When the primary direct crank of a reciprocating engine is positioned ...
Explanation:
In a reciprocating engine, the primary direct crank and the secondary reverse crank are used for balancing the engine. The primary direct crank is the crankshaft that is directly connected to the piston and is responsible for converting the reciprocating motion of the piston into rotational motion.
The secondary reverse crank is another crankshaft that is positioned at a certain angle to the primary direct crank. Its purpose is to balance the engine by counteracting the forces generated by the primary direct crank.
When the primary direct crank of a reciprocating engine is positioned at 30 clockwise, the secondary reverse crank for balancing will be at 60 anticlockwise. This is because the secondary reverse crank needs to be positioned at an angle of 90 degrees to the primary direct crank. Since the primary direct crank is at 30 clockwise, the secondary reverse crank needs to be at 60 anticlockwise to achieve a 90-degree angle.
Therefore, the correct answer is option B, 60 anticlockwise.
