Basic components of force diagram
! Force (letter) !! Nature of force !! Condition for existence !! Magnitude !! Direction
|-
| $m_1g$ || [[gravitational force]] || unconditional|| $m_1g$ where $m_1$ is the [[mass]] and $g$ is the [[acceleration due to gravity]] || vertically downward, hence an angle $\thetaalpha_1$ with the normal to the incline and an angle $(\pi/2) - \alpha_1$ with the incline
|-
| $T$ || [[tension]] || unconditional || needs to be computed based on solving equations. || pulls the mass up the inclined plane.
