The Difference Between The Tensile Trabuco And The Hybrid Trabuco

The Trabuco was a war weapon that was commonly used in the medieval period. It was some sort of catapult that was used to throw projectiles over walls to cause damage or to injure people. The first recorded use of the Trabuco was in China, but it eventually made its way to Europe, America and several other places around the world.

Trabucos were popular because of their simple mechanism of operation and also because they could be used to fling much heavier projectiles than other similar weapons at the time. It was also easy to manufacture and maintain.While the Trabuco was considered among the most efficient weapons at the time, a lot of energy was lost in form of sound and heat.

The Tensile Trabuco

The first type of Trabuco to be used was the tensile Trabuco. This type of Trabuco required many people to operate. One of the largest Trabucos ever made needed about 250 people to operate. This made it difficult to operate because coordinating such a big team of people was not easy. It could make about four shots in one minute and this was quite impressive at the time.

The Hybrid Trabuco

To overcome some of the limitations of the tensile Trabuco, the Arabs in the Middle East came up with the hybrid Trabuco. This type of Trabuco had extra weight on one of the ends of the arm of the weapon. This enabled it to fling projectiles that were much heavier to even greater distances. It also required less people to operate. Europeans on were impressed with this new design and started making them as well. They kept making improvements to it to make it more efficient. With the introduction of gun powder, Trabucos started becoming less popular, and that is how they stopped being used as a weapon of war.


The Trabuco is a very important part of war history according to Today, much smaller versions of the weapon are used in schools to demonstrate some concepts in physics. They are also found in various museum around the world. There are videos online that show how to make a simple Trabuco at home.

Michael Lacey-The mathematical mastermind

On 26th September 1959, a mathematical intellect Michael was born. Michael is an outstanding American Mathematician; he received his B.S in 1981 from the University of Texas, Austin. Later on, he received his Ph.D. in 1987 from the University of Illinois, Urbana-Champaign.

His career and achievements.

In 1987, he started his career journey and worked as an assistant professor at Louisiana State University, Baton Rouge. In 1988 he worked as the Assistant Professor, University of North Carolina, Chapel Hill.

In 1989 Michael Lacey was the Assistant Professor, Indiana University, Bloomington, in 1996 Michael worked with Christoph Thiele, the two examined bilinear Hilbert transformation and managed to solve the transformation in 1996. This achievement won them an award the Salem Prize. In 1998 he became the Associate Professor, Georgia Institute of Technology, Atlanta, and in 2001 Full Professor, Georgia Institute of Technology.

Due to his exceptional work and commitment Michael Lacey has received several grants, in 2015 he received an Australian Research Council grant, in 2012 he received an NSF individual grant worth $312 000.

More awards that Michael has received are; in 2004 he received the Guggenheim Fellow award, in 2008 Fulbright Fellowship, Buenos Aires, Argentina.

Four years later in 2012, he received the Georgia Tech Mentoring Award, the most recent award was in 2013, where he was honored and made a member of the American Mathematical Society.

His works

Michael Lacey has made considerable steps in his career and has published over 100 research papers. He is a mentor to many undergraduate students, and his work has continued to assist other students globally.

Michael also takes up short-term positions in other universities like the University of Minnesota where he mentors more students as well as sharpen his skills.

Michael has also worked as an editor of the Journal of Geometric Analysis and is a teacher ready to propel mathematics to another level and ensure more students enjoy and understand the subject.
