Question: In a hydraulic press, how does increasing the force on the input piston affect the output piston?
Answer options: ✅ It proportionally increases the force on the output piston.
- It disproportionately increases the force on the output piston.
- It decreases the force on the output piston.
- It only changes the speed of the output piston.
Correct answer: It proportionally increases the force on the output piston.
Explanation: According to Pascal's Principle, pressure is transmitted equally throughout the fluid. Therefore, an increase in force on the input piston results in a proportional increase in pressure, which translates to a proportionally increased force on the output piston, given the same area ratio.
