Title: What formula is to calculate resultant forces? Post by: oemBiology on May 15, 2019 I would like to know on what formula is to calculate resultant forces from 3 objects in 2-D.
Object 1 : Force = 1 and Angle = 0 Object 2 : Force = 1 and Angle = 136 Object 3 : Force = 1 and Angle = 236 Does anyone have any suggestions? Thanks in advance for any suggestions Title: Re: What formula is to calculate resultant forces? Post by: duddy on May 15, 2019 Sounds like you're adding vectors. You'd have to break down each force into its x-y components using trigonometric ratios.

Title: Re: What formula is to calculate resultant forces? Post by: bio_man on May 15, 2019 Good work.
I have the solution for you. Step 1. Plot the point on the polar plane or x-y plane. Step 2. Draw the vector from the origin to the point. Step 3. Use the tangent function to relate the x and y coordinates. Tangent relates opposite over adjacent within a right triangle. Step 4. Use inverse tangent to find the angle. Step 5. If the vector lies in the third quadrant (as shown), add 180 degrees to the angle you found in Step 4.
