Answer to Question #193071 in Mechanical Engineering for Emily

Question

People living nearby have specific concerns about two operations carried out at the factory:

■ Stamping, which is a noisy process

■ Plating, which uses cyanide and is therefore perceived as a deadly process by some residents. 

The company has decided to make a presentation to the local residents association explaining how it complies with legislation and demonstrating its good ‘green credentials’, particularly in respect of discharging waste water from the onsite treatment plant into a nearby culvert which runs down to a river. 

Make a list of generic constraints that impact on engineering businesses.

With respect to the two main concerns of residents (Stamping and Plating), identify the key pieces of legislation which could apply here.

Answer 1

Generic constraints that Impact on Engineering business include;

1) Availability of materials.

2) Cost of materials.

3) Environment constraints.

4) Time

5) Quality to be maintained.

6) Labour constraints.

Stamping: Stamping leads to large production of noise.

The legislation included here will be a noise limit as prescribed by local authorities.

To reduce noise, a noise Barrier should be used along with thick vegetation so that noise can be constrained.

Plating: Cyanide used in plating is dangerous to the human being when consumed.

- Legislation here includes a limit on effluent that will come from the factory in the form of a concentration of cyanide per liter of effluent.

A proper treatment plant should be set, so that cyanide amount can be reduced to a limit before discharging to nearby river or land.
