# Do Value Engineering Upfront, Right at Design Stage

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.   What if we, the designers or design engineers, could do the value enhancement of the product at virtual concept design stageRead more about Do Value Engineering Upfront, Right at Design Stage[…]

# Why I-Section Beam is structurally better than same weight other sections?

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 a beam in market – Rectangular/Square Section Box/Hollow Rectangular Section Circular Section Hollow Circular SectionRead more about Why I-Section Beam is structurally better than same weight other sections?[…]

# How to calculate vehicle speed from engine RPM and vice versa

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 Axle ratio = 4 Tyre size = 12 inch radius The formula for calculating vehicle speedRead more about How to calculate vehicle speed from engine RPM and vice versa[…]

# Bolted Joint Design Calculation Example for Joint in Tension

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 have to basically select the following design parameters: Diameter or size of the bolt orRead more about Bolted Joint Design Calculation Example for Joint in Tension[…]

# Worst Case Method Assembly Tolerance Stack up Calculation for Non-Symmetric Dimensional Tolerances with Example

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 to do worst case method assembly tolerance stack up calculation for symmetric dimensional tolerances, inRead more about Worst Case Method Assembly Tolerance Stack up Calculation for Non-Symmetric Dimensional Tolerances with Example[…]
