Consider the following statements regarding welded and riveted joints 1. Welded assemblies are tight and leak proof as compared with riveted assemblies. 2. Single-welded V-joint is less reliable than square butt joint. 3. Welding results in a thermal distortion of the parts, thereby inducing residual stresses. Which of the above statements is/are correct ?
Consider the following: The parallel fillet welded joint is designed for 1) tensile strength 2) compressive strength 3) bending strength 4) shear strength Which of the above is/are correct?
Quality checking of riveted joint is much expensive than that of welded joint.
The hoop stress in a riveted cylindrical shell of diameter (d), thickness (t) and subjected to an internal pressure (p) is (where $$\eta $$ = Efficiency of the riveted joint)
A joint is said to be double-riveted, triple riveted etc. accordingly to the number of sheets used.
Efficiency of a riveted joint is the ratio of its strength (max. load it can resist without failure) to the strength of the unpunched plate in
In a lap joint, if the plates are connected to each other when the joint is made with only one row of rivets then it is called double-riveted lap joint.
