4.1 Identify the turning bank component as shown in FIGURE 4.1 - NSC Mechanical Technology Fitting and Machining - Question 4 - 2021 - Paper 1

The CORRECT statement is: B. Verwyder snyles vir die masjien te beweeg nie.

Absolute programming refers to the method where each position of the tool is defined in relation to a fixed origin point, allowing it to be programmed without reference to previous positions.

Tool change and automation occur when masjien aangeskakel word.

The indenter/ball of the Brinell hardness tester is made from Koper.

The type of tester shown in FIGURE 4.6 is a Hardheidstoetsers.

Tensile stress refers to the external pulling force per unit area within a material, causing it to elongate. It can be expressed mathematically as:

$\sigma = \frac{F}{A}$

where

• $\sigma$ = tensile stress,
• $F$ = applied force,
• $A$ = cross-sectional area.

The type of stress that causes deformation in the beam as shown in FIGURE 4.8 is Drukspanning.

Connections should be used with caution to ensure structural integrity and load-bearing capacity based on the materials and forces involved.

Polyvinyl chloride (PVC) is commonly used for manufacturing Kompressorpipes, Waterpipes, and Filters.

The metric square thread is characterized as having a square-shaped profile that provides efficient transmission of force and minimizes wear.

Multiple square threads are used when groot sterkte benodig word.

A Joule is defined as the work done when a force of 1 N acts over a distance of 1 m in the direction of the force.

The symbol shown in FIGURE 4.14 represents a Verstelbare vloeistofbeheer klep.
