Q.12-2008

• A new harbour is to be built at a new location. The suggested new location is either at a bay or a cape. Four models for the structure of the retaining wall are given. Table 12 below shows the location and the characteristics of the four retaining walls.

• Explain the best location and the suitability of each characterictics in Table12.

• Determine the most suitable retaining wall to be used.

• Give the reason for your choice.

Worksheet

Answer Characteristic Explaination / reason

The ______ Water is calmer

______retaining wall.

Decrease the wavelength / higher water pressure at

higher depth.

______ surfaceReduce energy, wave is

reflected at different direction.

______ retaining wall

Protect form high wave / overflow of water.

No 11 – characteristics ExplainationMethod of moving lawnmover- Push the handle

- Bigger force produced

Mass of lawnmower - Big

- To increase the stability

Size of cutter blade- Big size of cutter blade

- Increase the cutting area of cutting grass

The angle between handle and the horizontal- large

- Force exerted to the ground bigger

- Therefore, I choose lawnmover M, - because it has push handle, big mass of lawnmower, big size of cutter blade

and has large angle between handle and horizontal line
