Robotic device has therapeutic potential for ankles and feet A soft, wearable device that mimics the muscles, tendons and ligaments of the lower leg could aid in the rehabilitation of patients with ankle-foot disorders.
This is the claim of Yong-Lae...
Types and working of Power Steering
There are 2 types of power steering currently in use. These are integral and linkage booster types. Both are operated by hydraulic pressure produced by an engine driven pump to assist in turning the steering mechanism. The integral power steering is...

casting (known as lost-wax casting in art) is a process...
Why Manual Transmission Cars Make a Loud Whirring Noise in Reverse?
Manual transmissions use mostly helical gears, but reverse is a special
situation that requires a different type of gear - a spur gear.
The gears that make up the forward gear ratios are all helical gears.
The teeth on helical gears are cut at an...
10 reasons why Mechanical Engineering is the best
There has always been a debate and discussion among all engineering
students about which engineering course is the best? Students always
love discussing about the best branch of engineering. Though this is a
proven fact and it needs no...
Ultrasonic Welding
Ultrasonic welding is represented as a friction
welding method, where oxides and other contaminants present on the
material surfaces are broken up and also the components to be welded are
brought together under simultaneous pressure. Molecular...
2 stroke engines in racing motorcycles
Although two stroke engines have long since been updated with four
stroke racing bike engines, two stroke engines provide a lightweight and
suitable solution for racing bikes, motocross and dirt bikes.
Earlier on, the two stroke engines in racing...
Common Rail Type Fuel Injection System
Electronic
control common rail type fuel injection system drives an integrated
fuel pump at an ultrahigh pressure to distribute fuel to each injector
per cylinder through a common rail.
This...
DISI Turbo or Direct Injection Spark Ignition Technology
DISI
includes a whole new set of innovations for gasoline engines. To
mention a few, direct injection (including cooling the air-gasoline
mixture), a new combustion chamber geometry, variable timing technology,
and nanotechnology for the catalyst....
Variable Turbochargers Geometry (VTG)
Variable geometry turbochargers (VGTs)
are a family of turbochargers, usually designed to allow the effective
aspect ratio (sometimes called A/R Ratio) of the turbo to be altered as
conditions change. This is done because...
Turbocharger
A turbocharger is actually a type of supercharger.
Originally, the turbocharger was called a "turbo super charger."
Obviously, the name was shortened out of convenience.
A turbocharger’s purpose is to compress...
Supercharger
Engines combust (burn) fuel and use the
energy of that combustion to do work. The more fuel that is combusted in
any given time then the more energy is available to carry out the
engines task. Fuel requires air (or the oxygen...
Working of Fuel Cell Car
Fuel Cell Stacks
This is the heart of the hydrogen fuel cell
car—the fuel cell stacks. Their maximum output is 86 kilowatts, or about
107 HP. Because hydrogen fuel cell stacks produce power without
combustion,...
Kinetic Energy Recovery System (KERS) in F1
The introduction of Kinetic Energy Recovery Systems
(KERS) is one of the most significant technical introductions for the
Formula One Race. Formula One have always lived with an environmentally
unfriendly image and have lost its relevance...
