If wicks are left in oil tubes when machinery is secured, what will happen?

They will dry out immediately
They will continue to deliver oil for some time
They will clog quickly
They will become ineffective

The correct answer is: They will continue to deliver oil for some time

When wicks are left in oil tubes while machinery is secured, they will continue to deliver oil for some time. This is because wicks have the ability to draw oil through capillary action. As long as there is sufficient oil in the tube and the machinery is intact, the wick will gradually release oil to lubricate the components. This gradual delivery helps maintain lubrication even when the machinery is not in operation, which is essential for preventing wear and ensuring that the machinery remains functional once it is restarted. In situations where wicks are designed for lubrication, it's crucial for them to remain effective over time. While wicks may not deliver oil indefinitely, the immediate effect after securing the machinery is that they will still be functional for a period of time, helping to keep internal parts lubricated until the equipment is put back into use. This gradual release is a functional aspect of their design, emphasizing the importance of proper lubrication management in mechanical systems.
