Torque is the twisting force that tends to cause rotation. It is the measure of how much a force acting on an object causes that object to rotate. Visit to learn how to calculate torque along with its formula, meaning and applications.
von Mises stress is a scalar quantity obtained from the stresses acting on any structure. This helps us to evaluate the yielding(or failure) of a ductile material. Principal stresses, on the other hand, are the components of stresses when the basis of other stress tensor are zero. 欢迎搜索...
