Mixed Format $$E _ { LIN E } = \sqrt { E _R ^ { 2 } + E _X ^ { 2 } }$$

Short Answer

Mixed format: $$E _ { LIN E } = \sqrt { E _R ^ { 2 } + E _X ^ { 2 } }$$ (with a space between the whole number and the numerator) Fraction format: $1 /4$
Reduce all fractions. A motor commutator inches in diameter is turned down to remove a flat spot. If $3 / 64$ inch is removed from the surface, find the finished diameter.
