70% to passThe temper is likely to be drawn out from a chisel edge when you _______________.
Asoak it in hot oil for lengthy periods
Bhold it next to a wet grinding wheel
Cgrind the cutting angle too small
Dgrind it for long periods of time with excessive pressure
AI Explanation
The correct answer is D) grind it for long periods of time with excessive pressure. Grinding a chisel edge for long periods with excessive pressure can cause the temper to be drawn out, which means the hardness of the steel is reduced. This happens because the excessive heat generated during prolonged grinding can soften the steel, reducing its ability to hold a sharp edge. The other options, such as soaking in hot oil or grinding with a wet wheel, are not likely to cause the temper to be drawn out in the same way.
