Questions (page 2)

Section A

Q1. लिंक ABCD का मुक्त पिंड आरेख बनाइए और चित्र में दर्शाए गए समन्वायोजन के A, B, C और D पर लगने वाले सभी प्रतिक्रिया बलों को निर्धारित कीजिए। (सभी विमाएँ mm में हैं।) 2L लम्बाई की एक क्षैतिज प्रास धरन का मुक्त सिरा, लम्बाई L और क्षेत्रफल ‘A’ की ऊर्ध्वाधर तान छड़ जो आरम्भ में तनाव रहित है, से जुड़ा है। यदि प्रास धरन का जड़त्व आघूर्ण I है, तो तान छड़ द्वारा वहन किए जाने वाले भार का निर्धारण कीजिए जब प्रास की आंतरिक अर्द्ध लम्बाई पर 'w' प्रति एकक लम्बाई का एक एकसमान वितरित भार रखा गया है। तान छड़ और प्रास धरन के लिए प्रत्यास्थता गुणांक E है।

(a) Draw the free body diagram of link ABCD and determine all reaction forces acting at A, B, C and D of the assembly shown in the figure. (All dimensions are in mm.)

(b) A horizontal beam of length 2L has its free end connected to a vertical tension rod of length L and cross-sectional area 'A', initially unstressed. If the moment of inertia of the beam is I, determine the load carried by the tension rod when a uniformly distributed load of 'w' per unit length is placed on the inner half of the beam. The modulus of elasticity for the tension rod and the beam is E.
