Force and Motion in Two Dimensions - juan-roldan
... You will need to apply Newton’s laws once in the xdirection and once in the y-direction. Because the weight does not point in either of these directions, you will need to break this vector into its xand y-components before you can sum your forces in these two directions. ...

... What is the relationship that exists between the diameter and number of teeth of a gear and the speed and torque of the gear? A gear is a toothed wheel used to transmit power. Gears are used for four main reasons: 1) reverse the direction of rotation, 2) increase or decrease the speed of rotation ...

... The force exerted by the string, at either end: • direction is parallel to the string • magnitude (same at both ends) is called the tension Example. Suppose a string can withstand string tension 500 N without breaking. What is the maximum mass M that it can hold suspended in Earth’s gravity? ...
