Exciting Lubricant Applications!

Which type of lubricant is typically used in the following applications?

(i) In a sewing machine. Options: A) Oil-based lubricant B) Silicone-based lubricant C) Grease-based lubricant D) Water-based lubricant

(ii) On the axle of a tractor. Options: A) Oil-based lubricant B) Silicone-based lubricant C) Grease-based lubricant D) Water-based lubricant

Final answer:

An oil-based lubricant is generally used for a sewing machine, while a grease-based lubricant is typically used for the axle of a tractor.

Explanation:

The type of lubricants used can greatly depend on the specific application. For a sewing machine, an oil-based lubricant is typically used. Oil works to reduce friction and keeps the machine running smoothly without causing damage to its inner parts. For the axle of a tractor, a grease-based lubricant is generally the better option. The thick consistency of grease makes it able to withstand heavy loads and harsh environmental conditions, offering long-lasting protection against wear and tear on the tractor's axle.
