What position did BJ Habibie hold in 1978 and what roles did he do on those positions?
And in 1978, he made a step into government as minister of research and technology. This was the beginning of more than 20 years continuous service as a member of the Indonesian cabinet. Simultaneously, he headed 10 state-owned industries, including arms and energy.
What is Habibie Factor?
This means using heavier materials for the aircrafts body, using aluminium and steel alloys. After crack points can be determined, the SF could be decreased and aircrafts can use lighter material. This is what’s called the Habibie Factor, which can reduce the plane’s operating empty weight by 10\%.

How long did Habibie work as technology director in Hamburg and Munich?
Later, he became the Vice President and Technology Director of MBB Gmbh, Hamburg and Munchen (1973-1978), and Technology Senior Advisor to the MBB Board of Directors (1978).
Who found crack theory?
Fracture mechanics was developed during World War I by English aeronautical engineer A. A. Griffith – thus the term Griffith crack – to explain the failure of brittle materials.
What is the crack theory?
The Griffith theory states that a crack will propagate when the reduction in potential energy that occurs due to crack growth is greater than or equal to the increase in surface energy due to the creation of new free surfaces. This theory is applicable to elastic materials that fracture in a brittle fashion.
What is BJ Habibie known for?

Habibie, in full Bacharuddin Jusuf Habibie, (born June 25, 1936, Parepare, Indonesia—died September 11, 2019, Jakarta), Indonesian aircraft engineer and politician who was president of Indonesia (1998–99) and a leader in the country’s technological and economic development in the late 20th and early 21st centuries …

Why did school make him bored Quizizz?
School made him bored because it required endless memorizing and reciting. He often skipped classes to study on his own or to play his violin. Einstein made many theories on Physics, but the most famous theory is about atomic energy. Einstein’s theories made him famous, even though few people understood them.
What is biography text Quizizz?
a text which presents information about something, as it is. a text that describe a particular person, thing, or place in specific.
When a crack will propagate?
From the energy criterion theory, the crack will propagate when the energy needed for a crack to propagate is sufficient to overcome the resistance of the material. The energy release rate, G, is the change in potential energy with crack surface area for a linear elastic material, (3.13)
Do cracks propagate in tension or compression?
When the tension exceeds the strength of the crack tips, the crack will grow. In laboratory conditions, the largest cracks will be be perpendicular to the applied tension. After van der Pluijm & Marshall (1997). Tension cracks can also be produced by compressive stress.
