A concrete column 300mm x 300mm in section, is reinforced by 10 longitudinal 20mm diameter round steel bars. The column carries a compressive load of 450KN. Find load carried and compressive stress produced in the steel bars and concrete. Take Es = 200GN/m2 and Ec = 15GN/m2 . |
|
Answer» Cross sectional Area of column = 300 × 300 = 90000mm2 Area of steel bars As = 10 × (\(\pi\)/4)(20)2 = 3141.59mm2 Area of concrete = 90000 – 3141.59 = 86858.4 mm2 Each component (concrete and steel bars) shorten by the same amount under the compressive load, and therefore Strain in concrete = strain in steel \(\sigma\)c/Ec = \(\sigma\)s/Es Where \(\sigma\)c, \(\sigma\)s are stress induced in concrete and steel respectively \(\sigma\)s = (Es \(\sigma\)c)/Ec = (200 × 109 /15 × 109 ) \(\sigma\)c = 13.33 \(\sigma\)c Further, Total load on column = Load carried by steel + load carried by concrete P = \(\sigma\)s.As + \(\sigma\)c.Ac 450 × 103 = 13.33\(\sigma\)c × 3141.59 + \(\sigma\)c. 86858.4 = 128735.8 \(\sigma\)c \(\sigma\)c = 3.59 N/mm2 \(\sigma\)s = 13.33 × 3.59 = 46.95 N/mm2 Load carried by concrete Pc = \(\sigma\)cAc = 3.59 × 86858.4 = 311821.656 N = 311.82KN Load carried by steel Ps = \(\sigma\)sAs = 46.95 × 3141.59 = 147497.65 N = 147.49 KN |

How do the workers of a shoe factory in Japan demonstrate their protest?जापान में जूता बनानेवाली कंपनी के कर्मचारियों ने अपना विरोध किस प्रकार से प्रदर्शित किया? |
|
Answer» The writer has cited a very good example from Japan. In that country when the workers of a shoe factory want to show their protest, they make shoes of different sizes of right foot only. This is the novel idea of demonstrating our protest. They wait for settlement of their issues. When their issues are settled , they make shoes of left foot. In this way the workers complete the pairs and compensate the initial loss suffered by the owner. लेखक ने जापान से एक अत्यंत सटीक उदाहरण पेश किया है। उस देश में जब जूता बनानेवाली कंपनी के कर्मचारियों ने अपना विरोध जताना चाहा, तो उन्होंने विभिन्न आकार के मात्र दाएँ पैर के जूते बनाए। यह हमारे विरोध जताने का बौद्धिकता से परिपूर्ण विचार है। उन्होंने अपने मुद्दों के समाधान का इंतजार किया। जब उनके मुद्द निपट गए तो उन्होंने बाएँ पैर का जूता बनाकर जोड़ी तैयार कर दिया और इस तरह से जूतों का जोड़ा तैयार कर कर्मचारियों ने कंपनी को हुई हानि का भरपाई कर दिया। |

According to the writer how can we express our protests without causing any difficulties to others?लेखक के अनुसार हम अपना विरोध प्रदर्शन किस प्रकार से करें ताकि दूसरों को किसी प्रकार की परेशानी का सामना न करना पड़े? |
|
Answer» The writer thinks that we should demonstrate our protest without causing any difficulty to others. Satyagraha or hunger strike is the greatest weapon given by Mahatma Gandhijee, the father of our nation. Satyagraha or hunger strike is nonviolent in nature. It never causes difficulty for others. It is the best method to show our protests because only the protesters suffer here. No harm or damage is caused to the person against whom it is adopted. Gandhijee made our country free with help of this powerful weapon. लेखक मानते हैं कि हम किसी को परेशान किए बिना ही अपना विरोध प्रदर्शन कर सकते हैं। सत्याग्रह और भूख हड़ताल, ये दो सशक्त हथियार हमें गांधीजी ने दिए हैं जो कि अहिंसा की प्रकृति का है। इसके द्वारा किसी को भी परेशानी नहीं होता है। हमारे द्वारा विरोध प्रदर्शित करने का यह सर्वोपयुक्त हथियार है जिसके चलते किसी दूसरे को कोई परेशानी नहीं होती जबकि इससे विरोध करनेवाला ही प्रभावित होता है। इससे उस आदमी को कोई हानि अथवा नुकसान नहीं होता है जिसके विरोध में इसका उपयोग किया जाता है। गांधीजी ने इसी सशक्त हथियार के माध्यम से हमारे देश को आजाद कराया था। |

We may follow the path of Satyagraha or hunger strike taught by Gandhi jee. हम अपने विरोध को दर्ज कराने के लिए एक उपयुक्त रास्ते का चयन कर लें। हम इस बात को अपने दिमाग में बिठाकर चलें कि हमारे विरोध से किसी दूसरे पर कोई असर नहीं पड़ेगा। इसके साथ ही यह भी ध्यान में रखना जरूरी है कि सार्वजनिक संपत्ति को किसी प्रकार का नुकसान न हो। हम गांधीजी द्वारा बताए गए मार्ग सत्याग्रह और असहयोग अथवा भूख हड़ताल को अपने विरोध के लिए अपनाएँ। |

Why are we not pacing up with other Super powers?हम अन्य सुपर पावर के साथ कदम से कदम मिलाकर क्यों नहीं चल पाते हैं? |
|
Answer» The Indiana are far superior to the other super powers. But the grandeur of the big and small is always neglected. In our country no value is given to the small. Such kind of thinking has hampered our glory. हम भारतीय विश्व के अन्य सुपर पावर देशों से बहुत आगे हैं। लेकिन इस विशाल देश के अन्तर्गत बौद्धिक विकास को बड़ों और छोटों के चक्कर में पड़कर नजरअंदाज कर दिया जाता है। हमारे देश में छोटों को कोई महत्त्व नहीं दिया जाता है। इस तरह की विचारधारा हमारे हुनर की चमक को नष्ट कर देती है। |

Whom does the writer call uncivilized?लेखक ने किसे असभ्य मानव कहा है? |
|
Answer» The writer call the people with muscle power uncivilized. The proverb- ‘ Pen is mightier than sword’, is applicable to such people.

Even a gossip or a chit-char in a company creates:(a) a high hearing power(b) noise pollution(c) a sound music(d) a jarring sound |
|
Answer» (b) noise pollution |
|
| 2026. |
How does noise pollution affect our life?किस प्रकार ध्वनि प्रदूषण हमारे जीवन को प्रभावित करता है? |
|
Answer» Human ear can receive the sound of normal rage. The sound received beyond the fixed limit may be jarring and cause damage to our hearing sense organs. The heavy vehicles make our unbearding. The truck drivers blow horns without purpose and constantly. It may create problems for the heart patients. Our neighbors may be serious students or sick persons. Playing the tape recorder and any other instrument may disturbed them. Students may get disturbance in their concentration. मनुष्य का कान सामान्य तीव्रता की ध्वनि को ही सुन सकता है। एक निश्चित सीमा से अधिक तीव्रता वाली ध्वनि को ग्रहण करने से हमारी श्रवण शक्ति पर इसका बुरा प्रभाव पड़ता है और यह उसे नुकसान पहुँचा सकता है। भारी वाहनों के द्वारा मचाए गए शोर हमारे लिए असह्य होते हैं। ट्रकों के ड्राइवर बिना किसी उपयुक्त कारण के ही लगातार होर्न बजाते रहते हैं। यह हृदय की बीमारियों से ग्रसित मरीज के लिए यह घातक साबित होता है। हमारे पड़ोस में अपने भविष्य के प्रति कोई सतर्क छात्र और बीमार आदमी भी हो सकता है। टेप रिकार्डर और अन्य वाद्य यंत्र उनके लिए व्यवधान खड़ा कर सकते हैं। छात्र अपने एकाग्रता में इनके कारण बाधा का अनुभव करते हैं। |
