Consider the following statement: 1. Initial load tests and routine load tests are carried out on test piles and working Piles, respectively. 2. In a pile load test, the allowable load can be taken equal to half the ultimate load at which the total settlement amounts to one-tenth of the pile diameter. 3. In a pile load test, the allowable load can be taken equal to two-thirds of the total toad which causes a plastic settlement of 6 mm. Which of the above statements are correct?
Read the given paragraph carefully and decide which of the conclusions given in the options logically follows from the paragraph. The alarming level of pesticide and insecticide residue is found in fruits and vegetables sold in the market, causing public unrest. The reason is farmers are being forced to use affordable chemical pesticides in large amounts to protect the harvest. The pests, after some time, get immune to chemicals and hence farmers are forced to use more harmful chemicals to exterminate them. The government is, however, planning to ban the use of some harmful chemicals as they cause health issues, thus breaking this vicious circle.
An axial residual compressive stress due to a manufacturing process is present on the outer surface of a rotating shaft subjected to bending. Under a given bending load, the fatigue of the shaft in the presence of the residual compressive stress is ____________
Residual stresses are also known as locked-in stresses.
Residual stresses can also be calculated the same way as the stresses due to the external loads is calculated.
