1.
Rekabentuk mekanikal ialah membina peranti baharu menggunakan sistem....
Correct Answer
C. Mekanikal
Explanation
The correct answer is "mekanikal". The question is asking for the system used in designing new devices, and "mekanikal" refers to mechanical design. This suggests that the process involves creating new devices using mechanical systems.
2.
Komponen mekanikal terbahagi kepada tiga kategori iaitu :
Correct Answer
A. Gerakan berputar, bersudut dan lelurus
Explanation
The correct answer is "gerakan berputar, bersudut, dan lelurus" because it accurately categorizes mechanical components into three types of movements: rotational, angular, and linear. Rotational movement refers to objects that spin or rotate around a fixed axis, angular movement involves objects changing their angle or direction without necessarily rotating, and linear movement refers to objects that move in a straight line.
3.
Gerakan berputar terdiri daripada dua jenis iaitu gerakan separa dan gerakan....
Correct Answer
lengkap
Explanation
The given answer "lengkap" is correct because the question states that "Gerakan berputar terdiri daripada dua jenis iaitu gerakan separa dan gerakan...." which means that there are two types of rotational motion, one being "separa" (incomplete) and the other being "lengkap" (complete). So, "lengkap" is the appropriate term to complete the sentence and provide the correct answer.
4.
Contoh komponen mekanikal yang menggunakan gerakan bersudut adalah aci sesondol dan pautan.
Correct Answer
A. True
Explanation
The given statement is true. Mechanical components such as a crankshaft and linkage utilize angular motion. These components are designed to convert linear motion into rotational motion or vice versa. A crankshaft, for example, is used in engines to convert the reciprocating motion of the pistons into rotational motion, which drives the wheels of a vehicle. Similarly, a linkage is a mechanism that connects two or more components and allows them to move in a specific way, often involving angular motion. Therefore, the statement is correct.
5.
Pilih DUA (2) komponen mekanikal di bawah yang mengaplikasikan GERAKAN LELURUS.
Correct Answer(s)
B. Gelongsor
C. Rantai
Explanation
The correct answer is gelongsor and rantai. Both gelongsor and rantai are mechanical components that apply linear motion or straight-line movement. Gelongsor, also known as a slide or slider, is a mechanical component that allows objects to move in a straight line along a surface. Rantai, which means chain, is a mechanical component that consists of a series of interconnected links and is used to transmit motion or power in a straight line. Therefore, gelongsor and rantai are the correct answers as they both apply straight-line motion.
6.
Sila susun urutan proses kerja sistem mekanikal yang paling tepat di bawah :
Correct Answer
D. 1. input 2. proses 3. output
Explanation
The correct order for the mechanical system's workflow is to first have an input, then carry out the process, and finally produce an output. This sequence ensures that the system receives the necessary information or resources (input), performs the required actions or transformations (process), and generates the desired result or outcome (output).
7.
Di dalam ujian penilaian sesebuah produk, ciri-ciri yang berikut diambilkira KECUALI...
Correct Answer
D. HARGA YANG MURAH
Explanation
The given answer, "HARGA YANG MURAH" (cheap price), is the exception among the listed characteristics that are considered in the product evaluation. The other three characteristics, "KETEGUHAN" (durability), "KEKUATAN CANTUMAN" (strength of the joint), and "DAYA PENYERAPAN" (absorption capacity), are factors that are typically taken into account when assessing a product's quality or performance. However, the price of a product, although important to consumers, is not directly related to its inherent qualities or performance.
8.
Di dalam komponen asas sebuah basikal, peringkat INPUT di laksanakan oleh bahagian gear dan rantai.
Correct Answer
B. False
Explanation
The given statement is false. In the basic components of a bicycle, the gear and chain are not responsible for the input stage. The input stage is typically performed by the rider who provides the force to pedal the bicycle. The gear and chain are part of the transmission system that transfers the input force from the rider to the wheels of the bicycle, allowing for different speeds and torque.
9.
Selepas Ujian Kestabilan dilakukan terhadap sebuah monopod, penambahbaikan yang mungkin boleh dibuat adalah (PILIH SATU JAWAPAN SAHAJA)
Correct Answer
A. Menambahbaik bahan komponen monopod
Explanation
The possible improvement that can be made after conducting the Stability Test on a monopod is to improve the material components of the monopod. This suggests that the current materials used may not be strong or durable enough to provide stability, and therefore, upgrading or replacing these components can enhance the stability of the monopod.
10.
Di antara jenis ujian penilaian yang boleh dilakukan ke atas sesebuah produk yang ingin ditambahbaik adalah
Correct Answer
C. Ujian kestabilan
Explanation
Ujian kestabilan adalah penting dalam menilai produk yang ingin ditambahbaik kerana ia akan menentukan keupayaan produk untuk mengekalkan prestasi dan kualiti yang dikehendaki dalam jangka masa yang lama. Ujian ini akan menguji kebolehan produk untuk menahan tekanan, getaran, suhu, kelembapan, dan faktor-faktor lain yang boleh mempengaruhi prestasi produk. Dengan melakukan ujian kestabilan, pengeluar dapat mengenal pasti kelemahan produk dan membuat penambahbaikan yang diperlukan untuk meningkatkan kualiti dan kebolehpercayaan produk.
