    Binaan lebih stabil jika  _________

    • Binaan dibuat dari besi

    • Bentuk binaan lebih cantik

    • Tapak binaan lebih luas

    • Binaan lebih tinggi

    Correct Answer
    A. Tapak binaan lebih luas
    Explanation
    A wider foundation provides more stability to a structure. By increasing the width of the foundation, the weight of the building is distributed over a larger area, reducing the pressure on the ground. This helps to prevent the structure from sinking or tilting, especially in areas with unstable soil or high winds. Therefore, a wider foundation is generally preferred as it enhances the stability of the construction.

    Antara pernyataan berikut, yang manakah benar?

    • Semakin rendah objek, semakin stabil objek

    • Kestabilan objek dipengaruhi oleh jisim.

    • Semakin besar luas tapak objek, semakin kurang kestabilan objek

    • Semakin kecil luas tapak objek, semakin stabil objek

    Correct Answer
    A. Semakin rendah objek, semakin stabil objek
    Explanation
    Semakin rendah objek, semakin stabil objek. This statement is true because when an object is lower to the ground, it has a lower center of gravity, which increases its stability. A lower center of gravity means that there is less chance for the object to topple over or lose balance. Therefore, objects that are closer to the ground are generally more stable compared to objects that are higher off the ground.

    Apakah yang mempengaruhi kestabilan?

    • Kekuatan objek

    • Luas Tapak dan Tinggi objek

    • Jenis Bahan

    • Saiz objek

    Correct Answer
    A. Luas Tapak dan Tinggi objek
    Explanation
    The stability of an object is influenced by the size of its base and its height. A larger base provides more stability as it distributes the weight of the object over a larger area, reducing the chances of it tipping over. Similarly, a lower height also contributes to stability as it lowers the center of gravity of the object, making it less likely to topple. Therefore, the combination of a larger base and a lower height increases the stability of an object.

    Struktur manakah lebih stabil? - ProProfs

    Struktur manakah lebih stabil?

    • A

    • B

    • C

    • D

    Correct Answer
    A. D
    Explanation
    Without any additional information or context, it is not possible to determine the specific criteria for stability in this question. Therefore, an explanation cannot be provided.

  • 6. 

    Semakin _____________  sesuatu binaan, semakin stabil binaan tersebut.

    • Kecil

    • Besar

    • Rendah

    • Keras

    Correct Answer
    A. Rendah
    Explanation
    The explanation for the given correct answer is that the lower or "rendah" something is built, the more stable the construction will be. This is because a lower construction has a lower center of gravity, making it less likely to topple or collapse. Additionally, a lower construction is less affected by external forces such as wind or earthquakes, further enhancing its stability.

    Bentuk manakah yang lebih stabil?

    • Sfera

    • Kuboid

    • Kubus

    • Piramid

    Correct Answer
    A. Piramid
    Explanation
    Piramid adalah bentuk yang lebih stabil karena memiliki banyak titik kontak dengan permukaan yang mendukungnya. Sisi-sisi piramid saling bertumpu dan memperkuat strukturnya, sehingga membuatnya lebih tahan terhadap perubahan dan kejutan. Sementara itu, bentuk seperti sfera, kuboid, dan kubus memiliki permukaan yang lebih sedikit untuk berinteraksi dengan lingkungannya, sehingga cenderung kurang stabil.

    Susunkan objek berikut mengikut urutan yang semakin stabil - ProProfs

    Susunkan objek berikut mengikut urutan yang semakin stabil

    • P,Q,R,S

    • S,Q,R,P

    • P, R,Q,S

    • R,P,Q,S

    Correct Answer
    A. P, R,Q,S
    Explanation
    The given objects are arranged in different orders, and the question asks for the order that is increasingly stable. Looking at the options, we can see that the object "P" is always in the first position in all the arrangements. This suggests that "P" is the most stable object. Among the remaining objects, "R" is always in the second position in all the arrangements. This indicates that "R" is the second most stable object. Following the same pattern, "Q" is in the third position and "S" is in the last position in all the arrangements. Therefore, the correct order of stability is P, R, Q, S.

    Y meningkatkan kestabilan sesuatu objek apabila dikurangkan, apakah Y?

    • Ketinggian

    • Bahan yang digunakan

    • Bentuk

    • Luas tapak

    Correct Answer
    A. Ketinggian
    Explanation
    Ketinggian dapat meningkatkan kestabilan suatu objek ketika dikurangi. Dengan mengurangi ketinggian objek, pusat gravitasi objek menjadi lebih rendah, yang dapat mempengaruhi kestabilan objek tersebut. Semakin rendah pusat gravitasi, semakin sulit bagi objek untuk terguling atau jatuh. Oleh karena itu, dengan mengurangi ketinggian suatu objek, kestabilan objek tersebut dapat meningkat.

    Dalam satu penyiasatan, dua objek iaitu silinder dan kuboid masing-masing mempunyai tinggi dan lebar yang sama. Didapati objek berbentuk silinder lebih stabil berbanding kuboid. Mengapa ?

    • Bentuk silinder lebih berat

    • Bentuk Silinder mempunyai tapak yang lebih besar

    • Bentuk silinder mengurangkan kesan tolakan angin

    • Bentuk silinder lebih menarik

    Correct Answer
    A. Bentuk silinder mengurangkan kesan tolakan angin
    Explanation
    The shape of a cylinder reduces the effect of wind resistance. This is because the streamlined shape of a cylinder allows the air to flow smoothly around it, minimizing the force of drag. In contrast, a cuboid has flat surfaces that create more resistance to the airflow, making it less stable compared to a cylinder. Therefore, the cylinder shape is more stable in this scenario.
