The
shearing strength of a rivet is 50N
एक कीलक की कतरनी ताकत 50N है। यदि कीलक का व्यास दोगुना कर दिया जाए, तो इसकी कतरनी ताकत होगी:
The
shear strength, tensile strength and compressive strength of a rivet joint are
100 N, 120 N and 150 N respectively. If strength of the unriveted plate is 200
N, the efficiency of rivet joint is
एक कीलक जोड़ की कतरनी शक्ति, तन्य शक्ति और संपीड़न शक्ति क्रमशः 100 N, 120 N और 150 N है। यदि अनरिवेटेड प्लेट की ताकत 200 N है, तो रिवेट जोड़ की दक्षता है
