Chapter 5.3, Problem 33PP

To determine

To Sketch: Free body diagram of ant.

Explanation of Solution

Introduction:

Free body diagram: It is an illustration which is used to show the magnitude and direction of all forces acting on the body.

An ant climbing at steady speed up the side of its anthill is shown.

The inclination angle is $30°$ with the vertical

  

Here,

  $F_g$ is weight of ant acting downward.

  $F_{gx}$ is component of weight in $x$ direction.

  $F_{gy}$ is component of weight in $y$ direction.

  $F_N$ is normal force acting perpendicular to the inclined plane.

  $F_f$ is the frictional force.
