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

LightSail Energy is one of the most eminent startups that hails from Silicon Valley founded by Danielle Fong, Steve Crane, and Ed Berlin in 2009. LightSail Energy has the concept of low-cost grid-scale energy storage solution in order to optimise power grids, democratizing access to energy and adhere on sustainable development. Investors such as Khosla Ventures, Innovacorp, Triple Point Capital, Peter Thiel, Bill Gates have invested in LightSail Energy.
LightSail Energy produces one of the
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
Holla People!!!! Since it has been a long time I was waiting for starting the blog on Mechanical Startups, my first entry to the new blog starts with the few hardware startups in India. ATHER ENERGY is a privately owned founded by Swapnil Jain and Tarun Mehta in 2013 headquartered in Bangalore Karnataka.
This budding startup has received fundings from Hero Motocorp, Tiger Global & Flipkart. Profoundly being a part of Automotive industry and producing electric vehicles, in the in-house

What do you know about hysteresis? Many Mechanical Engineers will associate this term with the magnetization curve of a piece of magnetic material, and quickly conclude, "I don't have to worry about that!" But that would be wrong. While hysteresis does occur in magnetic systems, it happens in many other situatio

Two Short Math Problems
Do you ever read the ads that appear on ME Forum? I try to avoid them as much as possible, but an organization called BRILLIANT has put up some interesting math problems of late that have caught my eye. Two of them are the subject of today's post.
The first problem that I want to discuss is actually more recent than the other, but it gives us a good plac

Comments on a Textbook Theory of Machines
R.S. Khurmi & J.K. Gupta
Recently, through the wonders of the Internet, I have come across a copy of the textbook Theory of Machines by R.S. Khurmi and J.K. Gupta (S.Chand & Co., Ltd., 2005). Since theory of machines has been my primary technical interest since the early 1980s, I was interested
