Welding 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
t is the thickness of the plate in millimeters
Suppose an electrode is welded at 125 amp, the length of the weld is 270 mm, and the plate is 16 mm thick. Calculate the longitudinal shrinkage that occurs during welding. (Round to the nearest thousandth.)

- Use a calculator to help solve each problem. Alcohol absorption In one individual, the percent of alcohol absorbed into the bloodstream after drinking two glasses of wine is given by the following formula. Find the percent of alcohol absorbed into the blood after 12 hour. Pt=0.31-e-0.05t where, t is in minutesarrow_forwardThe carbon content of machine steel for gages usually ranges from 0.15% to 0.25%. Round the answers for a and b to 2 decimal places. a. What is the minimum weight of carbon in 250 kilograms of machine steel? b. What is the maximum weight of carbon in 250 kilograms of machine steel?arrow_forwardSkidding in a Curve A car is traveling on a curve that forms a circular arc. The force F needed to keep the car from skidding is jointly proportional to the weight w of the car and the square of its speed s and is inversely proportional to the radius r of the curve. a Write an equation that expresses this variation. b A car weighing 1600 lb travels around a curve at 60 mi/h. The next car to round this curve weighs 2500 lb and requires the same force as the first car to keep from skidding. How fast is the second car traveling?arrow_forward
