So, the wind force needed to push the beam and tires would just have to be greater than the friction force.

After I find the normal force and friction force, would I just add both of them up? Would that be what I'm looking for to find the force required by the wind to push the beam the distance? Thanks a lot for the help.

Here is a view from above.

Yes, the ashphalt is horizontal. The beam is attached to the top of each tire, and the back tire is a fixed point. I'm trying to figure out how much wind it took to blow the front tire 90 degrees. I drew up a couple of diagrams, and will attach both. The first one is a side view and I will...

Ok, I've taken the moment to find the weight of the beam at each tire location. So, I should have all the numbers to find the normal forces at both points. Whats the next step?

The normal force would equal m x g + weight of beam??

The normal force would just be mass x gravity, I think. Correct?

That's not all the numbers. I know the applied force on top of each tire and the coefficient of friction between rubber and asphalt, and the center of gravity of the beam. It's been a couple of years since I've taken Dynamics, so I'm having a tough time coming up with which equation to use. I...

Homework Statement There are two tires separated by a few feet, with a weighted beam attached on top of them. The beam's weight isn't distributed evenly. One of the tires is a fixed point. The other tire slides (doesn't roll) 90 degrees. How do you determine the force required to slide the...

Wind speed vs. an airplane problem Homework Statement An airplane weighs 6,000 lbs. It is parked on the ground and one of it's back wheels acts as a pivot and can't move (the other back wheel and front wheel can move). Assuming that the wind is blowing directly into side the plane and not...

Sorry, it weighs 6,000 lbs. The wind is blowing directly into the side of the plane with no angle. Also, no time duration was given. If the problem needs a time, use, say, 5 minutes.

Homework Statement Ok, an airplane weighs 6,000 (think of the airplane as a triangle) and one of the back two wheels is stationary and acts as a pivot. The airplane is on the ground. How fast does the wind need to be blowing to push the front wheel 90 degrees from the original location...
