From an alloy, two specimens are machined and tested separately under tension and compression. The engineering stress-strain curves as well as the true stress-true strain curves for tension and compression are plotted in the same diagram. Identify the correct statements:
P. The engineering stress-strain curves in tension and compression are identical.
Q. The true stress-true strain curve in compression is lower than the true stresstrue strain curve in tension due to Bauschinger effect.
R. The true stress-true strain curve in tension is above the corresponding engineering stress-strain, curve.
S. The true stress-true strain curve in tension and compression are identical.
The design stress, which is more than the damaging stress, is the least unit stress that will render a member unfit for service before the end of its normal life. The design stress factor or factor of safety indicates the margin between design stress and the __________ stress.
Tresca or maximum-shear stress criteria assumes that yielding occurs when the maximum shear stress reaches a value of the shear stress in the uniaxial tension test. Assume the principal stress being σ1, σ2, σ3 where σ1 is largest, and σ3 is the smallest principal stresses. Find the value of minimum shear stress to cause yielding, given that yield stress in tension is equal to σo?
Which of the following statements regarding stress related factors is/are true and false?
1. Burnout Stress Syndrome (BOSS) is a debilirating psychological condition brought about by unrelieved work stress.
2. 'Good' and 'bad' stresses are also referred to as 'Distress' and 'Eustress' respectively.
3. It is natural and healthy to maintain optimal level of stress.
4. Rustout Stress Syndrome (ROSS) is indicative of stress overload.
5. Anxiety is a state of emotional tension characterised by Apprehension, fearfulness, and psychic pain.
If the specimen is deformed plastically beyond the yield stress in one direction, e.g., tension and then after unloading it is loaded in the opposite direction, e.g., compression, it is found that the yield stress is less than the original yield stress. This dependence of yield stress on direction loading is called ____________
When an electric current coil of a wattmeter is connected to the electric current path R and the voltage coil is connected between the electric current R path and the neutral side of the balanced three phase supply, it shows 10 kW. The line voltage along the phase sequence RYB is 400 V. The current drawn by the current path is 54 A. What is the new reading of the wattmeter if the voltage coil is connected between the lines B and the Y paths, even if the electric current coil is continuously present in the line R?

Read the given passage/argument and answer the question that follow it. Govt of India has reconfirmed their plans to go full ballistic for electric cars. An announcement which will make Elon Musk and patrons of electric vehicles super happy, India plans to allow the sale of only electric cars by 2030, which is just 12 years away. This means that petrol/diesel cars won’t be allowed on the road after 2030. This is a massive, powerful endorsement of electric, green technology, and can change transportation industry forever.  Which of the following argument can be made from above passage?
