Assertion (A): For a radial engine containing four or more cylinders, ...
The radial engine has resulted in a total resultant primary force of fixed magnitude viz. and directed along the first crank. Thus this fixed magnitude force ―rotates‖ along with the first crank. Such a resultant force can therefore readily be balanced out by an appropriate mass kept on the crank. Therefore it is possible to get complete balance of the primary forces.
The inertia forces reveals that for even number of cylinders (n > 2) i.e., for four, six, eight etc. cylinders the secondary forces are also completely balanced out.

Assertion (A): For a radial engine containing four or more cylinders, ...
Explanation:
The given assertion states that for a radial engine with four or more cylinders, the secondary forces are in complete balance. This is true because in radial engines, the secondary direct and reverse cranks form a balanced system.
Reasoning:
- Primary Forces: In a radial engine, the primary forces are balanced due to the equal and opposite forces exerted by the pistons in each cylinder.
- Secondary Forces: The secondary forces in a radial engine are caused by the non-uniform motion of the pistons as they move in a circular path. These forces can cause vibration and imbalance in the engine.
- Direct and Reverse Cranks: In a radial engine, the secondary forces are minimized by arranging the cylinders in a radial pattern around the crankshaft. The direct and reverse cranks are positioned in such a way that their forces cancel each other out, leading to complete balance of the secondary forces.
- Balance of Forces: As a result of the arrangement of cylinders and cranks in a radial engine, the secondary forces are effectively balanced, ensuring smooth operation of the engine.
Therefore, both the assertion and the reason are true, and the reason provides a correct explanation for the assertion.
