Question 195General Subjects - Assistant Engineer

The correct answer is B) horsepower, torque, and speed would increase proportionally. In a variable capacity pump, an increase in the flow rate and pressurized oil supplied to a device would result in a proportional increase in the horsepower, torque, and speed of the device. This is because the higher flow rate and pressure provide more energy to the device, allowing it to generate more power and operate at a higher speed. The other answer choices are incorrect because they do not accurately describe the relationship between the pump's output and the device's performance. Decreasing speed, horsepower, and torque (option C) or increasing speed while decreasing horsepower and torque (option D) would not be the expected outcome when the pump's output is increased.
