## Example (1): Two forces F₁ = 50N, F₂ = 60N are applied to a box on horizontal level as in Figure. F₁ is applied with an angle of 45° on an object and F₂ is applied with zero angle. What is the total resultant force on the object and at what angle it is applied? - First, we need to calculate th...

## Example (1): Two forces F₁ = 50N, F₂ = 60N are applied to a box on horizontal level as in Figure. F₁ is applied with an angle of 45° on an object and F₂ is applied with zero angle. What is the total resultant force on the object and at what angle it is applied? - First, we need to calculate the resultant force (R) ### Free-Body Diagram: * F1x = F1 cos 45° * F1y = F1 sin 45° * F2x = F2 * F2y = 0 ### Total Force: * **x-axis:** F1x + F2x = Rx = F1 cos 45° + F2 = (50N)(cos 45°) + (60N) = 95N * **y-axis:** F1y + F2y = Ry = F1 sin 45° + 0 = (50N)(sin 45°) = 35N
