Điều gì khiến cho chiếc xe của bạn bị rung lắc? Có thể đang có nhiều vấn đề và nguyên nhân gây ra. Nguyên nhân về kỹ thuật xe là điều phải đặc biệt chú ý.
Sử dụng một chiếc ô tô lâu dài, chắc chắn điều không tránh khỏi là các vấn đề kỹ thuật của xe ngày càng đi xuống. Một trong những vấn đề xảy ra là sự rung lắc xe khi chuyển động. Điều này làm bạn khó chịu khi ngồi trên xe. Hơn thế nữa, nó còn ảnh hưởng đến các tính năng an toàn, dẫn hướng trên xe. Vậy nguyên nhân nào dẫn đến sự rung lắc n
HVAC industry offers good potential for numerous careers in various fields as in Design & Drafting, Execution & Maintenance, AC Technicians and sales & Marketing. Apart, it also provides scope even for self employment and entrepreneurship. HVAC industry can even thrive in times of poor economy. According to US Bureau of Labor Statistics, a typical Technician can earn around US $18 dollars per Hour, narrating the work and economical potential of the industry.
If any one want to k
I'm glad to inform you that IMF'18 is live now and you can register your participation online. As the event is quickly approaching and your early responses would be exciting.
Likewise, we are putting our best efforts to make your participation in IMF more worthful.
We sincerely hope you will carry back pleasing memories that you can share to inspire your friends and peers. The excitement is growing every week and will feature 5 thematic plenary workshops with more than 50 e
I got my first 3D printed aluminium alloy parts. As the image shows it looks like it’s been manufactured using casting. The 3D printing technology used to print these parts is called Direct Metal Laser Sintering (DMLS). It’s one of many 3D printing technologies available these days

Manufacturing processes have come a long way since the industrial revolution and with the introduction of new technologies such as additive manufacturing, it will only get better and more advance. But as Mechanical and manufacturing engineers ( and Product designers) how well do we know various manufacturing processes available. Are we slowly losing some of the oldest manufacturing techniques.
Test your manufacturing process knowledge here and see how well you understand the different pro

Voxel8 was founded in 2014 by scientists and engineers from Harvard University. This company was supported by Braemar Energy Ventures and ARCH Venture Partners. This company aims at developing digital footwear manufacturing systems which revolutionalize how footwear products are designed, manufactured and sold to the customers. In July, the company raised funding of $12 million to which Autodesk also contributed.It has also been named as one of the MIT Technology Reviews of 50 smartest companies
A brake which uses air as a working fluid is known as pneumatic brake. The system actuated to apply this phenomenon is know as pneumatic brake system.
An pneumatic brake system or a compressed air brake system is a type of friction brake for vehicles in which compressed air pressing on a piston is used to apply the pressure to the brake pad needed to stop the vehicle.
Construction of pneumatic braking system
The simplest air brake system consists of

Mouse Trap / Pendulum Dynamics Challenge - Part I
Mice are a problem all over the world, and as a result, I'm sure that there are mouse traps of various sorts found everywhere. It would be utterly amazing if this were not true! In the USA, there is a very common type of mouse trap that I have seen used all my life, the sort of system

Four-Bar / Toggle Linkage Mechanism
I believe that it would be correct to say that all of the single degree of freedom mechanisms that I have discussed on ME Forums have involved only a single loop. This might lead a reader to conclude that a single degree of freedom implies only a single loop, and vice versa, that a single loop imp

Over at the Kinematics of Machines club, I recently ask if anyone could show me an example of a four-bar linkage that would be classed as a triple rocker. In the terminology of four-bar linkages, a link is classed as either a crank or a rocker:
Crank - can rotate in a complete circle
Rocker - cannot rotate in a complete circle]
Thus my question was for an example
An engine or motor is a machine,designed to convert one form of energy into mechanical energy.Heat engine burn a fuel to create heat, which is then used to create a force. Electric motors convert electrical energy into mechanical motion; pneumatic motors use compressed air and clockwise motors in wind up toys use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create forces and eventually motion.
Agriculture is the backbone of the strong economy. Agriculture is demographically the broadest sector and plays an important role in the overall economic development in India since India ranks second worldwide in farm outputs. So, this is another Mechanical Startup Story from the Agriculture based start-up Sickle Innovations.
Sickle Innovations started in 2014 by the encouragement of Centre for Product Design and Manufacturing and Indian Institute of Science Bangalore. Since in Indian demog
