Final answer:
The minimum force that must be applied to lift the motor using a hydraulic system is 32.53 N.
Step-by-step explanation:
To calculate the minimum force that must be applied to lift the motor using a hydraulic system, we can use the equation of force ratio:
Force ratio = area of applied force / area of load
First, convert the area of the piston of the motor to square meters: 82 cm² = 82/10000 m² = 0.0082 m². Next, substitute the values into the equation:
Force ratio = 0.0082 / 0.23 = 0.03565
Finally, multiply the force ratio by the weight of the motor to find the minimum force required to lift it:
Minimum force = 0.03565 * 94 kg * 9.8 m/s² = 32.53 N
