Question 1 (True or False) Answer 1. Engineering graphics and design (EGD) impact only on technological applications than academic applications. 2. Electrical technology (electrical system and control) is purposed to build a formation in electrical, electronic, and digital principles. 3. The technological practice comprises cultural, organisational and technical aspects. 4. The view that is value-neutral suggests it is unbiased in relation to values and that its value depends on its application. 5. No one may design, manufacture, sell, or install an electric fence without adhering to the health and safety standard stipulated in the Regulations. 6. Various items of electrical machinery motors, cables, and control equipment are used collectively as a system hence the selection, preparation, installation, and protection safety when they are used separately. 7. Shear forces are sketched to measure the graphical magnitude of a shared force at any point where the load is applied. 8. Construction work involves aspects of civil technology such as earthworks, but it is not waterproof. 9. One point perspective defines the position of the eye and draws the view of the picture plane and the model. 10. The art of representing 3D objects on a 2D surface to give the right impression of the height, width, depth, and position in relation to each other is referred to as projection. 11. The hand jack works based on the force that is produced by means of presence when lifting heavy objects. 12. A hand drill is the only tool in which bevel gears of unequal size are used. [24] Question 2 2.1. Identify any rectangular object in your surrounding or locality. a) draw the object in the third orthographic angle projection. (6) b) explain in detail the steps you followed in drawing the object. (5) 2.2. Investigate suitable instruments or equipment in your context or environment that can be used to build a working homemade hydraulic system. (6) [16] Question 3 3.1.
