Final answer:
The force that must be developed in the hydraulic cylinder AB to develop a normal force of 4.4 N in the grip is also 4.4 N, assuming ideal conditions without any mechanical advantage.
Step-by-step explanation:
To determine the force that must be developed in the hydraulic cylinder AB to develop a normal force of 4.4 N in the grip, we need to understand the principles of static equilibrium and force transmission. Assuming the mechanism is a simple lever or linkage system without any additional information on mechanical advantage, distances, or angles, a straightforward equal force transmission would indicate that the force in the hydraulic cylinder must be equal to the normal force in the grip if considering ideal conditions with no losses.
Thus, the required force in the hydraulic cylinder AB would be the same as the normal force, which is 4.4 N. Since the mechanism specifics such as dimensions and angles have not been provided, we cannot consider the mechanical advantage or leverage effect which may change the required force in the hydraulic cylinder.
