I am planning to design an RC car to 3D print it and have some fun. It will mostly be a learning experience with the by-product of having a hopefully fun RC car by the end of it. That will probably force some decisions that might be overengineered and negatively impact performance but building...
1. Is it possible that sailing boat(going backward) turns less when rudder is full right, then rudder is at some smaller angle?
Due to too high AoA and flow separation/stall, trailing edge of rudder is sharp that also lower stall AoA...

I was wondering... Let's say we have a square platform with 4 wheels at corners placed on dirt and let's have left side wheels fixed straight and right side wheels are steerable so that when rear right goes in then front right goes out, would this way of steering work? What's your thoughts?
Good morning ,
I managed to simplify the physics of my car with only the centrifugal and traction forces. If I'm in control of it, the realism is acceptable for a city builder. On the other hand, I encounter a problem when the car follows an array of points.
The path of the car on my graph...
In a car we turn the wheels to steer. The wheels however are spinning about their axis of rotation when the car is in motion. Does the revolving motion of the wheels cause a force that opposes trying to rotate the wheels around the other axis to steer? How much opposition is created?
Here's...
Greetings to everyone,
Recently I bought sailboat with rudder which is actuated by hydraulic oil by cylnder and pump at steering wheel.

So, I'm investigating a certain way of steering a rocket in space for my first undergraduate research project. Essentially, the idea is to control the location of some mass located on a horizontal track perpendicular to a rocket, so that when the mass is moved, the center of mass of the rocket...
question: The gas pedal and the brakes of a car are used to change the velocity by accelerating the car or decelerating it. Could a steering wheel perform either of these two actions? Explain.
P.s: Of course velocity is a vector quantity and if the direction of car change there is an...
Dear All,
Hello,
I'm studying electronics engineering and I'm new in vehicle dynamics,
Recently, I make an autonomous vehicle for my final project. In order to control steering angle of vehicle, I have difficulty to measure the steering angle based on curvature road and vehicle velocity.
Anybody...

Hi everyone, i hope this is the right place to post this.
Anyway, I'm creating a game, and I'm trying to calculate and project future car movement path based on steering angle of the wheels. By using equation:
r = wheelbase / sin(steeringAngle)
I'm able to calculate turning radius. But the...
Does anyone know if there's a backup linkage between the ball nut and the steering pinion so that the nut doesn't lock up the rack if the power goes out?
Thanks.
Hello
I tried to calculate the minimum force needed to apply on the knuckle to make a turn.
The important factor is the normal load (due to the weight of the vehicle) when the vehicle is not moving. I know the kingpin angle, scrub radius, knuckle arm, caster. But I am not sure how to proceed...
Hii,
I am designing a rack and pinion steering system .I have strucked in finding 1)rack displacement,2)tie rod length.
The inputs that I have inner and outter wheel lock angles,turning radius,lock to lock turns,steering ratio. If I get rack displacement,I can get steering arm...
Ok so for a project of mine I need to calc. the force required to steer an articulated heavy on road vehicle and to overcome friction (so I need to calc frictional forces too). I understand I need to draw FBDs but it has been a while since i have done that and I have never worked with an...
I'm working on the design project with my partner for mechanical engineering machine design course. We're modeling the rack and pinion used in power steering system.
How do you determine the cost estimate for the rack and pinion? Any specific steps we need to follow?
Design Project

- Analysis of all functional requirement of the product
- Consideration of various preliminary design options (possible solutions)
- Detailed analysis of engineering performance...
I would be grateful for any assistance
I'm attempting to calculate the load on the bushing in the kingpin post on this steering axle. I've uploaded a pdf of the assembly. The load would be perpendicular to the kingpin center line at the top and bottom of the bushing. I'm not certain how...
Hi Guys,
If I were to build a model car, with each wheel having it's own servo, then how can I make it turn in one direction.
Say if I want to turn left, if I cut power to the front left and reduce the speed of the rare wheels will the front left wheel act as a pivot? Or should I cut power of...
Hi,
I am new to control system and coding.my problem is suppose we have a steering value and know we need to turn the vehile. I facing difficulty in understanding some equations.

but I am facing difficulty to understand...
Hi all,
I am trying to select a motor for a project that will have enough torque to operate the steering wheel of a golf cart. I'm trying to avoid over design as I want to be as economical as possible. The problem that I am having lies in determining the torque that is required to move the...
Hi every one,
i am a mechanical engineer working on a project hydraulic steering :smile:. i want to know that in power steering systems it has been used. but the thing is as far i know that the modern power steering system uses a hydraulic cylinder in addition to the rack and...
Simple Question (I hope) being that air flow and water flow are similar...I own a Hobie ProAngler Kayak that I've modified. I built a transom mount and added an electric trolling motor (Motorguide, Varimax T-55). The Kayak's normal propulsion is a pedal drive system that uses wing-like flippers...

Why is it when a tread on one side of a tank stops the other side which is still moving will 'skid' in the direction of that tread? This is used to steer a tank but what is the physics behind this please
Hi,
I have these equations which represent the car steering angles and velocity, but I could not understand how do the operate.They are used for continus turning motion without keeping track of the car angle Beta. I would like some hints if anybody is familiar with them or have any other...
Hypothetically:
-car is aligned properly
-crown has nothing to do with anything
-the steering wheel is on the Left and you weight generously 200lbs.
If you were to draw vectors and include G forces and everything you can think of for this incidence, what would you conclude?
You are...

Hello,
I am currently designing a steering wheel and I'm in need of some advice. I can't seem too find a suitable button for my paddle shifters. I am looking for a button that gives defined user feedback and that takes a bit of force to push it, but it also have to be reasonable size. If...
Does a certain position let you exert more torque on the steering wheel?
I've heard 10 and 2 o'clock. I've also heard 9 and 3 o'clock.

Hi guys,
I'm trying to make a rudimentary projector of sorts using a low power (class 1) laser diode. I'd like to shine the laser onto two mirrors: one would control the horizontal portion of the scan, and the other would control the vertical portion of the scan.
My problem is this: what...
Hi all!
I am making a tractor's front wheel steering arrangment with driving front wheels driven through hydraulic motors. Because of space constraint I was wondering if steering axis (kingpin) can be shifted towards front of wheel axis ie positive mechanical trail but without any castor...
Hello all,
With all-electric car designs becoming more popular, I was wondering if it was really necessary to have all that mechanical linkage in the front of an automobile to steer. Assuming independent electric motors for each wheel, and drive-by-wire technology, a simple alteration in...

turning radius = 4.6 mts
wheel base= 2360mm
track=1495mm
also can you please suggest the relation for steering angle and turning radius and what are the values necessary for calculation of steering...

Hi :smile:!
I am doing the steering of our FSAE(formula racing car). will be using rear steer with a lot of ackermann.
One particular strategy i came across for finalising stering arm angle is, you vary your steering arm angle (angle seen in plan between steering arm and uprights) so that...
