Answer:
Proportion states that the two ratios or fractions are equal.
As per the given statement:
f the feed per revolution on an upright drilling machine is set to 1/64" and the rpm is set to 105.
Let x represents the revolutions are required for the drill to advance into the part.
By definition of proportion:
By cross multiply we have;
Multiply both sides by 64 we get;
Simplify:
Therefore, 14,280 rpm revolutions are required for the drill to advance into the part
6.5 is the answer. You can check by 6.5x8=52

Answer:
f = 33°
Step-by-step explanation:
58+89 = 147
180-147 = 33
cause these 3 angles should add up to 180°
