Question
What would be the resultant of three forces, such as those in Fig. 21, if $F_1=4 \mathrm{lb}, F_2=2 \mathrm{lb}, F_2=3 \mathrm{lb}$, and $\theta_1=25^{\circ}, \theta_2=65^{\circ}, \theta_3=140^{\circ}$ ?
Step 1
We have three forces: - $F_1 = 4$ lb at angle $\theta_1 = 25°$ - $F_2 = 2$ lb at angle $\theta_2 = 65°$ - $F_3 = 3$ lb at angle $\theta_3 = 140°$ Show more…

Four forces, $\overrightarrow{f_{1}}, \overrightarrow{f_{2}}, \overrightarrow{f_{3}},$ and $\overrightarrow{f_{4}},$ are acting on an object and lie in the same plane, as shown. The forces $\overrightarrow{f_{1}}$ and $\overrightarrow{f_{2}}$ act in an opposite direction to each other, with $|\overrightarrow{f_{1}}|=30 \mathrm{N}$ and $|\overrightarrow{f_{2}}|=40 \mathrm{N} .$ The forces $\overrightarrow{f_{3}}$ and $\overrightarrow{f_{4}}$ also act in opposite directions, with $\left|\vec{f}_{3}\right|=35 \mathrm{N}$ and $|\overrightarrow{f_{4}}|=25 \mathrm{N} .$ If the angle between $\overrightarrow{f_{1}}$ and $\overrightarrow{f_{3}}$ is $45^{\circ},$ determine the resultant of these four forces.
Three forces: F1 (20N, 30 degree); F2 (30N, 60 degree); F3 (10N, 120 degree).What is the magnitude of the resultant force? What is the direction of the resultant force?
Three forces are applied to an object, as indicated in the drawing. Force $\overrightarrow{\mathbf{F}}_{1}$ has a magnitude of 21.0 newtons $(21.0 \mathrm{~N})$ and is directed $30.0^{\circ}$ to the left of the $+y$ axis. Force $\overrightarrow{\mathbf{F}}_{2}$ has a magnitude of $15.0 \mathrm{~N}$ and points along the $+x$ axis. What must be the magnitude and direction (specified by the angle $\theta$ in the drawing) of the third force $\overrightarrow{\mathrm{F}} 3$ such that the vector sum of the three forces is $0 \mathrm{~N}$ ?
