Mesin Ringkas Dan Mesin Kompleks

Explanation
A baji is a type of compact machine used for cutting an object into two parts. This statement is true because it accurately describes the purpose and function of a baji.

Explanation
The given question is in Indonesian and it asks which of the following tools does not use the principle of a simple machine with a wheel and axle. The options include car steering, a chisel, and a door handle. The correct answer is "pahat" which means chisel. A chisel does not use the principle of a wheel and axle as it is a hand tool with a sharp blade used for cutting or shaping wood, stone, or metal.

Explanation
The statement is explaining that a complex machine is a combination of more than one simple machine. This means that a complex machine is made up of multiple simple machines working together to perform a specific task. Therefore, the correct answer is true.

Explanation
The given statement states that when a small gear and a large gear are combined, they will rotate in opposite directions. This is true because when two gears are meshed together, the teeth on one gear will engage with the teeth on the other gear, causing them to rotate in opposite directions. This is a fundamental principle of gear mechanics and is commonly used in various mechanical systems. Therefore, the correct answer is true.

Explanation
The given statement refers to a "kereta sorong" or a pushcart. This can be inferred from the information provided, which mentions "tuas" (lever) and "roda dan gandar" (wheels and axles), both of which are components commonly found in a pushcart.

Explanation
The correct answer is "pembuka penutup botol." This is because the other options mentioned, such as "gerudi tangan" (hand drill) and "basikal" (bicycle), are examples of complex machines that involve multiple components and mechanisms to perform their intended functions. On the other hand, a "pembuka penutup botol" (bottle opener) is a simple machine that typically consists of a single lever or mechanism used specifically for opening bottle caps.

Explanation
The given statement states that "Takal ialah satu mesin ringkas yang boleh memudahkan dan mempercepatkan kerja serta mengurangkan daya yang digunakan." This translates to "A takal is a compact machine that can facilitate and speed up work while reducing power usage." Since this statement is true, the correct answer is True.

Explanation
The statement is false. When a wheel spins, the axle also spins in the same direction as the wheel. This is due to the fact that the axle is connected to the wheel and rotates along with it. Therefore, the axle does not spin in the opposite direction.

Explanation
The given statement is incorrect. The correct term for the point on which a lever pivots is called the fulcrum, not the object that is lifted or moved by the lever.

Explanation
The statement is saying that a ramp can be used to move an object from a lower level to a higher level. This is true because a ramp provides a sloping surface that allows objects to be easily rolled or pushed upwards, overcoming the height difference between the two levels. Therefore, the answer is true.
