Static Equilibrium of a Particle
F1 = 9 N
F2 = 10 N
α = 57
β = 59
To Maintain Static Equilibrium,
F1 * cos(α) + F3 * cos(γ) = F2 * sin(β)
9 * cos(57) + F3 * cos(γ) = 10 * sin(59)
F3 * cos(γ) = 3.67 -------------1
F1 * sin(α) + F3 * sin(γ) = F2 * cos(β)
9 * sin(57) + F3 * sin(γ) = 10 * cos(59)
F3 * sin(γ) = - 2.397 -------------2
Dividing eq 2/1
tan(γ) = - 2.397/3.67
γ = tan^-1(- 2.397/3.67)
γ = - 33.15o
F3 * cos(-33.15) = 3.67
F3 = 4.4 N
Static Equilibrium of a Particle A particle is subjected to three forces, F_1, F_2 and F_3....
Can anyone help with this question? Forces F_1, F_2, F_3 are defined as follows: F_1 = 10n_1 1b, F_2 = -15n_2 lb, F_3 = 20 n_3 lb, where n_1, n_2, and n_3 are the unit vectors shown in Fig. 1. Determine the magnitude and direction of F, + F2 and compare |F_1 + F_2| with |F_1| + |F_2|. Is the magnitude of the sum of two vectors ever equal to the sum of the magnitudes of the vectors? Draw a...
Three forces, F_1 = 40 N, F_2 = 20 N and F_3 = 10 N, are acting on a block of mass 4 kg as shown. The block is sitting on a horizontal surface with coefficient of kinetic friction mu_k = 0.12. The angle between F_1 and F_2 is 30 degree. What is the magnitude of: a) the friction force k_k? b) the resulting acceleration of the block in x-axis?
The three forces shown in the figure below act on a particle (with F_1 = 47.0 N, theta_1 = 63.0 degree and theta_2 = 27.0 degree). If the particle is in translational equilibria, find F_3 the magnitude of force 3 and the angle theta_3
A particle is acted on by forces given, in newtons, by vector F_1 = 2.77 cap i - 14.2 cap j and vector F_2 = 2.98 cap i + 4.36 cap j. (a) what is the x component and (b) y component of the force vector F_3 that balances the sum of these forces? (c) What angle does vector F_3 have relative to the +x axis?

Three forces acting on an object are given F_1 = (-2.45i - 2.40j)N, F_2 = (5.40i)N, and F_3 = (43.5i + 47.0j)N. The object experiences an acceleration of magnitude 3.50 m/s^2. What is the direction of the acceleration? What is the mass of the object? If the object is initially at rest, what is its speed after 18.0? What are the velocity components of the object after 18.0s? A bag of cement of weight 500 N hangs from three wires...
Can someone help me with college physics question. Three forces act on a 2.00-kg object at angles theta_1 = 40.0 degree, theta_2 = 60.0degree, and = 20.0degree as shown in Figure 4-29. Find the magnitude of F_2 and F_3 if the magnitude of F_1 is 1.00 N and the acceleration of the object is 1.50 m/s^2 toward the +x direction.
In this lab you will be given two different sets of vectors to add together. In Activity 1, you will add position vectors: in Activity 2 you will add forces. Vector addition is an important concept in physics. To be well prepared for the lab you need to solve the following example. Make sure to show all your work in detail. Write the equations first, and then plug in the numerical values. Do not forget to do unit conversions. Use...
