(a) For each of specimens H (SPADE), l (SECATEURS) and J (OPEN ENDED SPANNER) name two farm tools that can perform functions similar to those of the specimens.
(b) Describe how each of specimens I and J is used.
(c) Describe each of specimens H and J.
(d) Enumerate four advantages of using farm tools for farm work.
Explanation
(a) Tools that can perform similar functions as; specimens H, l, and J
- Specimen H (Spade) - Hoe, shovel, and hand trowel
- Specimen I (Secateurs) - Saw, sickle, cutlass, and shears
- Specimen J (Open ended spanner)-Wrench, ring spanner and pliers.
(b) Description of how specimen I (Secateurs) is used -
- Open the handle to widen the blades.
- Fix the opened blades against the material to be cut.
- Release the handle
- Press back the handles to close the blades and cut the materials.
Description of how specimen J (Open-ended spanner) is used
- Fix the opened end directly on top of the bolt (appropriate size).
- Turn the handle clockwise (to tighten) or anti-clockwise (to loosen) the bolt.
- continue tó turn until the bolt is firmly fixed or loosened before releasing the handle.
(c) Description of each of specimens H and J Specimen H (Spade)
- Has a long wooden/metallic handle.
- Blade is metalic (steel)
- Blade is rectangular, flat and sharp at one end for each penetration into the soil.
- Handle widens at the posterior end to form a triangular block or "D" shape for firm handling.
Specimen J (Open-ended spanner)
- It is metallic.
- Both sides end in a hexagonal shape of various sizes that fit the heads of bolts.
- Flattened metallic handle.
(d) Advantages of using farm tools for farm work
- Minimize injury to the farmer.
- Make work easier/minimize drudgery.
- Enhance faster completion of operation/saves time.
- Increase farmers' productivity.
- Enhance certain operations, e.g. budding.
- Not expensive to acquire.
- They are sometimes the only way to get certain operations done on the farm.
- Easy to operate and requires no high technical know-how.
- Can be operated at all times.
- Easy to maintain.
- Do not require any specialized sources of power to operate.
