Typically the value engineering (VA/VE) practices take already designed, validated and productionised components and apply the VA/VE methodologies to increase the value of the product either by reducing cost (weight) or increasing functionality.

When deciding for the beam section to have, the first consideration to be done is what purpose it need to serve i.e. what kind of loads it will deal with. In general the following cross section choices are available for … Read the rest

Suppose your motor vehicles speedometer not working and you need to know your vehicle speed for the given engine speed for a certain gear ratio. How you can do that , let’s see..

Say, Engine rpm= 3000

Gear ratio=1.5

Properly designed bolted joint is extremely important for striking the balance between the cost and life of the joint.

As a design engineer, for a good bolted joint design, for a given loading conditions and materials of the abutments, you … Read the rest

If you are wondering what is stack-up analysis/calculation, the answer is determining worst case scenario. Moreover, the problem can sorted out in early stages of design rather than undergoing prototyping and finding out the issue.

We have already discussed how … Read the rest

What is **DFMEA**?

DFMEA is **D**esign **F**ailure **M**ode & **E**ffect **A**nalysis. It is the application of FMEA to a specific product/system in a disciplined manner that anticipates failures to prevent their occurrence in design.… Read the rest

**What is hydraulic cylinder?**

The hydraulic cylinder is a device that converts the energy of fluid into mechanical energy. The fluid is pumped into the cylinder by means of a pump and it can be used to move a load. … Read the rest
