Which of the following stresses are associated with the tightening of a nut on a bolt? P. Crushing and shear stress in threads Q. Bending stress due to the bending of bolt R. Torsional shear stress due to frictional resistance between the nut and the bolt Select the correct answer using the codes given below: Correct Answer P and Q

Bending stress comes when there is some kind of eccentric load. Torsional stress will come when the nut is rotating. Shear stress will come in tightening of a nut on bolt.

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?

Consider the following statements in respect of arched construction made of voussoirs: 1. The superimposed load is transferred to the sidewalls only by the strength of cohesion of the mortar between the voussoirs. 2. The arch may fail under crushing when the compressive stress or thrust in it exceeds the safe crushing strength of the voussoir material. 3. Every element in the arch is subjected to compression only. 4. Failure of the arch due to the sliding of any voussoir past the adjacent one due to transverse shear can be avoided by reducing the height of the voussoirs. Which of the above statements are correct?
