To determine the effort needed, it is essential to apply the principles of mechanical advantage. In this case, the system involves a load being lifted or moved, taking into account the dimensions of the diameters involved and the load being applied.

The relationship among the effort, load, and the diameters can be governed by the formula:

[

\text{Effort} = \frac{L \times LD}{\text{Mechanical Advantage}}

]

Where:

  • ( L ) is the load applied (3050 lbs in this scenario).

  • ( LD ) is the length diameter in relation to the system (0.255 in this case).

Mechanical advantage is generally calculated using the radii or diameters involved in the system. Here, the relevant diameters are ( d ) and ( D ), being 0.554 inches and 3.25 inches respectively. By determining the ratio of the diameters (or radii) as

[

\frac{D}{d} = \frac{3.25}{0.554}

]

A mechanical advantage can be established. Once the mechanical advantage is calculated, it can then be used in the effort equation to find the exact amount of effort, leading to
