Describe the parts and uses of a G-clamp. Compare resistant, modern, and smart materials. Discuss smart/modern materials versus compliant materials and the uses of structures in construction.

5. a. i. A freehand pictorial sketch of a G-Clamp is required. It consists of a C-shaped frame, a screw mechanism, and a swiveling pad. ii. The tommy bar is the handle used to turn the screw, and the frame is the main C-shaped body of the clamp. iii. One use of a G-Clamp is to hold workpieces securely to a workbench during tasks like drilling or gluing.

b. Table 2:

S/N	Type of material	One example each	One property each
1	resistant material	Steel	High strength
2	modern material	Carbon fiber	High strength-to-weight ratio
3	smart material	Shape memory alloy	Changes shape with temperature

6. a. Table 3: | S/N | Smart/Modern Materials | Compliant material | | :-- | :--------------------- | :----------------- | | 1 | Has change in shape | Is flexible | | 2 | Its colour changes with stimuli | Its colour is permanent | | 3 | Can reflect with light | Is dull | | 4 | Can change transparency | It is opaque | | 5 | Can produce different colours same time | Has a fixed colour | | 6 | Is elastic | It cannot be stretched |

b. i. Two uses of structures in construction:

• Provide shelter for people and activities.
• Support loads such as roofs, floors, and equipment. ii. Two natural structures:
• Tree
• Spider web iii. Two factors to consider when running and managing a small-scale enterprise:
• Financial management (e.g., budgeting, cash flow).
• Marketing and sales strategies.

c. Two tools for gathering data to design and make a kitchen stool:

• Surveys/Questionnaires (to gather user preferences and ergonomic requirements).
• Research (to study existing stool designs, materials, and construction techniques).
