The maximum amount of pulling force a truck can apply when driving on

concrete is 10,560 N. If the coefficient of static friction between a trailer and

concrete is 0.8, what is the heaviest that the trailer can be and still be pulled

by the truck?

Respuesta :

Answer:

Explanation:

Let the weight of the truck be W . reaction force R = W

Maximum frictional force = μ R

= .8 x W

So for movement of truck

Pulling force = frictional force

10560 = .8W

W = 13200 N

weight of heaviest truck required = 13200 N .
