Which problem might be caused by aerodynamic forces on windshield wipers?

When considering the impact of aerodynamic forces on windshield wipers, reduced wiper blade loading pressure is a significant concern. Aerodynamic forces can create a lifting effect on the wiper blades when the vehicle is in motion, which may lead to a situation where the blades do not press down adequately against the windshield.

This reduction in loading pressure can result in diminished contact between the wiper blades and the glass, making them less effective at clearing water or debris. If the blades cannot maintain proper contact due to aerodynamic lift, it compromises their overall performance, leading to streaks or spots remaining on the windshield and ultimately affecting visibility.

Increased wiper blade tension would not align with the effects of aerodynamic forces, as tension typically means more pressure is being applied to keep the blade against the windshield. Increased power consumption would be associated with factors like motor strain from managing excessive wiper operations or faster speeds rather than the effect of aerodynamic forces. Similarly, decreased wiping efficiency can occur; however, this is more a consequence of reduced loading pressure rather than a direct representation of aerodynamic force impact.

Therefore, understanding how aerodynamic forces can change the pressure dynamics on wiper blades helps clarify why reduced wiper blade loading pressure is the most appropriate answer.
