True or false questions.

1) For a shaft under torque, the only type of deformation, is the rotating of the cross sections with respect to each other?

2) welded assemblies generally provide greater strength at a reduced weight?

Solution

2. welded assemblies usually provide a great strength at a reduction in weight at an important advantage for moving parts of machines and transport equipment. It is a welded design, it is usually necessary to do a smaller amount of machining than for equivalent casting. The design must provide accessibility to the welds so they can be properly made and inspected. So it is the true welded assemblies provide a greater strength at a reduced weight.
