Determine the maximum load that can be moved with a relief valve setting of 1500 psi and a cylinder with a 3 inch bore.

To determine the maximum load that can be moved with a relief valve setting of 1500 psi and a cylinder with a 3-inch bore, you first need to calculate the area of the cylinder and then apply the pressure to find the force that can be generated.

The area (A) of a cylinder can be calculated using the formula:

[ A = \pi \times \left( \frac{d}{2} \right)^2 ]

Where (d) is the diameter of the cylinder. For a cylinder with a 3-inch bore:

1. Convert the diameter from inches to feet (if necessary for unit consistency), but here it's more straightforward to keep it in inches since we will compute the pressure in psi.

2. Calculate the radius: ( \frac{3}{2} = 1.5 ) inches.

3. Calculate the area:

[ A = \pi \times (1.5)^2 = \pi \times 2.25 \approx 7.0686 , \text{square inches} ]

Next, apply the relief valve pressure to the area to find the maximum force (load) the cylinder can generate:

[ F = P \times A ]
