Hello, Due to my meager mechanical physics knowledge and my meager math talent, I am stuck on this matter: How are the angle of a vehicle turning related to its wheel's displacement. Let me elaborate: I have a 3 wheel vehicle. It relies on the 2 motors in the back to motivate it. Each...

I know that because of the rolling constraint, V(cm)=R*w [w=omega]. Also, if I want to find the velocity of particle i, i can sum V(cm) and V(i, relative to the center of mass). But how do I determine V(i, rel)? For example, if I am given the speed and radius of a wheel, how fast is a point...

A Ferris wheel consits of a giant wheel that rotates slowly in a vertical plane. people sit upright in chairs ont he ferris wheel. The type of force that provies the centripetal acceleration for the people at the top of the wheel as it rotates is called: A.) gravity or B.) normal i'm...

Hi, What is the simple principle that governs cars with 3 wheels going forward? What are the specifications for the front wheel and the back 2 wheels? Do they have to have a specific ratio? Or something else? Please advice.

A wheel on a game show is given an initial angular speed of 1.22 rad/s. It comes to rest after rotating through 3/4 of a turn. Find the average torque exerted on the wheel given that it is a disk of radius 0.71m and a mass 6.4kg. I'm lost. I don't really know where to begin. I know the...

Hey all, I'm having a little trouble finding infomation on skateboard physics. More specifically, i need to find out the different physics concepts (ie. forces) that act on skateboards and their wheels. How does friction effect the performance of skateboards and how are skateboards designed...

Hello All, I was wondering what the equation is to get the torque on a wheel from a point (x,y) on the wheel, with an applied force vector on the point. I know I will need to use some combination of Sin or cosine, but I'm not sure how to set up the math for it. Any help would be appreciated...

Is there a formula which relates the angle of a steering wheel from normal position (theta) and the radius of curvature (r) of the arc that an average vehicle moves through? (assuming power steering, since that's the most common) Such a formula would be useful in calculating centripetal...

Why did nature never invent the wheel?

Background: For those of you who don't know, a fifth wheel RV is a recreational vehicle (trailer) that is hitched into the bed of a pickup truck, in front of the rear axel of the pickup. The rest of the trailer trails behind the pickup truck on two or three axels of it's own. Pickup's that...

A wagon wheel 1.00m in diameter consists of a thin rim having a mass of 7.25kg and six spokes each having a mass of 1.30kg. Determine the moment of inertia of the wagon wheel for rotation about its axis. I thought that I could simply sum the masses (7 of them) and the multiply them by them...

Hi folks, Would appreciate any help with this problem A chemistry student with a mass of 74 kg is riding a steadily moving Ferris wheel. When she is at the top of the Ferris wheel, the normal force from the seat on to her body has a magnitude of 556 N. a)What is the magnitude of the...

This is a hard problem! :cry: Anyone know what my mistakes are?? ----- A passenger on the ferris wheel normally weighs 367 N. The ferris wheel has a 14 m radius and is equipped with a powerful motor. The operator revs it up so that the customers at the top of the wheel feel zero g's (they...

The axle of a wheel is mounted on supports that rest on a rotating turntable as shown in Fig. 10-50. The wheel has angular velocity w1 = 50.0 rad/s about its axle, and the turntable has angular velocity of w=35.0 rad/s about a vertical axis. (Note arrows showing these motions in the figure.)...

Can anyone help me in solving this question? At t=0, a wheel is rotating about a fixed axis at a constant angular acceleration has an angular velocity of 2 rad/s. Two seconds later it has turned 5 complete revolutions what is the angular acceleration of this wheel??

I would really like someone to answer this simple question. I have searched the net and i cannot find the answer, i know i have only just read it but i can't remember where. Basically all i want to know is the name of the movement of a while when it is moving a vehicle (i don't mean around...

A fairground wheel is rotating in a vertical plane and carriages travel round a circle of diameter 40m at a constant speed. The carriages complete one revolution in 3.5min I need to calculate the speed of the carriage from the top of the wheel to the bottom: Circumference = 2 pi r...

A clump of mud is attached to the outside of a bicycle wheel, radius 700mm. how many revolutions per second does this wheel have to spin to fling off the mud if the coefficient of static friction attaching it to the wheel is 0.64. The real trouble I am having with this is find the normal...

The question is : The speed of a car traveling on a straight horizontal road is V. What is the speed of the point P on the tyre of the car ? (A) 0.5V (B) V (C) 2V (D) 3V i got try to solve it myself, and i get the...

Hi All! This is my first real post here. I have a pretty basic question regarding rotating objects and the manner in which the rotation becomes a translation. If I drop a bicycle wheel against the ground, it bounces back toward my hand. But if the wheel is spinning as it falls, it will...

Hi, I have a few questions, thanks for any help you can give! 1. If a wheel is rotating at a rate of 3.1 revolutions every 3.6 seconds. Through what angle, in radians, does the wheel rotate in 1 second?? 2. A car can negotiate an unbanked curve safely at a certain maximum speed when the...

Just need to know if I'm on the right track (again): A wheel of mass M has radius R. It is standing vertically on the floor, and we want to exert a horizontal force F at its axle so that it will climb a step against which it rests. The step has height h, where h < R. What minimum force F is...

Ferris Wheel ...Trick Question? This is one of those that might be a typo or I am really missing something. A 250lb student is riding on a steadily rotating Ferris Wheel. If the student has an apparent weight of 250lb at the top what will be the students apparent weight at the bottom? What...

The problems reads, A carnival Ferris wheel has a 14.2m radius and completes one revolution about its horizontal axis in 10.1s. Consider the time interval from the instant when a passenger is at the lowest point of the uniform circular motion to a clock reading 5.05 seconds later. What was the...

How many revolutions per minute would a 15m diameter Ferris wheel need to make for the passengers to feel weightless at the topmost point?

Wheel size and speed help! Okay, my father and I have been an argument for days on this. We were arguing about wheel sizes and their effected distance traveled. A larger wheel has a greater circumference; therefore one revolution will travel a farther distance. Here's the argument. If you have...
