What is the ideal effort needed for a block-and-tackle with 6 supporting strands lifting a 600 N load?

In a block-and-tackle system, the mechanical advantage can be calculated based on the number of supporting strands. In this case, with 6 supporting strands, the mechanical advantage is 6.

To determine the ideal effort needed to lift the load, you can use the relationship between the load force and the effort force. The formula for mechanical advantage is:

Mechanical Advantage = Load / Effort

Rearranging this, we find:

Effort = Load / Mechanical Advantage

Plugging in the numbers:

Effort = 600 N / 6 = 100 N

This shows that to lift a 600 N load with 6 supporting strands, an ideal effort of 100 N is required. This calculation demonstrates how a block-and-tackle system effectively reduces the effort needed to lift heavy loads by distributing the weight across multiple strands.
