Solve.The longitudinal shrinkage SL (in mm) that occurs during welding is given by the formula 
where I is the welding current in amperes, L is the length of the weld in millimeters, and t is the thickness of the plate in millimeters. Suppose an electrode is welded at 175 amp, the length of the weld is 310 mm, and the plate is 10 mm thick. Calculate the longitudinal shrinkage that occurs during welding.
