Calculate Force Required to Lower Load







Formula

The formula to calculate the Force Required is:

\[ F = W_{\text{load}} \cdot \tan(\Phi - \psi) \]

Definition

Force Required is any interaction that, when unopposed, will change the motion of an object. In other words, a force can cause an object with mass to change its velocity.

Example Calculation

Let's assume the following values:

Using the formula:

\[ F = 53 \cdot \tan(0.21816615649925 - 0.4363323129985) = -11.7498171200735 \text{ N} \]
