How do big trucks carry heavy things?

Big trucks carry heavy things because they are strong. Their wide wheels hold up the load. The engine pulls and pushes hard. The back is flat and tough.

Big trucks can carry heavy things because they are built very strong. Their hard body holds the load, and many big wheels share the weight, so one wheel does not get squished too much. A strong motor makes the truck move. It is like when you carry toys in a sturdy wagon instead of in your arms.

Big trucks carry heavy things by using a powerful engine, which makes the wheels turn with lots of force. Their frame, the strong metal bottom part, holds the weight. Many tires spread the load over the road, and brakes help slow the truck safely. Some trucks also use low gears, which make them move slowly but pull harder. Fun fact: a loaded semi truck can weigh as much as about 20 cars.
