Which of the following is the cylinder bore area necessary for an application with 80 psi requiring 800 lbs force?

To determine the cylinder bore area required to generate a specific force at a given pressure, you can use the formula that relates force, pressure, and area. The formula is:

[ \text{Force} = \text{Pressure} \times \text{Area} ]

To find the area, you can rearrange the formula:

[ \text{Area} = \frac{\text{Force}}{\text{Pressure}} ]

In this case, you need to calculate the area in square inches for a force of 800 lbs at a pressure of 80 psi.

Substituting the values into the equation gives:

[ \text{Area} = \frac{800 \text{ lbs}}{80 \text{ psi}} ]

When you perform the calculation:

[ \text{Area} = \frac{800}{80} = 10 \text{ square inches} ]

This calculation shows that to produce a force of 800 lbs at a pressure of 80 psi, the cylinder should have a bore area of 10 square inches. Hence, this makes the correct answer, as it directly aligns with the parameters set by the question and confirms the necessary bore area required for the application.
