Q. Explain the use of bare electrode?
This type of electrode is also known as plain electrode. No flux covers on this electrode. These types of electrodes are used for D.C. supply. This electrode can not prevent oxidation or any reaction with atmospheric air of molten metal. So some impurity may be added in joint and joint becomes weak in strength. Such electrode use is less.
(a) What do you understand by couple moment. Is it a free vector ? (b) A force F = 10i + 6j - 6k N performs at a position (10, 3, 4) m relative to a coordinates system. Determin
