Correct Answer
A. PengungkitExplanation
A pengungkit (lever) is a simple machine that can be used to amplify force and make it easier to remove a nail from a wall. By applying force to one end of the lever, the other end exerts a greater force on the nail, allowing it to be pulled out more easily. This makes pengungkit the most suitable option for removing a nail from a wall.Rate this question:

-
Beban berada di antara titik tumpu dan kuasa
-
Kuasa berada di antara titik tumpu dan beban
-
Titik tumpu, beban, dan kuasa berada pada satu tempat
Correct Answer
A. Beban berada di antara titik tumpu dan kuasaExplanation
The correct answer is "beban berada di antara titik tumpu dan kuasa." This means that the load is located between the pivot point and the effort or force applied. In a lever system, the load is the object being moved or lifted, the pivot point is where the lever rotates, and the effort is the force applied to move the load.Rate this question:

Correct Answer
A. Bidang miringExplanation
The correct answer is "bidang miring." A tangga is a simple machine that utilizes the principle of a inclined plane. It is used to make it easier to climb up or down a height by spreading the effort over a longer distance. By increasing the length of the slope, the amount of force required to move an object vertically is reduced. This principle is commonly seen in ramps, stairs, and sloping roads.Rate this question:

Correct Answer
A. SekrupExplanation
The principle of inclined plane is applied to the screw. The screw is a simple machine that consists of an inclined plane wrapped around a cylindrical shaft. It allows for the conversion of rotational motion into linear motion, making it easier to lift or move objects. The inclined plane of the screw allows for a longer distance over which the force is applied, reducing the amount of force needed to accomplish the same work.Rate this question:

-
Katrol ganda
Correct Answer
A. Katrol tetapExplanation
Sumur timba memanfaatkan pesawat sederhana berupa katrol tetap. Katrol tetap adalah jenis katrol yang tidak dapat bergerak. Dalam hal ini, katrol tetap digunakan untuk mengangkat timba dengan mengurangi beban yang diperlukan oleh pengguna. Ketika timba ditarik, katrol tetap akan memutar dan mengurangi gaya yang diperlukan untuk mengangkat timba. Dengan demikian, katrol tetap mempermudah proses pengambilan air dari sumur timba.Rate this question:

Bagian pada sekrup yang menggunakan prinsip kerja bidang miring yaitu nomor . . . .
-
I
-
II
-
III
-
IV
Correct Answer
A. IExplanation
The correct answer is I. The explanation for this is that the part of the screw that uses the principle of inclined plane is the thread. The thread of the screw is a continuous helical ridge that winds around the cylindrical body of the screw. When the screw is rotated, the inclined plane of the thread allows it to move through a solid material, such as wood or metal, by converting rotational motion into linear motion. This makes it easier to drive the screw into the material or to create a mechanical advantage for lifting heavy objects.Rate this question:

Saat mengangkat benda dengan katrol, gaya yang diperlukan bertumpu pada . . . .
-
Gaya gesek dan berat badan
-
Gaya gesek dan gaya tarik
-
Gaya tarik dan berat badan
-
Gaya gravitasi dan berat badan
Correct Answer
A. Gaya tarik dan berat badanExplanation
When lifting an object with a pulley, the force required is supported by the tension force in the rope (gaya tarik) and the weight of the object (berat badan). The tension force in the rope pulls upward, counteracting the downward force of gravity on the object. Therefore, the correct answer is "gaya tarik dan berat badan."Rate this question:

Roda pada sepeda bekerja menggunakan prinsip . . . .
-
Bidang miring
-
Roda berporos
-
Pengungkit
-
Katrol
Correct Answer
A. Roda berporosExplanation
The correct answer is "roda berporos". This is because the phrase "roda berporos" translates to "axle wheel" in English. In a bicycle, the wheels are attached to the axle, which allows them to rotate and move the bike forward. Therefore, the working principle of the bicycle wheels is based on the concept of having an axle or pivot point, which is represented by the term "roda berporos".Rate this question:

Correct Answer
A. Bidang miringExplanation
The correct answer is "bidang miring" because the tool mentioned in the question works using the principle of an inclined plane. An inclined plane is a flat surface that is at an angle to the horizontal surface. It allows for the movement of objects along its surface with less force required compared to lifting the object vertically.Rate this question:

-
Rangkap
-
Takal
Correct Answer
A. RangkapExplanation
The correct answer is "rangkap." In the given question, it is mentioned that Derek di pelabuhan menggunakan jenis katrol, which translates to "Derek at the port uses a type of pulley." The word "rangkap" means "compound" or "multiple" in Indonesian. Therefore, it can be inferred that Derek is using a compound pulley system, where multiple pulleys are used to increase mechanical advantage and make lifting heavy loads easier.Rate this question:

-
Gunting, palu
-
Pinset, sapu
-
Kapak, psau
-
Grobak, kursi roda
Correct Answer
A. Kapak, psauExplanation
The correct answer is "Kapak, psau". Both a kapak (axe) and psau (saw) are examples of tools that work based on the principle of a simple inclined plane. The blade of an axe is a sloping surface that allows for easier splitting of wood by reducing the force required. Similarly, the teeth of a saw are also inclined, which helps to cut through materials more efficiently by reducing friction.Rate this question:

Katrol ganda
Correct Answer
A. Katrol gandaExplanation
The correct answer is "katrol ganda". This is because a "katrol ganda" refers to a system of pulleys that consists of multiple pulleys connected by a single rope or cable. In this system, the load is attached to one end of the rope, and the effort is applied to the other end. The use of multiple pulleys in a "katrol ganda" system allows for a mechanical advantage, making it easier to lift heavy loads.Rate this question:
