    What can be done to make electric motors louder?

    You can add a sensor for voltage or current that will tell you when you are sending more power to the transmission. Then amplify that signal using an electronic amplifier and send it to a speaker or other noise making device.

    Is My Flow Laminar or Turbulent at Re= 200,000?

    Sometimes when you are working with cars, although the flow might be theoretically laminar, we have to account for the vibrations that will most likely make it turbulent. You can still use the Reynolds number you obtained but with the turbulent equation.

    Sensor in car to calculate weight distribution?

    Lsos first of all thanks for your input. The results don’t have to be extremely accurate. Remember that we are going to use them to drive a dynamic spoiler that can only move within a certain range. What we are trying to do is use the three parameters described before (velocity, braking...

    Sensor in car to calculate weight distribution?

    Ranger Mike and Kozy. Thank you for your answers. I was thinking that installing a 6 axis accelerometer in the center of mass of the car might not give accurate results. The other option was to install three sensors that would give me the velocity, steering and braking force: -Velocity...

    Sensor in car to calculate weight distribution?

    Hello, I’m currently working on a project in which I need to know the weight distribution in the four tires of a car at all times. I was thinking to install strain gauges somewhere in the chassis, or displacement sensors by the suspension. However I don’t feel these methods will give me...

    Which wheel loses traction first?

    Hello and thanks for your fast answer. The car we are using has a limited slip differential. More specifically a Torsen LSD. I will read that post and come back as soon as I can. What we are trying to do is a "2 wing dynaimc spoiler" that will raise its left or right half to provide the...

    Which wheel loses traction first?

    When you drive a real wheel drive too fast around a corner, the two inner wheels lose some down-force due to mass transfer. If you oversteer, does the rear inner wheel lose traction first? And then trigger the oversteer? If so, are there any equations to determine how the weight is...

    Linear actuators for mechanical project

    Hey guys, I was wondering if you could help me out here. I'm working on a project that needs two fast linear actuators which I'm planning to control with the Arduino logic board, but I can't seem to find anything that suits what I need. Here are the specs. -Type of actuator: Linear...

    Loaded beam in compression? (buckles?)

    Hey guys, I know this is a simple question but I'm not really sure how to do it. Let's say we have a beam supported by two pins at both extremes. There is a central load on the beam, so it will deflect in the direction of the load. But we also have an axial force compressing the beam. My...

    Solving a Mechanical Engineering Problem: AISI 1020 HR Steel Shaft

    Hey. This is my first post, I'm a Senior in Mechanical Engineering, I will help others as far as I can. I'm trying to solve the problem from the picture. The shaft is loaded with 2 transverse loads, 2 moments and 2 torques. The critical point is immediately to the left of "B". The material is...
