hello friends i am seek advice on a engineer question (sorry if grammar bad english isn't my first language but i learn) i require to find the moments on a pedal. the pedal is horizonta. as the picture provided the hinge point is at a and there is a support at b. at e a man stands and is 750...

the device that I have is the same as the mirror of this truck.

Let $$Y(t)=tanh(ln(1+Z(t)^2))$$ where Z is the Hardy Z function; I'm trying to calculate the pedal coordinates of the curve defined by $$L = \{ (t (u), s (u)) : {Re} (Y (t (u) + i s (u)))_{} = 0 \}$$ and $$H = \{ (t (u), s (u)) : {Im} (Y (t (u) + i s (u)))_{} = 0 \}$$ , and for that I need to...

After the foot is released from the gas pedal, the car will naturally start decelerating. From my understanding two things are causing this: air resistance and kinetic friction. From my understanding also, in a vacuum and in a place where gravity is relatively small, the car would not...

I have seen motorcycles and bicycles with only one front fork and I was wondering if the mechanics would be similar enough to make it possible to manufacture a bicycle pedal that has only one bearing where the pedal screws into the crank and no shaft passing through the body of the pedal...

Homework Statement To calculate the resultant pedal force from the variables given: Crank (degrees) measured clockwise from vertical, spindle (degrees) measured anti-clockwise from horizontal, tangent force (N) applied to the pedal surface, normal force (N) applied to the pedal surface and...

You have 2 bikes. They only differ in 1 way. The length of the crank arm (where pedal attaches) https://en.wikipedia.org/wiki/Crankset How will these bikes differ when riding? Is one harder to pedal than the other? Why?

Hi All, I am working on a project that mounts an accelerometer to the bike pedal, and requires me to calculate the power that the sensor experiences as the bike is being ridden. However, I am having some trouble understanding the forces that the pedal/sensor experiences. Essentially, I need...

Hi, I'm trying to design a contraption for a project that will move an item/box up and to the side. I have a picture of what it should look like and how it should look like but I need help with the mechanics of it. The box's starting position is In the ground and under a slap of metal or wood...

Homework Statement I think that the equation for the force someone exerts on their bike pedals or the force forward is stated below. can anyone confirm this is true? Homework Equations Fapplied by rider = (weight of rider) (Radius Crank /Radius Tire) (Gear Ratio) The Attempt at a Solution

As per control theory, if a bounded input produces a bounded output then a system can be said to be stable. So assuming that I press my cars gas pedal such that it reaches a fixed position, then the reaction of my car would be to reach a corresponding velocity, and assuming the road to be even...

Ok, New to the forum! I'm rusty in Physics but I'm trying to find this answer...part of a personal project. I'm trying to find the forces involved during cycling, specifically related to the Chainring (Crank), What numbers do I need to know to find this force? Let's say I have: -Maximum...

- You are driving car with 100 mile/hour - You are pressing brake pedal. - The speed of car is suddenly gone down. Decelerated. - However, Wheel is rolling on road without sliding and car stopped smoothly finally.In this case, - the tangent force acting on road surface is related with...

Hi, I'm a triathlete and a hobby constructor. I would like to build a power meter for my bike because the ones on the market are quiet expensive. The idea is to measure the power the rider puts into pedaling by measuring the tension between the pedal and the crank. They are connected with just...

Hello everyone, this is my first contribution in this forum, I'm aware that this question had been asked many times either in this forum or elsewhere and I have indeed read at least one thread with a similar topic, however, unfortunately, I have yet to find specific answers that nail the core...

I was thinking about adding a pedal powered propeller to a kayak and I had an idea:Use a hydraulic pump/motor combo to simplify the design. That way I could have the pedals in front of me and easily route some hydraulic lines to a propeller in the back. I came across this gear driven...

This is in relation to the modelling of pedal input(\theta) to vehicle velocity 'v' by using controllers. In this video() the teacher says that humans accelerate the car NOT by sensing the pedal angle(\theta),but rather by sensing the change in the pedal angle over time(\frac{d \theta}{dt}). I...

As titled: When moving at a constant velocity, say drag force is the only resistive force, don't we want to amplify the force output? why would we want to use a larger gear for the paddle than the rear wheel's? I understand that we will need to paddle faster with a larger gear output...

what is the approx brake pedal force that a person applies while braking on the brake pedal?

Could someone solve this question please? The pedal of a bicycle is 18 cm long. When it is pushed downwards by a cyclist it experiences a force of 350 N. Calculate the moment when the pedal is horizontal and then when it is 65º below the horizontal. Thanks.

I'm attempting to solve a mastering physics problem, but I've seem to run into a dead-end on this problem. I've worked out my solution and I'm certain I've rounded my sig figs correctly, but mp doesn't accept the answer. Homework Statement An 17-cm long bicycle crank arm, with a pedal at one...

I'm trying to replicate the voltages coming from an accelerator pedal, to the ECM, on 6.0 L Diesel engine. I acquired the three separate voltages using an oscilloscope. I have access to two analog output channels on the dyno. Out of the three voltages two them follow each other by a...

Hi. me and my friend have a problem that we can't really agree upon. we are doing an analysis study on a bike's crank and pedal. the first picture shows how we put the force of 210 N. picture 2 shows how we used "fixed geometry" to lock the part in place. now, this is the static...

It is referring to motion ¨terms¨ like friction and rings like that.

Hi, I have a practice question. I have managed to calculate part of it and one last bit I haven't been able to. Hoping you can give me some ideas. I am given a bicycle pedal that is a some distance long and has been pushed downwards by a given force. Here I have been able to calculate the...

So I've got a pedal which sweeps through pi/2 in 1 complete cycle (frequency is known). Is its angular velocity (pi/2)*f or 2pi*f just the same? (considering that it doesn't sweep through 2pi but pi/2)

Hi Well I'm back again with as usual more questions that answers! Ok I would like to build to following as an educational tool: The generator is MY1016 DC PM motor that can produce upto 200watts connected to a child's bicycle. Kids around 10 or 11 should be able to do a 40watts burst...

Hi, this is my first post so sorry it is not a contribution! Anyway, I have a pedal powered business that is doing very well. We use 24v DC Motors as seen here http://buggies.builtforfun.co.uk/FactFiles/motors.html" . Each motor is connected to the back wheel of the bike (we use a diode next...

I am trying to determine the forces exerted on a bicycle pedal crank by the rider so I can analyze the fatigue. I believe that I understand how to conduct the fatigue analysis but I think that the forces on the bike crank are more complicated then I have assumed them to be so far. I know...

Hello all! I am building an effects pedal for my guitar (dont have a choice, I spent all the money I was saving on the guitar). Since electronic components are cheap, for once, I am glad I am studying EE. At first I thought I'd design the circuits myself, but after doing a bit of research, I...

I have a simply question: how much force must be applied to an average car brake in order to fully depress the pedal? Also, if you know the answer, do you know where I could substantiate it? Thanks for any help you can offer.

If you want some background information on the project I'm working on, continue reading. If you just want to help then you can just skip to the bolded part. I'm supposed to build a pedal powered generator for an engineering class with a group. We are using a treadmill motor and pressing the...

Why the more you push the gas pedal , the stronger the car is (say, when pulling something)?

very simple question: Calculate the torque on the pedal shown if a force of 150N was applied in the direction shown. http://img110.imageshack.us/img110/5994/torque6hg.jpg however, i think I am missing the length of the shaft? since the formula is |T| = |r||F|sin (theta), where's my r...

Many traffic warnings issues tell it's much better to brake without pressing the clutch pedal. For instance, we drive a car at 120 km/h and suddenly we have to brake in the shortest distance as possible due to some obstacle on the road. What is better? 1) Should we press the clutch pedal at the...

I am doing a project in Design & Technology and intend to design a product that is to be used by Playstation 2 (or other consols) users. I have a few questions, which I would be very grateful for if I get a few replies: Do you have a Steering wheel and pedal that you use to play car games with...
