परिमाप} \times \text{मोटाई} \)
एक वृत्ताकार ब्लैंक के लिए, परिमाप \( \pi D \) और मोटाई \( T \) है।
इसलिए, \( F = \tau \times \pi D \times T \)
दिया गया है:
प्रारंभिक ब्लैंकिंग बल = 10 kN
प्रारंभिक व्यास = \( D \), प्रारंभिक मोटाई = \( T \)
नया व्यास = \( 1.7D \), नई मोटाई = \( 0.5T \)
गणना:
नया बल,
\( F_{\text{नया}} = \tau \times \pi \times (1.7D) \times (0.5T) = \tau \times \pi D T \times (1.7 \times 0.5) \)
\( F_{\text{नया}} = F_{\text{पुराना}} \times 0.85 = 10 \times 0.85 = 8.5~\text{kN} \)
