The __________ factor is the relative change in resistance divided by relative change in length i.e., the definition of strain.

The __________ factor is the relative change in resistance divided by relative change in length i.e., the definition of strain. Correct Answer Gauge

Strain gauge is the ratio of relative change in electrical resistance R, to the mechanical strain ε. Metal strain gauges have a gauge factor of about 2; thus a strain of 0.1% would cautilise a 0.24 Ω change in a 120 Ω strain gauge.

The true strain rate is given as ϒ, and conventional strain rate is given as ε. The engineering strain is equal to e. The relationship between conventional strain rate and true strain rate is _______
To maintain the constant true strain rate of a sample, the crosshead velocity should increase with the increase in the length of the specimen. What will be the optimum velocity with the change in length to keep the true strain rate constant? (True strain rate=ϒ, L=length of sample, t=time).
Assertion (A) From its inception, the study of organisational change has noted the fact that many participants respond with dogged resistance to altering the status quo. Since the industrial revolution began, workers have at times sought, occasionally in extremely violent fashion, to block the introduction of new technology.
Reason (R) Such behaviour may be either overt or covert. Overt resistance may take the form of employees deliberately failing to do the things necessary for successful change or simply being unenthusiastic about the change.
Covert resistance can be more detrimental to change than open resistance because it is harder to identify and eliminate.
The change in resistance of a metal wire owing to strain is due to
S1: Change in dimension of wire expressed by factor (1-2µ)
S2: Change in resistance ?
A passage is given with five questions following it. Read the passage carefully and select the best answer to each question out of the given fouralternatives. Teaching about compassion and empathy in schools can help deal with problems of climate change and environmental degradation,” says Barbara Maas, secretary,
Standing Committee for Environment and Conservation, International Buddhist Confederation (IBC). She was in New Delhi to participate in the IBCs governing
council meeting, December 10-11, 2017. “We started an awareness campaign in the year 2005-2006 with H H The Dalai Lama when we learnt that tiger skins were
being traded in China and Tibet. At that time, I was not a Buddhist; I wrote to the Dalai Lama asking him to say that this is harmful and he wrote back to say, “We
will stop this.” He used very strong words during the Kalachakra in 2006, when he said, If he sees people wearing fur and skins, he doesnt feel like living. This sent
huge shock waves in the Himalayan community. Within six months, in Lhasa, people ripped the fur trim of their tubba, the traditional Tibetan dress. The messenger was ideal and the audience was receptive,” says Maas who is a conservationist. She has studied the battered foxs behavioral ecology in Serengeti,Africa. She heads the endangered species conservation at the Nature and Biodiversity Conservation Union (NABU) International Foundation for Nature, Berlin. “I metSamdhong Rinpoche, The Karmapa, HH the Dalai Lama and Geshe Lhakdor and I thought, if by being a Buddhist, you become like this, I am going for it, “says Maas, who led the IBC initiative for including the Buddhist perspective to the global discourse on climate change by presenting the statement, The Time to Act is Now: aBuddhist Declaration on Climate Change, at COP21 in Paris. “It was for the first time in the history of Buddhism that leaders of different sanghas came together to take a stand on anything! The statement lists a couple ofimportant things: the first is that we amass things that we dont need; there is overpopulation; we need to live with contentment and deal with each other and theenvironment with love and compassion,” elaborates Maas. She is an ardent advocate of a vegan diet because “consuming meat and milk globally contributes more toclimate change than all "transport in the world.” Turning vegetarian or vegan usually requires complete change of perspective before one gives up eating their favorite food. What are the Buddhist ways to bringabout this kind of change at the individual level? “To change our behavior, Buddhism is an ideal vehicle; it made me a more contented person,” says Maas, who grewup in Germany, as a sausage chomping, meat-loving individual. She says, “If I can change, so can anybody”. Why did Ms. Barbara Mass say “If I can change, so can anybody”?

The gain of the differential amplifier is -125. Assume the voltage applied to bridge circuit Vdc=+10v and the unstrained resistance of four element of strain gage is 200Ω. When a certain weight is placed on the platform, the output voltage Vo=5v. Determine the change in resistance of each strain gage for analog weight scale. (Assuming the output is initially nulled).
