    Gender Based Hiring Quotas in Australia

    Are you suggesting that group-think is gender-specific? That idea would align with the definition of sexism quite well. "Formal education is a weapon, whose effect depends on who holds it in his hands and at whom it is aimed." ~ Joseph Stalin

    Gender Based Hiring Quotas in Australia

    1- Fix what? 2- What attitudes? 3- What exactly is the problem? 4- I know exactly how to fix it. Hire the most qualified applicants based purely on a candidate's merit as it relates to the job position. Do not make policies that turn a position-filling process into a...

    Why do modern small petrol generators (~1kW) have such mediocre specs?

    What do you mean by "5 hours endurance"? "Formal education is a weapon, whose effect depends on who holds it in his hands and at whom it is aimed." ~ Joseph Stalin

    Why do modern small petrol generators (~1kW) have such mediocre specs?

    The engine in a car is less influential to the overall cost to produce the unit than the engine is on a generator. They have less demanding packaging constraints. They can sacrifice a cylinder to gain room. The engine has a lower duty cycle. The engine in a fiesta is not designed primarily...

    Why do modern small petrol generators (~1kW) have such mediocre specs?

    If you can find a supply of free catalytic converters and turbochargers and EFI systems that will work with those small engines and their packaging demands, you would have a point. By the way, the emissions point is not moot. They have to pass emissions standards that are set for that type of...

    diesel exhaust heat recovery

    If the intake air temp is hotter, then less heat from the cylinder and combustion chamber will be transferred into the intake charge prior to ignition. The combustion chamber would probably maintain hotter temperatures, but the cooling system might compensate for it to keep the coolant temp at...

    First Entry Level Job

    Don't job hop through a small business like that. They have enough to deal with aside from putting training resources into you only to have you walk out of the job the day you might actually become a productive member of their team. 1 year? You're barely out of training at that point. You...

    Why do modern small petrol generators (~1kW) have such mediocre specs?

    Those generator engines are governed to a maximum of 3600 RPMs. Do you know how horsepower is calculated? They don't turbocharge them because they are carbureted, have to meet emissions standards, be reliable, and they are air cooled. Why are cars so backward in terms of technology? I have a...

    How frequent is it for someone to leave the engineering profession

    People with engineering degrees leave the field, but engineers can't leave the field. Those are not mutually inclusive characteristics, either. Wherever engineers go, they will engineer the things. "Formal education is a weapon, whose effect depends on who holds it in his hands and at whom...

    How does one accurately measure the effective dynamic load of equipment trasmitted to the floor?

    I'm not sure how this machine is mounted to the floor, but maybe my idea can help or lead you to something that can help. Strain gauge rosette on a structural component of the machine that is coupled post-dampening to the floor. Digitally record the gauge's voltage readings with whatever daq...

    A coming engineering shortage ? ---- Who agrees ?

    Will it be a shortage of engineers? Or will it be a shortage of talent? Companies sometimes will assign a young engineer primarily with repetitive and dull responsibilities that don't grow their skillset. Once you kill a guy's enthusiasm, it won't come back as strongly ever again. Throw...

    2 Stroke Reverse Uni-Flow Cam Engine

    Harley Davidson single cylinder engines used that concept on their intake valves until about 1912. Apparently it worked back then, but it didn't work well on their V Twin engines. I wish I had more information than that, but its proprietary information from the early 1900s. I know some guys...

    Mechanical Rotating Equipment engineer looking to change to Automation

    That varies from company to company and depends on what kind of systems they are using. My company has in-house PLC guys. My brother is an automation technician at a small company where he started working in high school as an "intern". I gave him some pointers and he took it upon himself to go...

    2 Stroke Reverse Uni-Flow Cam Engine

    I think the biggest practical improvements will be gains in the ability to keep an engine running near peak efficiency under a wider variety of load/speed conditions. New methods or systems added onto engines to re-harvest waste heat and pumping losses will probably also get attention in...

    2 Stroke Reverse Uni-Flow Cam Engine

    I can tell you that everything I underlined is completely false and it makes me question whether or not you have worked for a manufacturer. Selling an engine that is demonstrably more durable and demonstrably more fuel efficient would be the most profitable thing that an engine or auto...

    Engine Reliability Data

    I'd consider it important to distinguish between durability and reliability in a few cases. Reliability, to me, is measurable by the likelihood that an engine will operate over a given period of time without failing in any way that takes it out of service for any measurable length of time. I...

    Engine Reliability Data

    I bet they showed up, but could they fix the issue on budget on time? Usually I see the issues like that one being ignored willfully, then downplayed by people trying to protect their own ass, then their boss downplays his inaccurately low estimate of how big of an issue it is, then they launch...

    Engine Reliability Data

    I think consumer reports generally does a good job. There are some anomalies in their rankings, but for the most part it jives with what I've observed. "Formal education is a weapon, whose effect depends on who holds it in his hands and at whom it is aimed." ~ Joseph Stalin

    Engine Reliability Data

    Does anybody know of a way for a consumer to gauge the endurance life of an engine before purchasing a vehicle equipped with it? My dream is to go to a vehicle dealership and be presented with data from unbiased endurance tests on an array of vehicles and their components. I want to know how...

    Home Built Racing Engine

    The R1 transmission and clutch would be over built for the destroked engine's power. What would the operating range be for engine speed? That engine would make its peak torque at a very high RPM, most likely. The intake velocities would be low with the new rod:stroke ratio will cause the...
