Soal Evaluasi Online Pesawat Sederhana

Explanation
Jika kita menggunakan katrol bebas dengan 1 katrol, maka gaya kuasa yang diberikan oleh katrol akan sama dengan gaya yang diberikan oleh kita. Dalam hal ini, jika kita mengangkat benda dengan gaya sebesar 100 N, maka gaya kuasanya juga akan sebesar 100 N.

Explanation
The correct answer is 1 because a fixed pulley provides mechanical advantage by changing the direction of the force applied. This means that it makes it easier to lift or move an object by allowing the force to be applied downwards instead of upwards.

Explanation
The correct answer is 60 N. When lifting an object with a fixed pulley, the force required to lift the object is equal to the weight of the object itself. In this case, the weight of the cement mixture is 60 N, so the force required to lift it is also 60 N.

Explanation
A pencatut paku is a tool that functions similarly to a stapler, which is a simple machine that uses the principle of a lever to drive a staple into a material. Just like a stapler, a pencatut paku applies force to the top of a nail or staple, driving it into a surface. This similarity in the principle of operation makes the pencatut paku comparable to a stapler or a paper clip in terms of how it works.

Explanation
The correct answer is III and IV. The principle of leverage is present in both III and IV. In III, the lever is the handle of the cart, which allows the person to easily push and move the cart. In IV, the lever is the fishing rod, which allows the person to cast the fishing line further into the water. Both examples demonstrate the use of leverage to make tasks easier and more efficient.

Explanation
Dalam pengungkitan, gaya yang diperlukan untuk mengangkat benda seberat 50 N dapat dihitung menggunakan rumus gaya pengungkit, yaitu F1 x d1 = F2 x d2. F1 adalah gaya yang diberikan pada tongkat (25 N), d1 adalah jarak dari titik tumpu ke gaya yang diberikan (1,5 m), F2 adalah gaya yang diberikan pada benda (50 N), dan d2 adalah jarak dari titik tumpu ke benda (0,5 m). Dengan menggantikan nilai-nilai tersebut ke dalam rumus, kita dapat menemukan bahwa F2 = (F1 x d1) / d2 = (25 N x 1,5 m) / 0,5 m = 75 N. Oleh karena itu, besar gaya yang digunakan untuk mengangkat benda adalah 75 N.

Explanation
The correct answer is 150 N. This is because work is calculated by multiplying the force applied to an object by the distance the object moves in the direction of the force. In this case, if the weight being lifted is 300 N, the work done would be 300 N multiplied by the distance the object is lifted. However, the distance is not given in the question, so it is impossible to determine the exact amount of work done. Therefore, the answer of 150 N is not supported by the information given in the question and cannot be considered a correct answer.

Explanation
Pada gambar di bawah ini, terdapat dua objek yang berada di atas bidang miring. Objek pertama berada di atas bidang miring dengan sudut kemiringan tertentu, sedangkan objek kedua berada di atas bidang miring dengan sudut kemiringan yang berbeda. Oleh karena itu, prinsip kerja kedua objek ini didasarkan pada prinsip bidang miring. Dengan demikian, jawaban yang benar adalah nomor 1 dan 2.

Explanation
Based on the given image, the question asks for the amount of force required to lift the load. The correct answer is 750. This implies that a force of 750 units is sufficient to lift the load.

Explanation
The correct answer is "pembuka botol". A bottle opener is a lever that has its fulcrum at one end and the load (bottle cap) between the fulcrum and the effort (force applied to open the bottle). This arrangement allows for the application of a smaller force over a longer distance to overcome a larger force over a shorter distance, making it easier to open the bottle.
