🔍 Key Concepts

• Use the ball float data graph to find the available operating force for a 12-inch diameter ball at a specific gravity of 0.5. • Remember that torque = force × distance (arm length), and here the distance must be in inches to get inch-pounds. • Relate each multiple-choice torque value back to the corresponding force on the float ball by dividing by the 35-inch arm.

💭 Think About

• On the graph, if you start at specific gravity 0.5 on the vertical axis, where does it intersect the 12-inch diameter curve, and what force does that give you on the horizontal axis? • Once you have the operating force from the chart, what torque do you get when you multiply that force by the 35-inch effective float arm? • If you instead work backwards from the answer choices (torque values), what operating forces do they imply, and which one best matches the force you read from the chart?

✅ Before You Answer

• Be sure you are using the correct diameter line (12 inches) on the graph, not a nearby one. • Confirm that the specific gravity value (0.5) is read on the correct vertical scale and that you trace horizontally to the curve, then vertically down to get force in pounds. • Before choosing an answer, double-check that your final unit is inch-pounds of torque, not just pounds of force.
