Degree: Aerospace Engineering (Masters) - Manchester University
Who am I?
Hi, my name is Marc and I am in the 2nd year of my research PhD at the University of Manchester linked with Airbus.
Why do I do this?
My reason for becoming a tutor here is that I hope to one day become a research lecturer. Yet I believe that by helping those earlier in their academic life I can ensure they have the foundations to understand future more difficult subjects.
Where's my experience?
I have held tutorials for degree level modules but have also helped teach my younger siblings during their GCSE's and A-levels. Sometimes helping them learn subjects I was never even taught!
How do I teach?
As I am an engineer at heart I like to apply everything I teach to real life situations. I find it makes what you are learning far more real and therefore understandable. I personally have always found that by understanding why something happens and how it occurs in real life is the key to remembering what you have learnt. It gives you a visual thought to recall and take knowledge from rather than trying to memorize lots of equations (which believe me is hard work and time consuming).
Why choose me?
Are you looking for a tutor who scored consistently high through his academic life, not through natural talent but through hard work and determination?
Are you looking for a tutor who has knowledge way beyond the necessary requirements of GCSE and A-level?
Are you looking for a tutor who wants to make learning real and fun and something you remember not just forget the following day?
If you answered yes to any of those questions its very likely I am the right tutor for you.
Hope to hear from you soon,

Pressure is the force exerted by one object on another object over a given area of contact.
The following equation can help understand and also explain how pressure works:
pressure = force / area
p = f / a
If you imagine 'f' as being above 'a' in the equation then it should help you remember that Pressure is the Force OVER the Area given.
an example of this is:
If a 5 Newton force is applied to an area of 2m2, what is the Pressure?
f = 5 Newton , a = 2m2
Therefore, p = 5 / 2 = 2.5 N/m2
You may of seen Pressure written in Pascals (Pa), this is fine as N/m2 and Pa are directly proportional.
eg. 1N/m2 = 1 Pa
It is also worth understand how changing the Force and Area affects Pressure.
To increase pressure - increase the force being applied or reduce the area the force is acting on.
E.g. When pushing a pin into a cork board you must press harder (apply more force) to make it pierce the surface. If the pin has a sharp pointed tip then the area that is touching the cork is small meaning pressure at that point is very large.
To decrease pressure - decrease the force being applied or increase the area that the force is being applied too.
E.g. if your were to lightly press the pin into the cork board it would likely not pierce the surface and pin into the board. The reason for this is there is not enough force being applied by your hand to push the pin into the cork. Also if the tip of the pin was blunt and rounded rather than sharp and pointed the increase in area means the force you are applying is spread over a greater area. Therefore the pressure being exerted by the pin is smaller.
Pressure = Force / Area
p= f / a
1N/m2 is the same as 1 Pa
Increase pressure - increase the force or reduce the area.
Decrease pressure - decrease the force or increase the area.see more
