Given that: Ae = effective area of the member and σy = yield stress In order to obtain the ultimate strength of a tension member, as per the plastic design concept, Aeσy is to be multiplied by Correct Answer 0.85

The maximum load capacity of the tension member is 0.85 Aeσy or 0.85 Aefy

The maximum load capacity of compression member is 1.70 Aeσac

The maximum shear capacity of beam column is 0.55 Aesfy

where

Ae = effective area of the member

σy = yield stress

σac = allowable compressive stress

Aes = effective area of the member resisting shear

Focusing on plastic pollution, the June issue of the National Geographic magazine created quite a buzz on social media, contrary to expectations after the cover featured a plastic bag submerged in an ocean with a ’Planet or Plastic?’ text on it. Ironically, the magazine itself was wrapped in a double layer of plastic. Which of the following options can be the reason for the magazine to go viral on the internet as inferred from the statements? I. It highlighted the amount of single-use plastic that enters in the world’s oceans which is a major environmental concern these days. II. National Geographic kicked off its ‘Planet or Plastic’ campaign, the magazine’s multiyear effort to raise awareness about the global plastic trash crisis through the cover. III. The magazine about ocean plastic pollution came wrapped in a plastic bag inside another plastic bag. IV. Because they realized the major flaw and announced that the magazine will no longer be shipped to readers in a plastic bag but will be sent out in a paper envelope instead.
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 ____________
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?

In the following question, the first and the last part of the sentence/passage are numbered 1 and 6. The rest of the sentence/passage is split into four parts and named P, Q, R, S. These four parts are not given in their proper order. Read the sentence/passage and find out which of the four combinations is correct. S1. Plastic bags are a major cause of environmental pollution. P. Many countries around the globe have either ban the plastic bag or Levi tax on it. Q. Plastic as a substance is non-biodegradable and thus plastic bags remain in the environment for hundreds of years polluting it immensely. R. However, the problem hasn’t been solved completely because the implementation of these measures hasn’t been as successful. S. It has become very essential to ban plastic bags before they ruin our planet completely. S6. Research shows that waste plastic bags have been a major reason for untimely animal deaths.
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.
