Pulley vibrations can transfer to the support bearings and other components of the machine, causing premature or even catastrophic failure. This is why pulleys used in belt drive systems almost always undergo some form of balancing. Centripetal vs centrifugal: There is much debate in science, physics, and engineering circles about which is the ...

A scale of 1 cm to 1.0 kN is the most suitable for this scenario. Step 2: Use grid paper to draw the vectors top to tail and to scale. Step 3: Draw the resultant vector and measure its length. Step 4: Use the scale to convert the length to kN. The resultant force is 8.6 cm, meaning the resultant force is equal to 8.6 kN.

Unbalanced forces change the motion of an object. This happens in two ways. If an object is at rest and an unbalanced force pushes or pulls the object, it will move. Unbalanced forces can also change the speed or direction of an object that is already in motion. A game of tug-of-war is a great way to illustrate an unbalanced force.
