The sum of 360 tons and 300 tons is 660 tons. **

TV and radio stations are not legally obligated to broadcast news, but many choose to do so as part of their commitment to serving the public interest. In some countries, there may be regulations or licensing requirements that mandate a certain amount of news programming, but this varies by jurisdiction. Ultimately, the decision to include news in their programming is up to the individual stations and their management. **

It is possible to reduce the weight from 11 tons to 749 tons on a truck. This can be achieved by unloading or removing items from the truck until the weight is reduced to 749 tons. It is important to ensure that the weight reduction is done safely and within the legal limits for the truck's capacity. Additionally, proper planning and organization are necessary to ensure that the items being removed do not disrupt the overall balance and stability of the truck. **

A transporter that can tow 3 tons is typically a heavy-duty pickup truck or a mid-size SUV with a towing capacity of at least 6,000 pounds. Vehicles like the Ford F-150, Chevrolet Silverado 1500, or Toyota Tacoma are examples of vehicles that can tow 3 tons. It is important to check the specific towing capacity of the vehicle before attempting to tow such a heavy load to ensure safety and prevent damage to the vehicle. **

A transporter capable of pulling 3 tons would typically be a heavy-duty truck or a large SUV with a high towing capacity. These vehicles are equipped with powerful engines and robust towing systems that enable them to handle the weight of 3 tons safely and efficiently. It is important to check the manufacturer's specifications and guidelines to ensure that the transporter is rated for pulling such a heavy load. **

The strength of concrete can vary depending on its composition and the specific application. However, in general, concrete can withstand a compressive strength of around 3,000 to 7,000 pounds per square inch (psi), which is equivalent to about 21 to 48 tons per square inch. This means that a typical concrete slab or structure can withstand a significant amount of weight and pressure, making it a durable and reliable building material for a wide range of construction projects. **

For an 18-ton vehicle or piece of equipment, the type of coolant needed would depend on the specific make and model of the engine. Generally, heavy-duty vehicles and equipment such as trucks, buses, and industrial machinery require a heavy-duty coolant that is designed to withstand the higher operating temperatures and stresses of these larger engines. It is important to consult the manufacturer's specifications or a professional mechanic to determine the exact type of coolant required for an 18-ton vehicle or equipment. **

The weight capacity of a bridge depends on various factors such as its design, materials used, and maintenance. Generally, bridges are designed to hold a range of weights, from a few tons for pedestrian bridges to several hundred tons for highway bridges. Engineers carefully calculate and test the weight capacity of a bridge to ensure it can safely support the intended loads. It is important to adhere to weight restrictions and guidelines to prevent damage or collapse of the bridge. **
