Im curently trying to work out the upwards force of the wheel of a car as it passes over a hump in the road. I have drawn a very simple diagram to illustrate this. If anyone could help me calculate this force that would be most helpful. I understand as the wheel is traveling along the road...

The equation that is required in my assignment to calculate the energy of the internal air flow of a manifold is: Fluid Energy= P + 1/2 ρv^2 Therfore i understand the bernoulis conservation energy equation, but i canot find a definition/explanation to this equation which is very similar to...

thanks for the reply. Sorry for the poor effort of writing out the equation, I am use to writing equations out in microsoft word in the set format. However the equation that tiny tim wrote is what i was trying to get at. Thanks for all your descriptions that has more than answered my...

I have been using the following equation in my assignments to calculate the air flow energy: (0.5*D*V^2)+P where: D= density V=veolcity P= Pressure I understand bernoulis conservation of energy equation is similar to the above however bernoulis equation does not apply to a compresable fluid...

updated diagram the downward force at the top is the wieght transferred by the car

once again ranger mike that is very helpful.However assuming that The co-efficent of friction is 0.5 between the wheel and road The wheel radius is 190.5 MM The efective radius is 105 MM The force of the vehicle acting directly downwards on the wheel is 6867N (700*9.81) The required...

The vehicle parameters are: V1=100 M/s V2=50 M/s T=10 s M=100 Kgs Therfore the vehicle is traveling at 100 m/s and slows down to 50 m/s in 10 seconds. As a results this means that the Total Required braking force is 5000N. From taking moments about vehicle FBD i found that the Normal...

Thanks for your reply jack that has made it much clearer. Yes it is for a car, i have worked out that their is a weight distribution of 70 percent on the front wheels. As you have sugested i will use the torque found with the normal friction force at the tire contact patch, for the shear...

Brake Disc Design- Torque Acting On Wheel Stud Bolts I have currently been working on designing a brake disc assembly. The current problem i am having is trying to workout the force acting on each wheel stud. The frictional force of the brake pad is 3.2 KN with an efective radius of...

Homework Statement I have currently been working on a group project designing a brake disc assembly. The current problem i am having is trying to workout the force acting on each wheel stud. The frictional force of the brake pad is 3.2 KN with an efective radius of 105MM from the center...
