FAQs on Worksheet Solutions: Carts And Wheels - 1 - Mathematics for Class 4: NCERT

1. What are the different types of wheels used in carts?
Ans. The different types of wheels used in carts include cast iron wheels, rubber wheels, pneumatic wheels, and polyurethane wheels. Cast iron wheels are durable and can handle heavy loads, rubber wheels provide a smooth ride and are ideal for indoor use, pneumatic wheels have air-filled tires that absorb shock and are suitable for outdoor use, and polyurethane wheels are non-marking and offer high load capacities.
2. How do I choose the right size of wheels for my cart?
Ans. To choose the right size of wheels for your cart, you need to consider the load capacity, the terrain or surface on which the cart will be used, and the desired maneuverability. Larger wheels are better for rough or uneven surfaces and can handle heavier loads, while smaller wheels are suitable for smooth surfaces and lighter loads. It is also important to consider the axle diameter and length to ensure a proper fit.
3. Can I replace the wheels on my cart with different ones?
Ans. Yes, in most cases, you can replace the wheels on your cart with different ones as long as they are compatible with the axle size and the load capacity requirements of your cart. It is important to choose wheels that are designed for the specific application and to properly install them to ensure optimal performance and safety.
4. How often should I check and maintain the wheels on my cart?
Ans. It is recommended to regularly check and maintain the wheels on your cart to ensure their proper functioning. This includes checking for any signs of wear or damage, inspecting the tire pressure (if applicable), cleaning the wheels to remove any debris or build-up, and lubricating any moving parts as needed. The frequency of maintenance may vary depending on the intensity of use and the operating conditions.
5. Can I use different types of wheels on the same cart?
Ans. It is generally not recommended to use different types of wheels on the same cart. Each type of wheel is designed for specific applications and has different characteristics such as load capacity, traction, and durability. Mixing different types of wheels can affect the overall stability and performance of the cart, potentially leading to safety hazards. It is best to use the same type of wheels or consult with a professional to ensure compatibility and optimal functionality.
