Can you draw a force diagram to explain how a positive caster angle makes wheels return to a straight line in a shopping kart (as an example), while a negative caster angle would have the opposite effect.

A caster angle is the angle between the vertical axis of a shopping cart's wheel and the vertical axis of the cart itself. It determines the path that the wheel will follow when the cart is pushed or pulled.
Shopping carts need caster angles to ensure stability and maneuverability. Without a caster angle, the wheel would simply move in a straight line, making it difficult to turn or navigate around obstacles.
The caster angle of a shopping cart can be measured using a protractor or angle finder. Place the wheel on a flat surface and measure the angle formed between the vertical axis of the wheel and the vertical axis of the cart.
The ideal caster angle for a shopping cart is typically between 20-30 degrees. This allows for a balance between stability and maneuverability, making it easier for customers to control the cart while shopping.
By adjusting the caster angle, you can control the wheel path of a shopping cart. A larger angle will result in a tighter turn radius, while a smaller angle will result in a wider turn radius. This allows for better control and navigation of the cart while shopping.
