So what you should have thought about or deduced is that N2 here

is a positive value if the front tires are pushing down on the ground.

However if N2 ends up equalling 0 or a negative

number, that means the front tires have lifted off the ground.

And the truck has tipped and so lets double check to make sure it won't

tip, by summing moments about point 8 and,

and, and, and finding well actually we don't

even need to sum moments about point 8. What we can do is we can say okay

what, what, what was N1 and then we will just sum forces in the y direction.

So N1 was given here we said that the intention that we, we

could develop was 1370 pounds so that means that N1 ends up being

13, 380 300, 3870 pounds. if I sum

forces in the y direction now I find out that N2 will need

to be 2,100 pounds. And so since N2 in this situation ends up

being greater than 0, you find out that yes, indeed the truck doesn't tip.

And as I mentioned earlier, if you didn't want to go through this type

of analysis, you could have also gone

through an analysis where you sum moments about

a as the other equation of equilibrium.

you'd have your tension force in the cable, you'd have your weight,

you could solve for N2 again it would amount to be 2,100 pounds.

And since it's positive you know that the front wheel

is staying on the ground and the truck doesn't tip.

And so the amount of tension that you can develop in the cable, the

max tension that you can able to develop in the cable is 1370 pounds.

maybe as an exercise on your own, think about your

vehicle if you have one or somebody's vehicle and find

out if that's enough to, do you think that would

be enough to pull that, that car out of this situation.
