Bicycle

A mechanism I find useful is the bicycle. It helps us move from one place to another fast and easily with minimal costs. In addition it makes a good exercise while traveling short distances without poluting the enviroment. It works by applying force on the petals and doing a rotary motion witch transfers motion energy to the wheels through a chain. The spin of the wheels prevents the bicycle from falling when it's moving. 

Cam and follower mechanisms
A cam and follower is formed by the direct contact of two specially shaped links. The driving link is called the cam  and the link that is driven through the direct contact of their surfaces is called the follower. The shape of the contacting surfaces of the camm and follower determines the movement of the mechanism. In general a cam follower mechanism's energy is transferred from cam to follower. The cam shaft is rotated and, according to the cam profile, the follower moves up and down.  The main benefit of this type of cam follower mechanism is that the follower moves a little bit and helps to rotate the cam 6 times more circumference length with 70% force!!!

                                                               

Mechanisms

Choose a mechanism that you like and you find useful and describe it. Explain how it works, which type of motion is involved, and refer to its uses.You may illustrate your paragraph with an image of the mechanism.

I study 6 courses per week in this semester. I study maths, which is 4.30 hours course, physics, 3 hours course, programming which is a 3 hours course and 1.30 of practical exercise. I also study science of materials that lasts 4.30 hours in a week, mechanical designing which is separated in two, 3 hours course, of both theory and practical exercise and of course  English for mechanical engeeneering, a 3 hours course.My favorite course is mechanical design because i like creating new ideas and support new plans of design.By the looks of it someone might just say that this is an exhausting routine because every class starts at 9 o' clock and the last finishes at 5 o' clock every day (except weekends). this makes classes feel more difficult and in some cases you feel so bored that you find it hard concentrate and the only thing that sticks in your mind is when are you going home and lay on the bed :)

Timetable

This semester I have a difficult timetable. Most of the time i start lessons at 9.00mm until 17.00pm. I do 6 lessons and that is the reason for the difficult timetable I have. The 6 lessons that I have is Maths,Physics,English for academical purposes,Autocad,science of materials and programming. The lesson that I like is Physics because the teacher leave us early. 

my timetable

This semester i have six subjects to complete until the end of it.Every class last for one hour and a half.I usually have a break after a class for about thirty minutes but there are some times that i have more time like one or two hours.My timetable includes physics,science of materials, English for academic purposes and design in computers(auto-cad).i have a total 20 hours classes every week.

Timetable

  This semester I have a busy timetable, with 24, 1 and a half hour courses every week. Usually the courses start at 9am and end at arround 5pm in the afternoon. The courses that I have are Maths, Physics, Material science, english, design and programming. Of all the days of the week monday is the busiest, I have 4 courses witch take 7 and a half hours with only half hour breaks in between.
