If it is necessary to compute a bend allowance problem and bend allowance tables are not available, the neutral axis of the bend can be. represented by the actual length of the required material for the bend. found by adding approximately one-half of the stock thickness to the bend radius. found by subtracting the stock thickness from the bend radius.

Which of the following statements is true?. There are two basic types of DC motors: series and compound. In the compound motor, the field windings, consisting of relatively few turns of heavy wire, are connected in parallel with the armature winding. In the series motor, the field windings, consisting of relatively few turns of heavy wire, are connected in series with the armature winding.
