The tractor is used to push the pipe of weight W. To do this it must overcome
Question:
The tractor is used to push the pipe of weight W. To do this it must overcome the frictional forces at the ground, caused by sand. Assuming that the sand exerts a pressure on the bottom of the pipe as shown, and the coefficient of static friction between the pipe and the sand is μs, determine the force required to push the pipe forward. Also, determine the peak pressure p0.
Given:
W = 1500 lb
μs = 0.3
L = 12 ft
r = 15 in

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
