The Mechanical Section has introduced the \"Question of the Day\" feature, which aims to foster an active atmosphere for technical discussions and guide the direction of such exchanges. It also provides users with financial rewards, helping them experience various cool features. Multiple-choice question: The cause of deformation in fillet welds is (C). A. Transverse contraction of the weld B. Longitudinal contraction of the weld C. Uneven distribution of transverse contraction across the thickness of the weld D. Uneven distribution of longitudinal contraction across the thickness of the weld. Note: We will close this thread after 24 hours, and at that time we will announce the best response (the most helpful answer), along with the correct answer and explanations.
