Final answer:
The correct answer is a split pin, which is used with a lock washer to prevent it from turning. A split pin is a metal fastener with two tines that can be bent outward to secure it in place. Option B is correct.
Step-by-step explanation:
The correct answer is B) Split pin.
A split pin, also known as a cotter pin, is used in conjunction with a lock washer to prevent it from turning. A split pin is a metal fastener that consists of a long, looped body with two tines that can be bent outward to secure it in place. It is commonly used in machinery and automotive applications to prevent nuts, bolts, or other fasteners from becoming loose and rotating.
For example, in a car's suspension system, a split pin can be inserted through the nut and bolt that connects the control arm to the steering knuckle. The tines of the split pin are then bent outward to lock it in place, ensuring that the nut does not loosen and cause the joint to become disengaged. The lock washer further enhances the stability of the connection by providing resistance against rotation.
