1.2- What is the single most signifcant contribution o engineers have made or

the betterment o mankind?

I believe the most signifcant contribution o engineers is generating

electricity. Electrifcation o homes, cities, arms has changed the lives o

humankind. Engineers have made electricity to happen starting rom its initial stage

to be generated rom uels like oil and gases hydrocarbons, hydroelectricity which

uses water alls as a source o generating electricity and later wind and geothermal

sources o electricity were also innovated or the betterment o green electrifcation,

generally majority o the development in technology uses electricity as a source o

power to perorm their tasks.

1.5- List most signifcant scientifc or engineering achievements since 1300?

he most signifcant inventions in general

2000’s- *acuum cleaning robot, +ow cost laptop, !pple touchscreen cellphone,

1.6- E/plain the principal reason or the meager advancement in technolog during

the middle ages?

'ollowing the all o oman Empire due to large land owners sought to protect

themselves and their properties and the increasing population in cities and largeagricultural production also orced or the innovation o labor saving machines like

wind mill and advancement o gothic architecture in urban.

3.3- "easons (h onl 13 o engineers are registered licensed Also list branches

and career (here registration is most needed

he main reason like ailure o 'E e/am, ailure o &E E/am and some

government jos may not re0uire license but the basic problem is engineering needs

high potential o math and practice during school time, successully completing the

!)E accredited engineering program doesn1t mean you can pass the 'E e/am

easily, students need careul revision and immediate action to take the 'E e/am

beore or ater the graduation. !nother issue is fnding an internship since &E

license e/am re0uires actual our to fve years o e/perience according the

licensures state, generally the basic reasons are the knowledge o the student

ac0uired during school time to pass 'E e/am easily, the interest o the student to

immediately take action or the e/am and participate in EI, and the rules o states

in providing license to engineers.

)ranches o Engineering where license is needed include "ivil Engineering,

Electrical Engineering, (echanical Engineering are the widely known or 'E e/am

due to the job re0uirement needed , and "hemical Engineering, )iomedical

Engineering and other speciali2ations which speciali2e in a very sensitive

engineering proession also need license studies like %otware engineering may not

re0uire license due to the incompetence o the student3 employee doesn1t a4ect the

environment or doesn1t have direct impact on mankind directly in long run but

sensitive proessions like "ivil Electrical and mechanical Engineering need license



due to the long run impact o improper implementation can yield destruction in

human lie and property.

3.1- !ra( +amil tree diagram sho(ing evolution o engineering proession and

engineering specialities including appro/imate dates?
