Answer to Question #164841 in Physics for Viloshnee Jairaj

Question

A crate of 200N is pulled. A force of 100N at an angle of 30° to the horizontal is exerted on it. There is a frictional force of 20N between the crate and surface. Draw a force diagram

Answer 1

Let's draw the diagram:

As we can see from the diagram, there are four forces that act on the crate: the horizontal pulling force $F_{pull}$ of 100 N directed at an angle of 30° to the horizontal, the frictional force $F_{Fr}$ of 20 N directed in the opposite direction to the motion of the crate, the force of gravity (or the weight of the crate) $W$of 200 N directed downward and the force of reaction $N$ that is equal in magnitude to the weight of the crate and directed upward.
