Question:
A machine of mass M is to be moved over a level surface using a series of rollers for which the coefficient of rolling resistance is ag at the ground and am at the bottom surface of the machine. Determine the appropriate diameter of the rollers so that the machine can be pushed forward with a horizontal force P. Hint: Use the result of Prob. 8-131.
Units Used:
Mg = 1000 kg
Given:
M = 1.4 Mg
ag = 0.5 mm
am = 0.2 mm
P = 250 N

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.
