Assertion (A): Concentric cylindrical helical springs are used to have greater spring force in a limited space.
Reason (R): Concentric helical springs are wound in opposite directions to prevent locking of coils under heavy dynamic loading.
The correct answer is option B: Both A and R are individually true but R is NOT the correct explanation of A.
Explanation:
Explanation for Assertion (A):
Concentric cylindrical helical springs are designed to provide a greater spring force in a limited space. They achieve this by utilizing multiple springs that are arranged concentrically. This design allows for a higher amount of spring force to be generated within the same axial length compared to a single spring. The springs are stacked one inside the other, with each spring contributing to the overall spring force. This arrangement enables the springs to generate a higher force while occupying a limited space.
Explanation for Reason (R):
The reason provided states that concentric helical springs are wound in opposite directions to prevent locking of coils under heavy dynamic loading. When a spring is subjected to heavy dynamic loading, the coils may experience torsional stresses that can cause them to lock or bind together. This locking or binding of coils can result in a loss of spring force and decreased performance of the spring.
However, this reason does not provide a correct explanation for Assertion (A). The winding direction of concentric helical springs is not primarily intended to prevent locking of coils under heavy dynamic loading. The winding direction is determined based on the desired spring characteristics, such as the direction of the applied force and the desired torque or deflection behavior. It is not specifically related to preventing coil locking.
Therefore, while both Assertion (A) and Reason (R) are individually true, Reason (R) does not provide a correct explanation for Assertion (A).
Reason (R): Concentric helical springs are wound in opposite directions to prevent locking of coils under heavy dynamic loading.
The correct answer is option B: Both A and R are individually true but R is NOT the correct explanation of A.
