    Analyzing applied torque to one of lug nuts instead of wheel center

    Thanks for your drawing. What about acceleration force that the tire exerts to the ground and causes movement of the car?

    Analyzing applied torque to one of lug nuts instead of wheel center

    I replaced the black picture with a bright one.

    Analyzing applied torque to one of lug nuts instead of wheel center

    Constructing the normal. Could you please edit this picture to show the force and the lines?

    Analyzing applied torque to one of lug nuts instead of wheel center

    Lug nut torque is not my question because I already know the torque which I'm applying to the nut (35 nm). When I apply this amount of torque to the nut, the wheel starts rotating very slowly and the car begins moving forward. So, there is a force that moves it forward and I want to know the...

    Analyzing applied torque to one of lug nuts instead of wheel center

    We all know that torque consists of force and distance. If we apply torque to the center of a car wheel, the force that the tire exerts to the ground can be calculated by dividing the torque by tire radius but what about applying torque to one of lug nuts which is off center? In the above...

    The effect of slightly slanted distance (arm) on torque output

    Thanks a million! This is exactly what I wanted to know! So, that angle doesn't make a huge difference in the final torque output. I think the other and simpler alternative would be to just measuring the length from extension square drive to wrench drive (center to center) instead of measuring...

    The effect of slightly slanted distance (arm) on torque output

    Thanks for your answer. Yes, I'm completely aware of the increased torque due to increased length and this has also been mentioned in the wrench manual with the following formula: In fact, I made the extension to both increase the range of my wrench and to operate it with less force. For...

    The effect of slightly slanted distance (arm) on torque output

    Hi everyone. In most cases when torque and lever arm are being discussed, it is the angle between the force and the arm that matters (like in the following picture). However, non of the articles that I have read so far have mentioned anything about the distance between force and fastener being...

    Calculating the force of an average car

    You are right but the peak torque is reached in 4250 RPM and at this RPM the engine is turning so fast that the difference in time between the explosion of each cylinder becomes so negligible (less than hundredth of milliseconds) that we can almost think of it as a linear-force motor like an...

    Calculating the force of an average car

    Power is the rate at which a certain amount of work is done. It is not a force. In this topic, I'm only interested to know about sheer force an internal combustion engine can produce and I have come into big problems! According to my research, an average IC engine produces about 1 ton of force...

    Calculating the force of an average car

    What is confusing for me is that if we ignore the multiplication effect of the transmission, the engine itself seems to be as weak as or even weaker than a human being ! :oldconfused: The engine produces 155 nm and with a tire radius of 0.289 meters it can produce 536 Newtons of force which is...

    Calculating the force of an average car

    Can the same car apply almost 770 kg of force to a wall if it moves horizontally? (Assuming tire friction is zero) Or we can put it this way: If a human being is between the car and the wall, he will experience a crushing force of around 770 kg.

    Calculating the force of an average car

    Because I wanted to add the multiplication effect of transmission gears. Force = Torque / Distance Yes, I used an elevator as an example. I just want to know the amount of kilogram force the car wheels can produce.

    Calculating the force of an average car

    Hi everyone, I'm interested to know how much kilograms force an average car can produce. I made the following calculations to answer my question but I'm not sure if I'm right or wrong! Imagine we have a 1.8L engine that can produce a max torque of 155 nm @ 4250 RPM. 1st gear ratio = 3.455...

    I calculating maximum gradient climbing ability of my car

    I said it is negligible only at very slow speeds but not so at highers speeds such as 100 km/h or more. I found this formula: My car's frontal area = 1.99 square meters Drag coefficient = 0.31 cd
