Engineering and design Definition and 20 Threads

I am currently building a dynamometer to measure the power consumption and rpm of a mars prototype. The plan is to place each wheel of the rover onto a pair of rollers but I am currently struggling with determining the optimal roller separation. If they're too far apart, the wheel might not...

Hi, making the thread again since I posted a pic with a link, so I apologize. What particular mechanic or engineer can design/create (using a CAD, new software, etc), a hydraulic car lift to mechanically lift a car? Plus its accessories/machinery/cables in a regular auto repair shop, for the...

I'm working for a project with a goal of analyzing data obtained from a device that extract data from bodies of water, such as bacterias found, the chemical levels, etc. I've been instructed to use existing equipment for it to work. What I've been recommended to use include: bateries, solar...

My name is Joe, I'm 36 years old and currently between work. I live in The city of Erie, Pennsylvania. My interests are in the phields of electricity, physics, chemistry, and all engineering principles related. As I am only a high school graduate with no formal training, my education is self...

Hi Everyone, I could use some help in SolidWorks, when I go to sketch geometry, the software creates a lot of lines that extend off the starting point and they don't go away until I snap back to the starting point. I have an image attached to show what is happening. This creates a problem...

Hi All, I must calculate the torque and for an agitator motor. An anchor type agitator/scraper, removing crust off the edge of a tank. My instinct is the max or startup torque will be = (Moment of Inertia) x (Angular Acceleration) + (Drag force of the submerged impeller)* Max radius +...

Hello there, I am wondering, if I were to build an elevator in a building, is it possible if I build the elevator frame (and rails) without using the rail bracket? The weight of the cart plus the contents would be supported by only 4 steel columns fixed to the ground. I know it is a silly...

Hello, I am a Mechanical Engineer a little out of practice on Heat transfer. I am trying to solve this problem. It must be solvable but i have yet to find right equations online. I have a multi Layer Cylinder made up of C350 marraging Steel,Zinc Alloy-12 , then 6061 Aluminum T6. All that is...

Hi all, I just want to gain some perspective as I am sure there are people in the same boat or have been where I am. I am in the home stretch of my Ph.D in Biomedical Engineering, I have manuscript published and a couple more in the pipeline. I work in big data and how to use it to come up...

Designing a machine. For it to work properly there would need to be a mechanism that connects the linear actuator to the stand that would allow for the actuator to move horizontally relatively freely with applied forces at the bottom, when there is simultaneously a downward applied force by the...

How to calculate the force or pressure by the movement of the abdomen (due to inhalation and exhalation) on the vest(tight T-shirt for example) that we are wearing ?

Greetings, The application is a wiped film evaporator (~1.2-1.5 kg/hr throughput). The concentrate and the distillate gravity feed round bottom flasks. I'm not worried about the cold-trap waste. The evaporator volume is under vacuum (~0.003Torr). I want to pump the liquid from the...

For a business project, I'm looking into the viability of a greenhouse situated in Canada's far northern town of Iqaluit. The problem is how to mathematically simulate the internal air temperature of the greenhouse. What I already have are detailed 3D renderings of the greenhouse as well as all...

Hello all, I am trying to remember (I did it in Uni) how to calculate the effective mean radius of an annulus that contains a pattern of holes on a PCD. Consider the following image (pinched from: https://www.solenoid-valves.com/ ): If one was to vary the value of PCD, then the effective...

We typically solve idealized problems in physics coursework. How about when we deal with real world Photonics Industry Problems, what Physics equations we will be talking of here?

First, thank you for taking the time to read this. I need some guidance as I am inventing somewhat of a new edible product. Curious as to if someone can point me in the right direction for the type of chemist I should actually be looking for. At first I was under the impression that it would be...

Hi There, Newbie to the forum, I work as a design engineer for a company called Helical Technology. Studied Engineering with honours in Motorsports at uni, recent graduate :) looks like an interesting forum! hopefully I can help with some queries as I hope you guys can help me with mine! thanks!

Hi i want to know how to make a 3D metal box whose length, width, and height i can change. For example, i have a box of 3 m x 3 m x 3 m. i should be able to extend any dimension by a maximum of 1 meter i.e 4 meter (say). I want to use this to store items whose size is unknown, but the limits of...

I'm a student from Newcastle University from Singapore Institute of Technology (A new launched University in Singapore) and am majoring in Electrical Power Engineering. My current final year project requires me to research on BS1363 and try to reduce the amount of copper usage as we know that...

Homework Statement There is an air-tight 1L Canister filled with 90% water and 10% N2O. This canister is attached to some clear tubing which is not entirely air-tight. At the end of this tubing are some tungsten particles averaging ~1µm in diameter with total mass of 60mg. The contraption is...
