భావన:

  • వికృత శక్తి: ఒక వస్తువుపై ప్రయోగించే బాహ్య బలం దాని కాన్ఫిగరేషన్‌లో మార్పును కలిగిస్తుంది, అనగా వస్తువు యొక్క పొడవు, ఘనపరిమాణం లేదా ఆకారం, అప్పుడు అటువంటి బలాన్ని వికృత శక్తి అంటారు.
  • పరిపూర్ణ స్థితిస్థాపక వస్తువు: బాహ్య వికృత శక్తిని తొలగించిన తర్వాత ఒక వస్తువు తన అసలు ఆకారం మరియు పరిమాణాన్ని పూర్తిగా తిరిగి పొందితే, అటువంటి వస్తువును పరిపూర్ణ స్థితిస్థాపక వస్తువు అంటారు.
  • స్థితిస్థాపక పరిమితి: శాశ్వతంగా వికృతం కాకుండా ఏదైనా పదార్థం తట్టుకోగల గరిష్ట వికృత శక్తిని వివరించడానికి ఉపయోగించే పరిమితి (ఇది హుక్స్ నియమంలో ఉపయోగించబడుతుంది).

వివరణ:

  • పై ఉదాహరణ నుండి, బాహ్య బలం కింద ఒక వస్తువు తన అసలు స్థానాన్ని తిరిగి పొందితే, అటువంటి వస్తువులను పరిపూర్ణ స్థితిస్థాపక వస్తువు అంటారు.
  • కాబట్టి అన్నింటిలో ఎంపిక 1  సరైనది.
