QUESTION

PART A $(15\%)$

As the company Plants and Operation Manager, you have been requested by your company director to provide a report that describes $($C$1)$ your process of choosing construction equipment for your current job. In the report, you must explain $($C$3)$ with in$-$depth knowledge $($WP$1)$ the wide range of conflicting requirements $($WP$2)$ regarding the specifications of each machine that has to be checked and fulfilled, in designing the system of the most compatible loader$-$hauler combination. The target is to select the most productive selection in terms of time and cost, based on the best engineering practice $($WK$6)$ that requires abstract thinking $($WP$3).$ Find a feasible selection of loader$-$hauler, or excavator$-$hauler or scraper alone, for an earthmoving operation to move approximately $35,000$ bank cubic meters of sandy clay to be dumped about $1\mathrm{.}5$ km away.

PART B $(15\%)$

After comparing $($C$2)$ a wide$-$range $($WP$2)$ of possible plants combination for the given function and operation, and using the designed selection system $($WK$5)$ based on best engineering practices $($WK$6)$ that require abstract thinking $($WP$3)$ in PART A$,$ analyse $($C$4)$ the total resistance of the plant movement using in$-$depth knowledge on interdependency, to develop the Total Resistance graph for the hauler when:

a$)$hauling fully loaded

b$)$return empty

The format of the graph is as shown below in Figure $1.$Figure $1$
