Question

___________ is created by having equal air pressure at all wheel ends at the same time.

a) Pneumatic imbalance
b) Pneumatic balance
c) Torque imbalance
d) Torque balance

Answer 1

Pneumatic balance is achieved by having equal air pressure at all wheel ends simultaneously, which is essential for maintaining dynamic equilibrium, characterized by uniform velocity and no net torque.

Step-by-step explanation:

The term that is created by having equal air pressure at all wheel ends at the same time is known as pneumatic balance. In the context of physics, particularly when dealing with the concept of equilibrium in mechanics, torque balance is critical to ensure a system is in equilibrium—that is, it's not experiencing any net acceleration or deceleration.

When a car is in dynamic equilibrium, as shown in Figure 9.3, it is moving at constant velocity, meaning there's a balance between the applied forces and the resistive forces like air friction.

When considering torque, we must ensure that the second condition for equilibrium is met, which states that the net external torque on the system must be zero. This prevents any accelerated rotation and maintains a constant angular velocity, which is essential for equilibrium to be achieved.
